"Additive Manufacturing of Thermosetting Polymers and Composites with Tunable Functional Properties via Frontal Polymerization"

Thermoset polymers and their composites have been traditionally used in many applications
due to their good combination of mechanical properties, thermal stability, and chemical resistance.
Adoption of thermosetting materials in additive manufacturing (AM) for rapid creation of
prototypes or development of parts with complex geometries, however, has been limited by the
long and energy-intensive curing processes often required for curing the monomer. Here, we
present a novel AM technique to address the existing limitations with thermoset printing and
manufacture thermoset parts with various functional properties. In our approach, we use direct ink
writing (DIW) technique to controllably deposit a thermosensitive ink based on dicyclopentadiene
and simultaneously cure and solidify the ink after it exits the printing nozzle via frontal
polymerization. As a result, we can create freeform structures with no post-cure step, which is
difficult or impossible to achieve using other printing techniques. We also tailor the functional
properties of the printed parts by controlling the composition, reactivity, and rheological properties
of the inks. As a result, we can print thermoset parts with tunable mechanical properties from
stretchable, elastomeric parts to stiff polymers to fiber-reinforced polymer composites and also 3D
print foams with various densities and mechanical properties.

The grand prize award includes:
  • $1,500 cash award and an award plaque.
  • An invitation to present the winning paper at the TRFA  Annual Meeting on May 2-5, 2022, in Dallas, Texas with complimentary registration for one person.

"Layered Epoxide-Amine/Boron Nitride/Graphene Nanocomposites for Enhanced Multifunctional Shielding"

The rapid development of high-power electromagnetic wave sources in the modern
era has the ability to interfere with aircraft electronics. Multifunctional nanoparticles have
been used in aerospace grade matrices to combat this issue; however, little research has
been conducted in multilayer orientations combining thermally and electrically conductive
species. Epoxide-amine matrices with electrically/thermally conductive nanoplatelets
were prepared using tetragylcidal 4,4’-diamindodiphenylmethane (TGDDM),
4,4’- diaminodiphenylsulphone (DDS), and SU-8, an octa-functional cross-linking agent.
Hexagonal boron nitride and graphene nanoplatelets were used as functional particles.
Multilayer thin film laminates were prepared. The dispersion, layer orientation, rheological
properties, and electrical/thermal conductivity of the multifunctional systems were
measured using parallel plate rheometry, SEM, optical microscopy, TGA, and 4-point
probe electrical conductivity test analyses. FT-IR analysis was also conducted to quantify
the matrix advancement throughout the cure profile. The data collected indicated that
incorporation of the functional platelets increases the viscosity of the system while
improving the electrical conductivity and inherent shielding abilities of the polymer matrix

The honorable mention includes:
  • A $500 cash award, and an award certificate will be presented at the meeting
  • Complimentary registration for the TRFA Annual Meeting in Dallas, TX.
  • Travel Allowance for one person up to $500
  • Presentation of their paper during the technical sessions of the TRFA Annual Meeting

“Recycling Cross-Linked Polyurethane Foam using Twin Screw Extrusion”Cross-linked polyurethane (PU) is extensively used as thermosetting foam, however, methods to directly reprocess PU foam waste derived from commercial sources into similar value materials have not been developed. We demonstrate that introducing dibutyltin dilaurate (DBTDL) to cross-linked PU foams and films enables their reprocessing at elevated temperatures via carbamate exchange. Both synthesized and commercial PU foams were continuously reprocessed using twin-screw extrusion to remove gaseous filler to produce PU filaments or films with elastomeric or rigid thermosetting mechanical properties. Throughout this process, cross-link density and tensile strengths are maintained quantitatively in synthesized PU foam recluding undesirable side reactions as well as changing material morphology. These findings will enable the bulk reprocessing of commercial thermosetting PU waste and inspire the further development of reprocessing methods for other thermosets and the compatibilization of chemically distinct cross-linked materials.
The grand prize award includes:
  • $1,500 cash award and an award plaque.
  • An invitation to present the winning paper at the TRFA  Annual Meeting on April 28, 2020, in Denver, Colorado with complimentary registration for one person (canceled due to the COVID-19 pandemic).

  • Additional travel allowance for one person up to $500.

“Synthesis of High-Performance UV-Curable Crosslinked Coating Films via Grafting of HEMA Functionalized Methylene Malonate”Novel methylene malonate (MM) monomers can be synthesized economically from petro-based or renewable feedstocks. Interestingly, they undergo reactive anionic polymerization in an aqueous ambient environment. This attribute provides a powerful and simple new approach to enhance the properties of emulsion polymers, waterborne coatings and related applications that would benefit from greener chemistries. In this work, we have demonstrated the direct emulsion polymerization of MM in aqueous solutions at various pH values and functional groups. Polymerization was also readily initiated from latex particle surfaces. This strategy was employed to introduce high functional group densities to the latex particles, providing attributes, such as ultraviolet (UV) crosslinking, free radical crosslinking, and mechanical properties to the latexes and coatings derived therefrom. Systematic studies were conducted on the UV curing of methacrylate functionalized latex films to determine their thermal properties, mechanical strength, crosslinking density, and chemical composition. Rapid UV curing and high crosslinking densities enabled the synthesis of high-performance coatings based on a very simple in-situ latex modification. This study provides a simple, new, in-situ and readily scalable chemistry and methodology to significantly enhance the performance of emulsion polymers, latex systems, and coatings.

“Renewable thermoset polyurethanes dispersions from bio-based isocyanate”A series of high bio-based carbon content polyurethane dispersions (PUD) was successfully synthesized from dimer fatty acid diisocyanate (DDI), castor oil (CO), alkoxysilane modified castor oil (MCO), and dimethylolpropionic acid (DMPA). This work focused on the improvement for the final performance of the renewable DDI-based PUD as well as the discussion of structure/property relationships. The chemical structure of MCO and Si-O-Si crosslink network structure on the dry-film of PUD were characterized by Fourier-transform infrared spectroscopy (FTIR) and solid-state 29Si NMR. The effect of alkoxysilane and NCO/OH ratio on DDI-based PUD were investigated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), tensile tests, and electrochemical impedance spectroscopy (EIS). The glass transition temperature, Young’s modulus, and tensile strength increased with the incorporation of alkoxysilane and increasing NCO/OH ratio. In the meanwhile, the initial degradation temperature and elongation-at-break were reduced with increasing content of alkoxysilane. Finally, the alkoxysilane modified DDI-based PUD exhibited excellent corrosion resistance after the immersion in NaCl solution for 28 days. In general, the present research suggested that through appropriate modification, the DDI-based PUD with high bio-based carbon content could exhibit great mechanical properties and excellent anticorrosion properties.
