2023 Excellence in Thermoset Polymer Research Award Winners

"Recyclable, self-strengthening starch-based epoxy vitrimer facilitated by exchangeable disulfide bonds"

Epoxy vitrimers have emerged as a new class of self-healing, recyclable, and reprocessable materials, offering new opportunities to traditional epoxy thermosets by improving life-span, while providing additional functionalities. Nevertheless, retaining 100% of the original mechanical performances remains difficult for vitrimers after several reprocessing cycles due to progressive changes in the vitrimer networks during rearrangements. In this study, we designed a novel epoxy vitrimer with a higher renewable content compared to conventional epoxies by using renewable materials. The bio-based epoxy vitrimer was synthesized from epoxidized starch amylopectin together with diallyl disulfide, that is naturally found in garlic, and a thiol (pentaerythritol tetrakis(3-mercaptopropionate) (PETMP)). Diallyl disulfide and PETMP enabled the formation of a recyclable, and reprocesseable, vitrimer network. The epoxy vitrimer displayed unprecedented self-strengthening after 5 recycling cycles (tensile strength increased over 900%) caused by the mechanically-induced homogenization of the diallyl disulfide/thiol and the starch epoxy phases during the recycling process, thereby increasing the vitrimer cross-linking density during reformation. Reprocessing the vitrimer 5-times improved the mechanical and thermal properties, raising glass transition temperature, Young’s modulus, and tensile strength from 7°C to 25°C, 2.98MPa to 268MPa, and 1.87MPa to 18.47MPa, respectively. Hence, capitalizing on mechanically-induced phase homogenization during the vitrimer reprocessing, this work introduces a strategy for the design of self-strengthening bio-based and recyclable thermosets.

"Neighboring Group Participation in Ionic Covalent Adaptable Networks"

Covalent adaptable networks (CANs) typically require external catalysts for efficient crosslinker exchange, which can limit network reprocessability due to catalyst leaching and degradation. In this study, catalysts were avoided by using a bicyclo[3.3.1]nonane (BCN) bis-alkyl halide cross-linker with sulfur- atom neighboring group participation (NGP) to increase the rate of bond exchange. Stress relaxation analyses demonstrate that the resultant pyridine-based network has an Arrhenius dependence on viscous flow at elevated temperatures (130–170 °C), which arises from SN1 transalkylation exchange. This thermally mediated crosslink interchange and associated flow behavior enabled reprocessing of the ionic networks over multiple damage and repair cycles. Additionally, these NGP-based CANs are chemically recyclable, allowing for recovery of the pyridyl-based polymer starting material, which comprises > 90 wt% of the parent network. The dual thermal and chemical recycling potential of this catalyst-free CAN platform addresses key criteria for designing thermosets with extended lifecycles.

"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.

"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 nanoplateletswere 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.
