Latest Patents

Yijia Ma's latest patents include two groundbreaking methods. The first patent, titled "Recovery and reuse of acid digested amine/epoxy-based composite matrices," outlines a method for recycling matrix residues. This method involves degrading a target epoxy to form matrix residues, collecting these residues, and incorporating them into a polymer-forming formulation. The formulation is characterized by the inclusion of multifunctional anhydride monomers and polyfunctional co-reactant monomers.

The second patent, "Aerobic depolymerization of fiber-reinforced composites," presents a method for the aerobic depolymerization of fiber-reinforced polymer (FRP) composites using sustainable reagents and conditions. This innovative approach allows for the digestion of a cured matrix into soluble monomers and oligomers through catalytic aerobic oxidation. The process enables the removal of carbon fibers for reuse, while the remaining material is treated to isolate valuable monomers. These isolated monomers can then be converted back into resin precursors for further use, addressing the challenges posed by the typically irreversible cure reaction that hinders recycling of FRP composites.
