Outline of Final Research Achievements

To create ionic liquid-based gels and porous polymers, the PI incorporated an ionic liquid as a solvent into the thiol-ene network of thiol-based multifunctional monomers and acrylate crosslinkers via a one-step polymerization process. This approach enabled precise manipulation of polymerization conditions and solvents, resulting in the careful design of gels and porous polymers with tailored properties. Utilizing fused filament fabrication (FFF) technology, the PI improved capabilities in creating precise and intricate molds with excellent dimensional accuracy. Diversifying the printing methods underscores our commitment to innovation and continuous improvement.Overall, this plan aligns with our objective of advancing manufacturing processes through innovation. The developed materials exhibited excellent piezo-capacitive sensing characteristics, allowing them to detect mechanical pressure and convert it into electrical signals.
