In this talk, Chya-Yan will share several research projects she conducted during her PhD and postdoctoral studies. These include the selfassembly behavior of block copolymers in selective solvents, where she utilized theoretical calculations and experimental methods to validate the morphological transformations of micelles under different temperatures and concentrations. Secondly, she will discuss how operational parameters during the FFF 3D printing process influence the interlayer bonding strength of high-performance and crystalline polymers—an often overlooked topic, yet crucial for the future applications of 3Dprinted materials. Finally, Chya-Yan will introduce her development of 3D-printable hydrogel inks capable of forming wrinkling patterns with user-defined and spatially controlled geometries when exposed to water. This versatile approach holds significant potential for fabricating a wide range of devices.
