| Summary: | 碩士 === 國立中央大學 === 化學工程與材料工程學系 === 103 === In this study, monodispersed core-shell submicrospheres were prepared by two-step soap-free emulsion polymerization at boiling state. Hard core provided crystalline ability that maintain periodic array. On the other hand, soft shell as the role of adhesive between particles that improved film-forming property of photonic crystal(PC).
The monodispersed core-shell submicrospheres were PS/PBA, PS/PBMA, PS/P(BA-co-SCA), PS/P(BA-co-SCA-co-DVB), P(St-co-MMA-co-DVB)/P(BA-co-SCA),P(St-co-MMA-co-DVB)/P(BMA-co-SCA).
The core-shell structure submicrospheres were obtained by introducing SCA (Self-crosslinking agent). So, PC could exhibit structure colors by these submicrospheres. Photonic bandgap were improved by appropriate amount of SCA which could increase regular arrangement by functional force interparticles. Moreover, functional groups of SCA were further reacted by self-condensation to form network structure to improve the mechanical strength and solvent-resistance properties of PC.
