摘要

本研究利用無乳化劑乳化聚合法於沸騰環境下，製備均一粒徑之自交聯次微米球，並將此次微米球建構具機械性質之光子晶體薄膜。藉由添加自交聯劑(SCA)於次微米球中，使次微米球上之官能性基團與鄰近球間發生自交聯反應而穩定光子晶體結晶結構，得到具機械性質之光子晶體薄膜。
　　高玻璃轉移溫度之P(St-co-SCA)、P(St-co-MAA)/P(St-co-SCA)次微米球之研究中，由於SAC透過自交聯反應，仍無法提供球與球之間連結作用力，使光子晶體薄膜不具機械性質。
　　另一方面，為了提升光子晶體薄膜之機械性質，製備具低玻璃轉移溫度之P(BMA-co-SCA)、P(BMA-co-MAA)/P(BMA-co-SCA)及P(BA-co-MAA)/P(BA-co-SCA)次微米球。此一系列具低玻璃轉移溫度之次微米球透過自組裝程序，可得到具機械性質之光子晶體薄膜。

In this study, monodisperse self-crosslinking submicrospheres were prepared by soap-free emulsion polymerization at boiling state. The self-crosslinking submicrospheres were prepared by self-crosslinking agent (SAC) in the submicrospheres.
　　P(St-co-SCA) and P(St-co-MAA) /P(St-co-SCA) submicrospheres were prepared. But photonic crystals film with mechanical property wasn’t obtained by these self-crosslinking submicrospheres.
　　On the other hand, photonic crystals film with the mechanical property were obtained by using P(BMA-co-SCA), P(BMA-co-MAA)/P(BMA-co-SCA) and P(BA-co-MAA)/P(BA-co-SCA) submicrospheres.
