基於氣相昇華與沉積製程建構聚對二甲苯為基底之執行元件

Abstract

聚對二甲苯以其眾多優點聞名。本研究在此介紹多樣性的聚對二甲苯型態。利用聚乙二醇在聚對二甲苯之薄膜上接合之方法，進行表面改質，提升其親水性。經由表面修飾後，聚對二甲苯薄膜將可能提升其生物相容性，及防止蛋白質在物質表面進貼附。此外，本文更進一步的將聚對二甲苯從傳統常見的二維薄膜型態轉化為三維的多孔塊材。並藉由調控傳送之氣體量多寡以及凍乾技術，構築出具有多層級架構的多孔複合材料。以此多層多孔的材料結構為基礎，添加氧化鐵，促使以聚對二甲苯為基底之執行元件可以被外界磁場所刺激，進而反映出特定的運動模式。這樣的技術，使聚對二甲苯的運用達到一個新的水平，同時也開啟了新的應用。

Poly-para-xylylene is well-known for its numerous advantages. Here, we introduce the diverse form of poly-para-xylylene. PEG conjugation on the polymer is used to change the surface characteristics of the parylene film, improving the reaction for parylene C film and hydrophilic substance that may raise the biocompatibility and antifouling in vivo. We take parylene one step further and convert it from a two-dimensional configuration of dense films to a three-dimensional bulk, porous substance. Based on the quantity of entrance gases and freeze-drying mechanism, the hierarchy porous composite was developed. On this bubble porous construction, iron powder is added to cause the parylene-based actuator could stimulate by an external magnetic field, performing a specific action. The technique takes parylene to a new level and opens up an advanced application.
