摘要

本研究首先將Poly(vinylidene fluoride)(PVDF) 以化學鍵結接至碳奈米管表面，並證實此接枝之反應產物，可以繼續進行原子轉移自由基聚合反應，而將親水性高分子Poly(sulfobetaine methacrylate) (PSBMA) 與Poly(ethylene glycol)methacrylate (PPEGMA)反應至碳奈米管上，以全反射式傅利葉轉換紅外線光譜分析儀(Attenuated Total Reflectance-Fourier Transform Infrared Spectrometer，FTIR-ATR)、熱重損失分析儀(Thermal Gravimetric Analysis，TGA)、化學分析電子能譜儀(electron spectroscopy for chemical analysis，ESCA)及高解析穿透式電子顯微鏡（ High Resolution Transmission Electron Microscopy， TEM)鑑定所合成兩性高分子改質的碳奈米管。隨後將所製備之奈米混成材料掺混至PVDF 高分子中，製備成奈米複合膜材，以介質分析儀、水接觸角量測儀等量測所製得之複合膜材。改質後的材料由表面水接觸角與表面吸水性的測試後， 其與未改質的PVDF 材料相較下， 改質後的CNT-PVDF-PPEGMA 及CNT-PVDF-PSBMA 高分子奈米複合膜材，其親水性有10-20%的提升，顯示在改質材料表面的成份與型態皆已符合接枝高分子性質，由以上測試確定將材料成功改質。

In this study, poly(vinylidene difluoride) (PVDF) chains have been covalently bonded to multiwalled carbon nanotubes (MWNTs) through atom transfer radical polymerization. The obtained MWNT-PVDF nanohybrids could used as
macro-initiators of ATRP for further polymerization of sulfobetain methacrylate
(SBMA) and poly(ethyleneglycol)methacrylate (PEGMA). The prepared amphiphilic-polymer-functionalized MWNTs have been characterized with Fourier Transform Infrared Spectroscopy, electron spectroscopy for chemical analysis,
thermogravimetric analyzer, and high-resolution transmission electron microscopy.
The prepared amphiphilic-polymer-functionalized MWNTs have been utilized as nano-modifiers for preparation of PVDF/MWNT nanocomposites. Addition of modified MWNTs to PVDF enhances their mechanical properties and surface
hydrophilicity. The PVDF/MWNT nanocomposites are potentially applicable for protein-resistant materials.
