摘要

在高分子材料中，表面特殊潤濕性對於材料應用非常重要。本研究著重於高分子複合材料表面親疏水特性之探討。本研究內容主要分為兩大主題：
1. Tannic acid(TA)/ Polyvinylpyrrolidone (PVP) 高分子複合薄膜
本實驗使用TA與PVP於不銹鋼網上製備出環境友善且低毒性的 TA/PVP 高分子複合薄膜。改質後的不銹鋼網具有超親水特性並可成功應用於油/水分離，經過長時間連續分離測試後分離效果佳且流速穩定。此外此複合薄膜亦可應用於水下油滴的傳遞與收集。
2. Polybenzoxazine(PBZ)/奈米碳管(Carbon Nanotube)複合薄膜
本實驗將主鏈型Polybenzoxazine,(P(B-oda))與奈米碳管(Carbon Nanotube, CNT)混成，並加熱進一步交聯，成功製備出具有超疏水特性的P(B-oda)/CNT複合薄膜。針對製程中不同分散方式對成膜性的影響進行研究，並探討磨損、UV光照射等各種嚴苛實驗是否對複合薄膜表面潤濕產生影響。

Wettabilities are highly desirable properties for polymer materials that are used in a wide range of applications. This study includes two subjects and describes as follows, respectively:
1. Fabrication of Tannic acid (TA)/ Polyvinylpyrrolidone (PVP) composite for oil/water separation.
We describe simple methods for fabricating superhydrophilic TA/PVP composite coated stainless-steel mesh. The superhydrophilic meshes separate a range of oil/water mixtures effectively. Moreover, our superhydrophilic meshes also could be used for underwater oil transportation and collection.
2. Preparation durable superhydrophobic surfaces from carbon nanotube (CNT) and main-chain type polybenzoxazine (PBZ).
We report a simple method to prepare a robust superhydrophobic coating from CNT and main-chain type PBZ. The CNT/polymer coatings maintain their superhydrophobicity after abrasion, tape-peeling, and ultraviolet irradiation and display excellent environmental stability.
