應用高分子鍍膜處理進行脆弱檔案紙質之加固

採用對二甲苯聚合物進行紙質文物加固處理，為新近圖書、檔案等文物保護之新應用技術。本研究在於探討各類紙張之對二甲苯聚合物鍍膜理想厚度，以求獲得良好之紙樣加固條件，評估聚合物加固處理紙樣之人工促進劣化及抗黴性能，期能提供文物維護領域對於紙質檔案文物大量加固處理的另一種選擇。研究結果顯示：對二甲苯聚合物（Parylene N, Parylene C）鍍膜處理對於紙張耐摺與零跨距強度之提升有相當顯著之功效。鍍膜處理對於紙張白度及顏色之改變並不顯著。聚對二甲苯鍍膜處理有助於提升紙張之抗濕潤性能（接觸角增高）。採用5 μm之聚對二甲苯鍍膜處理對於Aspergillus niger，Aspergillus flavus，Penicillium sp.，Rhizopus sp.，Trichoderma viride等紙張黴菌具有抗菌性能，而C型對二甲苯聚合物之抗黴性能優於N型對二甲苯聚合物鍍膜處理者。

The application of polyparaxylylenes coating technique to the paper strengthening is a newly developed one for books and archives protection. The principle of paper strengthening is that when the monomers of paraxylylenes polymerize into a clear film on paper fibers, during the deposition process the paraxylylenes will form polymer bridges at the numerous fiber-to-fiber contact points, resulting in a significant overall strengthening of the papers. It would increase the durability of books and archives remarkably. The experimental results indicate that the folding strength and zero span strength of papers increase remarkably after being treated with the coating of polyparaxylylenes. The color change induced by Parylene C is less than that of Parylene N, and both changes are not significant. The humidity resistance of coated papers increases after using parylene coating, and the use of Parylene C is superior to that of Parylene N. The conformal coating thickness of 5 μm-polyparaxylylenes generates anti -fungal characteristics to fungi such as: Aspergillus niger, Aspergillus flavus, Penicillium sp., Rhizopus sp. and Trichoderma viride, and the fungal resistance of Parylene C coated paper is better than that of Parylene N coated paper.
