| 中文摘要 | 臺灣為亞熱帶海島型氣候,常年高溫 (20~26℃) 多濕 (75~98% RH),基此,本研究旨在探討應用聚對二甲苯鍍膜技術進行脆弱紙質書籍和檔案之加固處理。由於對二甲苯單體的聚合反應在纖維間形成透明薄膜,且在聚合沉積過程中於纖維與纖維接觸點間形成高分子架橋,因此使得脆弱紙張之紙力得以增強。藉著聚對二甲苯鍍膜技術的應用,將可使書籍和檔案文物的耐久性獲得延長。試驗結果顯示:2種對二甲苯聚合物 (Parylene N and 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的功效。另對於紙張白度及顏色之改變並不顯著,以Parylene C造成色差增加程度較Parylene N為小。又其處理有助於提升紙張之抗濕潤性能 (接觸角增高),且Parylene C較Parylene N為優。採用5 μm之聚對二甲苯鍍膜處理對於Aspergillus niger, A. flavus, Penicillium sp., Rhizopus sp.,及Trichoderma viride等紙張常見黴菌具有抗菌性能,而Parylene C之抗黴性能優於Parylene N鍍膜處理者。 |
| 英文摘要 | In an effort to overcome the detrimental effects of a broad range of temperatures (20~36℃) and humidities (75~98% RH) throughout the year in Taiwan, we carried out this study to test the application of polyparaxylylenes known as Parylene in trade film coating technology for the preservation of brittle books and archives. The polymerization of the monomer paraxylylene formed a clear film on fibers that increased the paper strength (paper strengthening). During the deposition process, polyparaxylylenes formed polymer bridges at numerous fiber-to-fiber contact points, resulting in significant overall strengthening of the paper. The durability of books and archives was increased to some extent by this treatment. Experimental results showed that the folding endurance and zero span tensile strength of polyparaxylylene-treated papers improved markedly. Color changes of Parylene C-treated paper were less than those of the Parylene N-treated ones, but no significant difference was detected between the 2 treatments. A larger contact angle of Parylene C-treated paper indicated higher wettability resistance than that of Parylene N-treated paper. As might be expected, a 5-μm-thick polyparaxylylene conformal coating provided anti-fungal characteristics to such fungal strains, as Aspergillus niger, A. flavus, Penicillium sp., Rhizopus sp., and Trichoderma viride. Parylene C-treated papers had better fungal resistance than the Parylene N- treated ones. Generally speaking, the type, structure and physical characteristics of the papers influenced the end products when using polyparaxylylene. For a parylene film of constant thickness, different types of paper produced different end products. So while improvements occurred, the degree of improvement was dependent on those factors. |
