Textile and industrial fibers respond to the environment according to their chemical composition and microstructure. Since fibers are typically semi-crystalline, they are generally more stable to both chemical attack and temperature then are wholly amorphous linear polymers. Polymer fibers are very good; indeed, they are the material of choice in some applications, yet they perform poorly in other environment. For example, polyolefins are virtually inert to inorganic, making polyolefin fibers useful as battery separator; however, polyolefins, like most other polymers, do not resist degradation in ultraviolet light. Consequently, polyolefin tent fabric is stabilized so that it can tolerate long exposures to sunlight. We will probe into the cause of poor ultraviolet stability in polymers and discuss ways to stabilize fibers. 

Effects of Salinity and the Extent of Water on Supercritical CO2-Induced Phlogopite Dissolution and Secondary Mineral Formation

本論文所載的研究有兩個目的。

首先，我們試圖藉由參考病患與家屬、醫療管理人員與專家、社會關懷管理人員與專家、以及遠距照護系統的生產者與供應商等四個重要利害關係團體的不同看法，去鑑別、描繪與瞭解那些增進或阻礙社區中慢性疾病管理遠距照料系統實現與整合的因子。
