| 摘要: | 本研究以三異氰酸單體為殼材,幾丁聚醣( chitosan)為核心材,採用原位 直接聚合法製備PU系微膠囊,並將所製得之微膠囊定量塗佈於水軋布上。 藉由改變攪拌轉速製造出粒徑大小不同之微膠囊,探討微膠囊粒徑的大小、 微膠囊濃度的不同與膜材量的多寡對水軋布抗菌效果之影響。結果顯示,粒徑大小的改變對抗菌效果無顯著影響,而微膠囊添加的濃度對抗菌有顯著的效果,膜材的多寡對抗菌效果無顯著的影響。
The study aim at PU material microcapsules by In-Situ Polymerization which were prepared fonn PU as wall material, chitosan as core material, and coating on the water-mangle fabrics by control the weight. The particle size of microcapsules and the evaluation of antimicrobial effects by change stirring speed, concentration of microcapsules and weight of the wall material. The experimental results showed that changed the stirring speed were not affected the antimicrobial effects, increase concentration of microcapsules affected the antimicrobial effects and change the weight of wall material were not affected the antimicrobial effects. |
