1、水溶性導(dǎo)電型涂料的制備及性能研究作者：XXX指導(dǎo)老師：XXX摘要在非極性有機(jī)溶劑—功能質(zhì)子酸—水三相體系中，以十二烷基苯磺酸(DBSA)為乳化劑，十二烷基苯磺酸和鹽酸為摻雜劑，過(guò)硫酸銨(APS)為氧化劑，采用乳液聚合法制備水溶性導(dǎo)電聚苯胺(PANI)，研究了摻雜劑配比、氧化劑量、攪拌時(shí)間、反應(yīng)溫度對(duì)聚苯胺的電導(dǎo)率和溶解度的影響。綜合考慮電導(dǎo)率和溶解度兩者性能，確定最佳反應(yīng)條件為：反應(yīng)溫度15℃，攪拌時(shí)間3h，n(苯胺)：n(HCI)：n(DBSA)：n(APS)=0.050:0.100:0.006:0.050，此時(shí)產(chǎn)物的電導(dǎo)率為3．95S·cm-1，溶解度為21．
2、86％。此時(shí)的產(chǎn)物在水中有良好的分散性能，能夠與水性高分子樹(shù)脂進(jìn)行共混加工。紅外光譜表明，摻雜態(tài)聚苯胺的特征吸收峰都向低頻方向移動(dòng)，苯醌結(jié)構(gòu)的吸收峰發(fā)生了較大的變化，這說(shuō)明聚苯胺的摻雜部位發(fā)生在苯醌結(jié)構(gòu)上；紫外光譜表明，代表苯醌上電子躍遷的峰發(fā)生了明顯的移動(dòng)。關(guān)鍵詞：聚苯胺；電導(dǎo)率；溶解度；共摻雜31Water-solubleconductivecoatingsPreparationandPropertiesstudyAuthor:XXXInstructor:XXXAbstractTheWater-solubleconductivepolyanilinewassy
