简介：Poly(methylmetacrylate)(PMMA)/Y0.0025Si0.025Ba0.9725(Ti(0.9)Sn0.1)O3(YBTS)composites在YBTS的不同重量比率被准备(0wt%，5wt%，10wt%和20wt%YBTS)招待以便在PMMA的电、光的性质上调查YBTS增加的效果。电的性质(阻抗，绝缘的经常的绝缘的损失和交流电导率)在频率范围被学习10kHz-1MHz并且在温度范围20鈥?0掳C。在增加YBTS的内容之上陶器，我们在在绝缘的经常的、绝缘的损失和PMMA的交流电导率的阻抗和增加观察了减小主人。我们也发现在高YBTS内容的松驰过程由于在离子的传导性的松驰。吸收系数(伪)在波长范围被决定了230鈥?在为所有YBTS-PMMAcomposites的房间温度的00nm。而且，YBTS的增加陶器高度特别在300nm下面提高PMMA主人的紫外吸收。对PMMA主人陶器的20wt%YBTS的增加减少从5eV的光精力差距到3.41eV。关联在之间电，光并且SEM结果被报导。关键词电-光-PMMA，陶器-铁电体-Composites

简介：由形成毛孔的代理人聚乙烯乙二醇(木钉)组成的各种各样的贯穿半的聚合物网络(semi-IPN)hydrogels，丙烯酸的酸(AA)和acrylamide(AM)被与一个二拍子的圆舞方法使用免费激进的聚合准备。综合hydrogels的化学结构被FTIR光谱学描绘，形态学被扫描电子显微镜学(SEM)学习方法。胀大的性质例如pH应答的行为，腌敏感，在有各种各样的pH价值的不同答案的摆动的swelling/de-swelling行为和在洗澡pH振荡器的自我震荡的行为详细被调查。当pH从3.0和7.0并且很好中等变化珍视时，结果表明准备hydrogels展出了高pH敏感和优秀的盐敏感由经历很多swelling/de-swelling的可逆性质再循环。特别地，hydrogels在包含兄弟的一个封闭系统展出了自激振荡行为3那么32Fe(CN)64H+。这研究可以为新自我走的致动器和另外的设备作为biomaterial创造新可能性。
