一般描述

聚(丙烯酸)(PAA)本身具有吸湿性和脆性,无色,Tg接近106oC。在200-250oC温度下,它会脱水变成不溶的交联聚合物酸酐。干燥PAA在水中的溶解度随着温度升高而增加。浓的PAA水溶液本质上是触变性的。

应用

PAA可用于制备纳米羟磷灰石聚丙烯酸(Hap/PAAc)生物复合材料。†PAA的其他潜在应用: 研究聚乙烯醇/PAA共聚物水凝胶中的溶质扩散†,合成聚(N-异丙基丙烯酰胺)-嵌段-PAA共聚物,它对温度和pH刺激都有反应†,制备低聚(甲基丙烯酸甲酯)/PAA嵌段共聚物,用于胶束递送疏水性药物†,以及作为粘合剂的增稠剂。

Phyllosilicate Clay Minerals: Principles and Applications

We have discussed shortly the applications of 1:1 and 2:1 phyllosilicate material in membrane technology, as well as the basic geometric understanding of their layered structures.

Magnetic-Plasmonic Hybrid Nanobeads Designed for Imaging and Isolation of Cellular Organelles

Magnetic-plasmonic nanoparticles offer the combined benefits of both a magnetic probe as well as additional imaging modes usually associated with noble metal nanoparticles. Professor Shinya Maenosono (Japan Advanced Institute of Science and Technology) explores the synthesis, characterization, and proof-of-concept application of Ag/FeCo/Ag core/shell/shell magnetic-plasmonic nanobeads for imaging and isolation of cellular organelles (autophagosomes of COS-1 cells).
