Under the background of college entrance examination reform, it becomes imperative to improve the students' interest in chemistry. During the effort to investigate how to present the chemistry knowledge, to cultivate and promote students' interest and professional attitude towards chemistry, we developed the public science education laboratory of College of Chemistry and Materials Science, Northwest University. In the current paper, we introduced the background of setting-up, the missions and targets of the laboratory, as well discussed the construction, evaluation systems and prospection of the laboratory. 相似文献

采用饥饿法将2-甲基丙烯酰氧乙基磷酰胆碱(MPC)分别与甲基丙烯酸十八烷基酯(SMA)、 甲基丙烯酸十二烷基酯(LMA)及甲基丙烯酸正丁酯(BMA)聚合, 通过改变投料比例和沉淀剂种类, 合成了一系列含磷酰胆碱基团的仿细胞膜结构的两亲性二元随机共聚物. 1H NMR和元素分析结果表明, 合成的两亲性二元随机共聚物的组成与投料比相近. DSC结果表明, 聚合物具有较低的玻璃化转变温度. 表面张力及水的动态接触角(DCA)研究发现, 聚合物涂层表面具有明显的两亲性及表面结构易变性, 在空气中憎水基团在表面取向, 在水环境中亲水的磷酰胆碱基团则迁移取向到涂层表面形成仿细胞外层膜结构界面, 最终形成不溶于水的仿细胞膜结构涂层. 相似文献
