【摘要】 为进一步深化实验教学改革,培养学生的综合能力、实践能力、创新能力和科研探索精神,开设了由教师科研项目转化而来的设计性实验。介绍了聚电解质复合纳滤膜的制备及性能测试的原理和方法。学生可根据自己的思路选择不同的聚电解质,制备出不同的聚电解质复合纳滤膜。通过对膜性能的测试,初步了解聚电解质种类、聚电解质层数、组装顺序等对膜性能的影响。更多还原

【Abstract】 To deepen the reform of the experimental teaching,and cultivate students’ abilities of synthesis,practice,creativity and explorative spirit in scientific research,a designing experiment on polyelectrolyte composite nanofiltration membranes was introduced,and the experimental design approach and principle were depicted.Students can choose different polyelectrolyte according to their own ideas,and different composite nanofiltration membranes would be prepared.The influence of assembling conditions,such as polyelectrolyte types,polyelectrolyte layers,sequence of polyelectrolyte layer and so on,on the performance of membranes was investigated by performance test.更多还原
