科研成果向教学资源转化一例——麦饭石复合高吸水树脂合成

A Case of Scientific Research into Teaching Resources——Preparation of Maifan Stone/PAA Super Absorbent Composites

为了使学生了解高吸水树脂的研究开发趋势,培养学生的创新能力,结合近年来的科研成果,在多次实践检验的基础上,推荐了一个新的高分子化学实验-麦饭石复合高吸水树脂合成。利用溶液聚合的方法合成麦饭石复合高吸水树脂,在实验过程中通过改变丙烯酸的浓度及中和度,交联剂、引发剂、麦饭石的用量来反映各种因素对树脂吸水倍率的影响。通过将科研成果转化为教学资源,开阔了学生的视野,提高了教育教学质量。

In order to make the students understand the research and development trend of high water- absorbing resin,and develop the students＇ innovation ability,combining with the scientific research achievements of recent years and the basis of the practice for many times,a new polymer chemistry experiment was recommended. Maifan stone composite high water- absorbing resin was synthesized by solution polymerization,changing the concentration of acrylic acid and neutralization degree,the dosage of the crosslinking agent,initiator and Maifan stone,to reflect the influence of various factors on the water absorption rate. Through the scientific research into teaching resources appropriately,the student＇s field of vision was opened and the education quality was improved.
