9月4日上午,Matthew Hill教授和Xavier Mulet教授应邀访问材料化学工程国家重点实验室,在科技创新大楼A506分别做了以“多孔材料近期进展:诱导释放和抗老化膜”和“利用金属有机骨架的仿生物矿化”为主题的学术报告。本次报告由材料化学工程国家重点实验室孙林兵教授主持,实验室部分教师和研究生参加了报告会。
第一场讲座中,Hill教授首先简单扼要地讲述了通过磁感应变压吸附的方法释放金属有机骨架材料中储存的分子,该方法克服了以往方法适用范围小、成本高的缺点,并且可以做到100%释放储存的分子;紧接着Hill教授又讲了随着时间的延长,聚合物的孔会变少,渗透性变差,这一聚合物的老化现象会阻碍其在分离气体混合物方面的应用,通过加入PAF材料可以解决这一问题,阻止聚合物的老化,提高其渗透性,保持其在分离气体混合物时的选择性。
第二场讲座中,Mulet教授介绍了MOFs材料在生物科技中的应用。他指出,提高功能化生物大分子的稳定性是生物科技中一个重要的挑战,如果这个问题得以解决,那么将改善功能化生物大分子在制药、化工过程以及生物储存方面的应用。报告着重介绍了用金属有机骨架材料包裹生物大分子的策略以提高其稳定性,展示了聚集骨架构架模块及金属有机骨架在生物大分子上的结晶。蛋白质、酶、DNA和细胞可以引发金属有机骨架保护层的形成,使得到的生物复合材料可以在许多生物大分子通常会分解的情况下稳定存在。
在场师生对Matthew Hill教授和Xavier Mulet教授的报告内容兴趣浓厚,众多老师和同学们也都相继提问和两位教授进行了热烈交流。
