贻贝,普遍存在于沿岸和近海,是甲壳类软体动物。贻贝具有黏附蛋白,表现出超强粘附能力,从而引发了广泛的研究兴趣。研究结果表明儿茶酚基团是贻贝蛋白具有超强粘附性的关键性组分。受自然界启发,目前已经有较多文献报道了含儿茶酚基团的仿贻贝聚合物。总结这些文献可以发现,当前所报道的儿茶酚功能化聚合物(catechol-functionalized polymers)的结构主要有封端聚合物、无规共聚物、接枝共聚物和嵌段共聚物,交替共聚物结构未见报道。另外要制备这些聚合物,儿茶酚往往需要先通过化学修饰在其中引入可聚合物的双键基团,形成双键化的儿茶酚单体;而且这些聚合物的儿茶酚含量往往比较低,其摩尔含量一般低于30%。
上海交通大学化学化工学院周永丰教授课题组合成了第一例仿贻贝的多巴胺交替共聚物P(DA-a-BGEPF)。不用对多巴胺做任何处理,在弱碱性条件下,直接通过多巴胺的胺基和双环氧单体中环氧基团的点击反应,一步制备了多巴胺交替共聚物,该合成过程方便、简便,而且所制备的聚合物中儿茶酚的摩尔含量高达50%。该工作已经发表在Chinese Journal of Polymer Science (2018) “Rapid Communications”栏目,第一作者硕士生张颖琳
在本报道中,作者还发现所制备的P(DA-a-BGEPF)交替共聚物可以在DMF/H2O溶液中自组装形成结构规整的纳米小球,球的尺寸约为550 nm。通过儿茶酚基团与铁离子之间的络合可以实现小球的交联,在空气中高温焙烧后,进一步得到N和C掺杂的α-Fe2O3小球(α-Fe2O3@CN)。 α-Fe2O3@CN小球尺寸约为150 nm,可以直接用作锂离子电池的负极材料,在0.2 C充放电循环100圈后,可逆容量可稳定在1134 mA·h·g-1,并具有优秀的循环稳定性和良好的倍率性能,其电化学性能和文献已报道的最好的α-Fe2O3负极材料相一致。

6月19日,由校办、教务处、学工部主办,华东理工大学材料学院承办的第三十七期“通海讲堂”在奉贤校区举行。国家“杰青”、科技部“万人计划”领军人才、上海交通大学特聘教授周永丰应邀为我校师生做了题为“化学与生活”的精彩讲座,以相对科普的方法介绍当代化学研究领域的特点和趋势。我校材料学院副院长李欣欣教授出席并主持讲座。


讲座中,周永丰首先从同学们生活中常见的化学现象开始,到大学操作过的基础化学实验,再进一步到微观分子层面的变化展示,提出了“为什么会有这些变化现象?”,“化学的奥秘又是什么?”等问题。他解释道,化学是研究物质之间相互作用的科学,也是创造新物质的重要手段和方法,是人类用以认识和改造物质世界的主要方法和手段之一,以化学为基础可以延伸出许多方向的新发展。同时,作为化学研究者,周永丰感到十分自豪的是化学领域虽不像当今信息工程如此热门,但它是一门从不会冷门的学科。


随后,周永丰采用了相对科普的方法介绍当代化学的研究内容和前沿趋势,包括化学与健康、化学与能源、化学与环境、3D打印等方面,并通过从与绿色能源相关的太阳能电池材料到与生命科学相关的3D打印人体器官等例子来阐述目前化学领域所面临的难题和挑战。此外,依据目前化学领域的发展方向和进程,周永丰为同学们描绘出未来的能源、环境、生命医学等方向的发展形势。他表示希望通过此次讲座能进一步拓展同学们的化学和化工类学生的知识面,有利于同学们比较全面和准确的认识化学学科,了解化学学科的未来发展趋势。接着,周永丰和同学们设想了如果生活没有化学,会发生哪些变化,并借此再次强调,化学在人类生活中无处不在。


在学生提问交流环节,周永丰就学科发展方向、读研深造等疑问进行了耐心细致的解答。他首先肯定了在这门学科继续读研深造的必要性,并且指出讲座中所提到一些化学学科发展方向都有可能是同学们未来在毕设、研究生课题中能接触到的研究热点。在这些研究方向仍存在许多问题亟待解决,他期望同学们未来能在这些领域中迎接挑战、突破创新。


讲座最后,李欣欣代表在场的师生对周永丰表示感谢,也肯定了现代文明以及人类日常生活与化学密切相关,并总结道,在拥有先进技术的今天,科研工作者们仍须努力奋斗,创造更美好的明天。
