Description
技术领域
本发明涉及高分子材料技术领域，具体为一种聚丙烯与石墨烯复合导电功能材料及其制备方法。
背景技术
聚丙烯是一种半结晶的热塑性塑料，密度为0.90g/cm3，是最轻的通用塑料，具有无毒、无味、密度小、优良抗吸湿性、抗多种有机溶剂和酸碱腐蚀等优点，广泛应用于汽车工业、家用电器、管材、机械零件制作等方面。缺点是耐低温冲击性差，较易老化，但可分别通过改性和添加抗氧剂予以克服。但是聚丙烯材料由于绝缘好，表面电阻率大于1014Ω，容易在表面积聚电荷，形成静电，静电累积后易伤人或者造成其他损失。因此，通过改性降低聚丙烯表面累积静电是扩大其应用范围的重要途径。
石墨烯是一种二维碳材料，是单层石墨烯、双层石墨烯和多层石墨烯的统称，于2004年问世，其发现者是英国曼彻斯特大学安德烈-海姆教授，2010 年获得诺贝尔物理学奖。石墨烯是新一代的透明导电材料，它几乎是完全透明的，厚度仅一个原子层。常温下其电子迁移率超过15000cm2/V·s，又比纳米碳管或硅晶体高，而体积电阻率只约1Ω·m，比铜或银更低，为世上电阻率最小的材料。因其电阻率极低，电子迁移的速度极快，因此被期待可用来发展更薄、导电速度更快的新一代电子元件或晶体管。由于石墨烯实质上是一种透明、良好的导体，也适合用来制造透明触控屏幕、光板、甚至是太阳能电池。石墨烯作为一种新兴的碳材料，由于具有较大的比表面积，高导电性和超高机械强度等特点，被认为是最理想的增强材料。将石墨烯与聚合物复合可以提高聚合物的力学性能、电学性能和热稳定性等，得到密度小、强度高、导电性能良好的新型材料。
石墨烯表面能较大，层与层之间具有较强的π-π共轭作用导致相互吸附，并且不能溶于水和一般有机溶剂中，因此很难与聚合物基体形成有效的相互作用，难以分散，这些问题极大的限制了石墨烯的应用。
