以聚醚砜(PES)为原料,1-甲基-2-吡咯烷酮(NMP)为溶剂,氧化石墨烯(GO)为填充剂,采用静电纺丝技术成功制备GO/PES复合纤维膜。结果表明,当GO添加量为0.2%(质量分数)时,复合纤维膜拉伸强度为2.55MPa,弹性模量为23.88MPa,断裂伸长率为49.78%,电导率达到2.74×10-7S/m,比未添加GO的纤维膜提高了4个数量级。
The graphene oxide/polyethersulfone fiber membrane was successfully prepared by electrospinning with 1-methyl-2-pyrrolidone (NMP) as solvent.When graphene oxide content was 0.2%,the tensile strength of membrane was 2.55MPa,the elasticity modulus was 23.88MPa,the elongation at break was 49.78%, electrical conductivity was 2.74×10-7S/m which was 4 orders higher than that of pure polyethersulfone fiber membrane.
