Buckypaper/聚合物复合材料中碳纳米管团聚较少,且含量较高,使得碳纳米管的优异性能得以更加充分的发挥,显著提升了复合材料的各项性能.由于Buckypaper结构紧密,传统的滤渗浸渍方法不能满足制备高质量Buckypaper/环氧复合材料的要求.为提高环氧树脂在Buckypaper中的浸渍效率和质量,开发了Buckypaper的“加压滤渗”浸渍工艺,将环氧树脂溶液通过Buckypaper进行加压过滤,实现对Buckypaper的有效、均匀和完全浸渍.Buckypaper/环氧复合材料微观形貌表征结果表明,“加压滤渗”浸渍工艺制备的Buckypaper/环氧复合材料表面质量良好,且环氧树脂在Buckypaper内部充分浸渍,且分布均匀.与溶液浸渍法制备的Buckypaper/环氧复合材料对比,“加压滤渗”浸渍工艺制备的复合材料具有更加优异的力学性能,更加充分地发挥了Buckypaper的增强效率.
