摘要:
为了改善水性环氧树脂(Waterborne epoxy, WEP)的力学性能及丰富其驱动形式,首先合成了具有优异的光热性能的聚多巴胺(Polydopamine, PDA)纳米颗粒,然后将其添加到WEP基体中,制备PDA/WEP形状记忆复合材料,并通过一系列表征方法进行表征。结果表明:PDA纳米颗粒的添加能改善复合材料的力学强度,纯WEP的断裂强度为88 MPa,01 wt%PDA/WEP的断裂强度较纯WEP有明显的提高;PDA的加入赋予WEP光驱动性能,即使PDA含量仅为01 wt%,在808 nm的近红外光照射下,PDA/WEP复合材料的温度能在30 s内由室温(25 ℃)上升到104 ℃,且形状回复能在13 s内迅速完成,复合材料形状回复时间随PDA纳米颗粒含量增加而缩短。由于PDA纳米颗粒制备方法简单环保,且光热转换性能优异,具有作为功能填料制备光驱形状记忆聚合物复合材料的潜力。
