摘要
通过原位聚合法制备改性的多壁碳纳米管和聚乙烯复合材料.讨论偶联剂对催化活性、复合材料力学性能等的影响.实验表明:经过酸化和偶联剂改性的多壁碳纳米管通过二次负载钛系活性可达2.0×103g/g.h左右,分子量为2.0×105左右,当复合材料中多壁碳纳米管质量分数达2.5%时拉伸强度可超过30 MPa.
Modified multiwalled carbon nanotubes （MWNTs）/polyethylene（PE） composites were prepared by in-situ polymerization. The effect of the coupling agent on catalyst activity and composites mechanical properties were disscussed. The results had showed that activity of multiwalled carbon nanotubes, which were treated by acid and modified by coupling agent respectively, then followed by twice support titanium, was about 2.0 × 10^3 g/（g·h）. The molecular weight of composites was about 2.0 × 10^5. When multiwalled carbon nanotubes content reaches 2.5 % in composites, the tensile strength was 30 MPa.
