采用连续化学改性的方法合成聚苯乙烯接枝多壁纳米碳纳米管, 选择性地将聚合物链引入壁及其自组装通过各向异性斑块是提出.

该程序的总体目标是提供一种通过聚苯乙烯链接枝多壁碳纳米管的简单策略，这介导了促分子自组装和各向异性斑块。该方法有助于调节多壁碳纳米管的表面性能，从而在热塑性聚合物领域建立改进的加工条件。接枝策略为碳纳米管的加工方案提供了一种简单的替代方案，以便使其与工业相关但具有挑战性的聚合物（如聚苯乙烯）相容。

通常，该方法从原始碳纳米管侧壁上的传统羟基开始，然后是硅烷基化甲基丙烯酸基团与 OH 基团的偶联，以及它们在内部大气中与苯乙烯的连续自由基聚合。为了找到产量，用聚苯乙烯链接枝纳米管。该技术的主要优点是它可以很容易地部署到碳纳米管的摩尔表面特性。
