采用原子转移自由基聚合(ATRP)法聚合甲基烯丙基聚氧乙烯醚(HPEG)和丙烯酸甲酯(PMA),生成低分子量梳形结构的低聚物HPEG/PMA.经Fourier红外光谱(FT-IR)和核磁共振氢谱(1 H NMR)对其结构特征基团进行分析,确认合成了目标产物.对HPEG/PMA进行凝胶渗透色谱(GPC)测试,结果表明,ATRP法制备的梳形HPEG/PMA分子量为7.7×103,分布系数为1.11,具有优异的可控性.梳形HPEG/PMA经V(乙醇)∶V(水)=1的NaOH溶液水解,得到梳形结构甲基烯丙基聚氧乙烯醚和丙烯酸(HPEG/PAA)低聚物.
The patterning adsorption of the polyethylene oligomer(PE) on the side-wall of carbon nanotubes(CNTs) composed of CNT(5,5),CNT(10,0) and heterojunction was researched using the classical molecular dynamic simulation.The configuration of the PE chains on the side-wall of the CNTs depended on the dimensional matching of PE and CNT mostly.The patterning adsorption was presented when the length of the PE chains and the pure CNT part matched.
