摘要：将叠氮基与碳纳米管(CNT)反应,制备叠氮化碳纳米管(ACNT),用FTIR、XPS等手段证明碳纳米管实现了叠氮化;借助超声波的作用使ACNT均匀分散于单体中,然后用原位聚合方法制备了聚三唑/碳纳米管(PTA/ACNT)复合材料。用透射电镜观察ACNT在基体树脂中的分散状况和复合材料的微观结构,研究了ACNT的添加分数对PTA/ACNT复合材料玻璃化温度(Tg)、热稳定性(Td5)和导热系数(λ)的影响。结果表明:与PTA纯树脂相比,当ACNT添加分数为1.0%(质量分数,下同)时,复合材料的Tg提高了33℃,在氮气中Td5提高了15℃,在空气中Td5提高了8℃;当ACNT添加分数为5.0%时,复合材料30℃的λ提高了45%,150℃的λ提高了30%。
Azido-carbon nanotube(ACNT) was prepared by the reaction of azide group with carbon nanotube(CNT). The azidation of CNT was proved by FTIR, XPS and so on. Under the effect of ultrasonic wave, ACNT was uniformly dispersed into monomers of polytriazole(PTA), and then PTA/ACNT composites were prepared via in situ polymerization. The dispersion status of ACNT in the matrix resin and the microstructure of PTA/ACNT composites were observed by TEM. The influence of ACNT addition on glass transition temperature(Tg), thermostability parameter(Td5) and thermal conductivity(λ) of PTA/ACNT composites were also examined. The results showed that in comparison with the blank PTA resin,Tgincreased 33℃, Td5increased 15℃ in nitrogen atmosphere and 8℃ in air for the PTA/ACNT composite with 1.0% ACNT; while λ increased by 45% at 30℃ and 30% at 150℃ for the PTA/ACNT composite with5.0% ACNT.
