摘要
通过溶液回流法制备α-磷酸锆(α-ZrP),并采用四丁基氢氧化铵(TBA)在丙酮中对α-ZrP进行剥离。苯并噁嗪单体在剥离态α-磷酸锆[α-ZrP(TBA)]存在的条件下原位开环聚合后,制备了苯并噁嗪树脂(PBa)/α-ZrP(TBA)纳米复合材料。通过透射电子显微镜表征了α-ZrP(TBA)在PBa中的分散状态,采用热重分析法研究了PBa/α-ZrP(TBA)纳米复合材料的热性能。结果表明,剥离态α-磷酸锆呈纳米状态均匀分散在PBa基体中,并可有效提高PBa的高温残留量。加入5% α-ZrP(TBA)的PBa纳米复合材料具有最佳成炭能力。
α-Zirconium phosphate (α-ZrP) was synthesized using the solution reflux method and it was exfoliated by tetrabutylammonium hydroxide ( TBA ) in acetone. Furthermore, polybenzoxazine nanocomposites [ PBa/α-ZrP (TBA)] were prepared through the in-situ ring-opening polymerization of benzoxazine monomers at the presence of exfoliated α-ZrP. Transmission electron microscope (TEM) was used to measure the dispersion state of the exfoliated α-ZrP in PBa matrix. The thermal properties of PBa/α- ZrP(TBA) composites were studied through thermogravimetric analysis (TGA). The results demonstrate that the exfoliated α-ZrP in nano-state is dispersed in PBa matrix uniformly. Meanwhile, the exfoliated α-ZrP could promote the amount of char at high temperature effectively. The PBa/α-ZrP-5 % (TBA) nanocomposites with the 5% α-ZrP(TBA) addition have the best charring ability.
