摘要:
采用芳叔胺基团对凹凸棒土(ATP)进行表面修饰制备改性粒子(ATP-ATA),通过表面引发氧化-还原聚合制备凹凸棒土接枝聚苯乙烯杂化粒子(ATP@PS),利用X射线衍射(XRD)、X射线光电子能谱(XPS)、热失重(TGA)、场发射扫描电镜(FESEM)和透射电镜(TEM)对杂化粒子进行详细表征。通过熔融共混法制备PS/ATP@PS杂化材料,并研究杂化粒子含量对材料力学性能、热稳定性和粘弹行为的影响。结果表明,杂化粒子质量比为1.5%时,材料的拉伸强度、冲击强度和弯曲强度分别提高65.5%,28.5%和25.3%,随杂化粒子含量增大,材料的热稳定性提高,粘流态下具有较大的线性粘弹区和更长的松弛时间。
Abstract:
Attapulgite(ATP)was firstly modified with aromatic tertiary amine(ATA)to afford functionalized particles ATP-ATA. Subsequently, ATP grafted with polystyrene hybrid particles(ATP@PS)were prepared via surface-initiated redox polymerization. The resulted hybrid particles were characterized by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), thermal gravimetric analysis(TGA), field-emission scanning electron microscopy(FESEM)and transmission electron microscopy(TEM). PS/ATP@PS hybrid material was prepared via melt blending technique, and the effects of particle contents on the mechanical property, thermal stability and viscoelastic behavior of hybrid materials were investigated in detail. Experimental results showed that as compared with pure PS, the tensile, impact and flexural strength with 1.5% content of ATP@PS increased by65.5%, 28.5% and 25.3%respectively. The thermal stability was enhanced as the increase of ATP@PS content, and broaderlinear viscoelastic region and longer relaxation time were observed in the viscous-flow state.
