【摘要】:采用細(xì)乳液聚合的方法制備不對稱粒子,并以聚苯胺乳液進(jìn)行雜化,形成納米導(dǎo)電不對稱粒子。研究了引發(fā)劑種類和第二單體投料方式對不對稱粒子的形貌和粒徑的影響,并使用透射電子顯微鏡和粒徑分析儀等對粒子進(jìn)行表征。結(jié)果表明,當(dāng)使用水溶性引發(fā)劑,第二單體以20 g×h~(-1)恒速滴加時,不對稱粒子特征明顯。使用聚苯胺乳液對不對稱粒子進(jìn)行改性,從而獲得導(dǎo)電納米材料。不對稱粒子乳液中雜化聚苯胺乳液會使得粒子粒徑變大;當(dāng)不對稱粒子和聚苯胺質(zhì)量用量比例1:1,不對稱粒子壓片后電導(dǎo)率會階段性升高。至此,由雜化方法成功制備了納米導(dǎo)電不對稱粒子。
[Abstract]:Asymmetric particles were prepared by microemulsion polymerization and were hybridized with Polyaniline emulsion to form nanometer conductive asymmetrical particles. The effects of initiator type and second monomer feeding mode on the morphology and particle size of asymmetric particles were studied. The particles were characterized by transmission electron microscopy (TEM) and particle size analyzer. The results show that when the water-soluble initiator is used and the second monomer is added at a constant rate of 20 g 脳 h ~ (- 1), the characteristic of the asymmetric particles is obvious. Conductive nano-materials were obtained by modifying asymmetric particles with Polyaniline emulsion. The hybrid Polyaniline emulsion in asymmetric particle emulsion can increase the particle size, and when the mass ratio of asymmetric particle to Polyaniline is 1? 1, the conductivity of asymmetric particle will increase step by step when the mass ratio of asymmetric particle to Polyaniline is 1? So far, nano-conductive asymmetric particles have been successfully prepared by hybrid method.
