摘要

采用苯乙烯(St)、二乙烯基苯(DVB)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)为单体

在乙醇和水混合介质中通过无皂乳液聚合法制备了非球形聚苯乙烯(PS)粒子.通过FT-IR、TEM和激光粒度及电位分析仪对粒子的结构、形貌、粒径以及Zeta电位进行了表征.结果表明

所合成PS粒子均含三种单体结构单元

且形貌上均为非球形;随着DVB用量的增加

PS粒子形貌更趋于球形

粒径和单分散系数均逐渐增加;随DMC用量增加

PS粒子粒径随之增加

单分散系数逐渐减小

表面Zeta电位也逐渐增加;KHCO3用量的增加能使PS粒子粒径和单分散系数均增加;随着醇水比的减小

PS粒子粒径逐渐减小

而单分散系数则逐渐增加。

Abstract

The non-spherical polystyrene (PS) particles were synthesized via soap-free emulsion polymerization with styrene (St)

divinyl benzene (DVB)

methacryloyloxy trimethyl ammonium chloride (DMC) as monomers in ethanol and water mixed medium. The structure

morphology

particle size and surface potential were analyzed by FT-IR

TEM

laser particle size and potential analyzer. The results indicate that the PS particles contain three kinds of structural unit and have non-spherical morphology; With the increase of dosage of DVB

PS particle morphology tend to be more spherical

particle size and monodisperse coefficient increase gradually; With the increase of DMC dosage

PS particle size increase

monodisperse coefficient decreases

surface Zeta potential also gradually increased; An increase in the amount of KHCO3 can make the PS particles size and monodisperse coefficients increase; With the decrease of the alcohol water ratio

PS particle size decreases

while monodisperse coefficient increases gradually.
