酯基三甲氧基有机硅季铵盐的性能研究
Study on the properties of ester trimethoxy organosilicon quaternary ammonium salt
摘要
Abstract
The surface properties and biodegradation characteristics of the ester trimethoxy organosilicon quaternary ammonium salt (ETOQAS)were measured. The results showed that at 25 ℃,the critical micelle concentration (cmc)of ETOQAS measured by surface tension method is 0. 01 g / L,and γcmc is 15. 72 mN/ m. Meanwhile,NaCl was added into ETOQAS aqueous solution,and its cmc,measured by steady - state fluores-cence method shows decreasing. As the mass concentration of ETOQAS increases,the contact angle on surface of iron and paraffin wax decreases. ETOQAS can be completely biodegraded within 3 d.关键词
