摘要
两亲纳米颗粒是一类重要的泡沫稳定剂,然而复杂的制备工艺限制了其推广应用。采用一锅法制备了一种含磺酸根亲水单元的两亲纳米颗粒:首先利用水解共缩合反应制备了含苯环和巯基的纳米颗粒,之后利用过氧化氢将巯基氧化成磺酸基,制备出以磺酸根作为亲水单元、苯环作为疏水单元的两亲纳米颗粒。在结构表征的基础上,研究了纳米颗粒的稳泡性能。结果表明:基于一锅法可以有效调控两亲纳米颗粒的接触角,颗粒的最优加量为0.2%;50℃、NaCl质量浓度为20 g·L^(-1)时,单一SDS泡沫半衰期为17.41 min,加入两亲纳米颗粒后泡沫半衰期提升至52 min。
Amphiphilic nanoparticles are an important foam stabilizer.However,its application is limited by the complex preparation method.In this study,sulfonate amphiphilic nanoparticle was synthesized by one-pot.Based on the co-hydrolysis and condensation reaction,the nanoparticle containing phenyl and thiol groups was prepared.Then,thiol group was reacted with H_(2)O_(2) to prepare the amphiphilic nanoparticle with phenyl and sulfonic groups.Based on the structural characterization,the influence of the nanoparticle on foam ability was researched.The results showed that the contact angle could be regulated by changing reaction time.The optimal dosage of the nanoparticle was 2 g·L^(-1).When NaCl mass concentration was 20 g·L^(-1)and the temperature was 50 C,the half-life of single SDS foam was 17.41 min,the half-life was increased to 52 min when amphiphilic nanoparticles were added.
