摘要： 用辛基三甲氧基硅烷对SiO2纳米球(SN)表面进行功能化修饰,制得了具有界面活性的SiO2材料(SN-C8-n,n=0.3,0.6,0.9和1.2),并将其作为起泡剂稳定气泡。研究了硅烷偶联剂的嫁接量、SN-C8-0.6的用量、NaCl的质量浓度及温度对气泡的影响。结果表明,当硅烷嫁接量为0.6 mmol/g,且将0.2 g SN-C8-0.6加入到2 mL质量浓度为0.05 g/mL 的NaCl水溶液中时,起泡性能最好且在25 ℃气泡可稳定72 h以上。

关键词: 二氧化硅, 界面活性, 气泡, 稳定性

Abstract: Interfacially active SiO2 material (SN-C8-n,n=0.3,0.6,0.9 and 1.2) was prepared by functional modification of SiO2 nano-particles (SN) with n-octyltrimethoxysilane,and then the material was used as a foaming agent to stabilize the foam.Effects of dosage of coupled silane,dosage of SN-C8-0.6,mass concentration of NaCl and temperature on the performance of the foam were investigated.Results showed that,when the dosage of silane coupled onto the SN is 0.6 mmol/g and 0.2 g SN-C8-0.6 is added into 2 mL of NaCl solution with mass concentration of 0.05 g/mL,best foam performance with stable time of 72 h under 25 ℃ can be resulted.

Key words: SiO2, interfacial activity, foam, stability
