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
