摘　　要：近年来,胶质气体泡沫因其多样的应用前景而受到研究人员的广泛关注。采用聚醚两性离子表面活性剂和黄原胶聚合物制备了胶质气体泡沫(CGA)流体,结合光学显微照相技术,对比分析不同制备条件下CGA流体的气泡尺寸及其分布情况,从而优化制备条件。结果表明:采用常规机械搅拌无法获得尺寸小于100μm的CGA流体。采用Waring-Blender法,基液体积为300 mL,搅拌速率为3 000 r/min,搅拌时间为3 min是较优的制备条件。在此条件下制备的CGA流体,气泡细小均匀,平均尺寸为62μm,尺寸分布最窄,稳定性较优。Recently,colloidal gas aphron(CGA)fluids have been much attended by researchers for their possible applications in various fields.In this study,polyether zwitterionic surfactant and xanthan gum polymer were utilized to generate CGA fluids.The average bubble size and size distribution of CGAs prepared under different conditions were compared and analyzed by using optical photographic technique,so as to determine an optimum preparation condition.Results showed that CGA fluids with bubble size less than 100μm could not be obtained by conventional mechanical agitation.The base fluid volume of 300 mL,stirring rate of 3000 r/min and stirring time of 3 min were found to be optimum conditions for the preparation of CGA fluids by the Waring-Blender method.In this condition,CGA fluid with acceptable stability and fine and uniform bubbles was obtained.It showed a narrow size distribution with an average bubble size of 62μm.
