void formation
Examples
- This is due to three reasons : ( 1 ) sio2 influenced the phase behavior of suspensions , shifted the bimodal to lower nonsolvltil concentrations , so that it changed the skin characteristics and pore structure . ( 2 ) there was a kind of interfaeial micro - void ( this is the spaces between the phase of polymer matrix and distributive sio2 particles or ca phase ) existing in the membrane . this enhanced interconnectivity of the membrane pores
原因在于： sio _ 2影响铸膜液的分相条件，继而影响膜的表皮成孔性和膜孔结构； sio _ 2在膜基质中的存在，使平板膜变为多相结构，相与相之间的界面空隙形成了界面微孔，增加了膜孔的连通性： sio _ 2表面有许多si - oh基团，增加了膜的亲水性。
