主　　题：sepiolite microfiber high aspect ratio inorganic membrane flexibility 

摘      要：It is difficult to access exfoliated sepiolite(Sep)fibers with high aspect ratio from Sep *** traditional method used to purify Sep ore also reduces its aspect *** this study,impurities in the Sep ore were removed by acid activation followed by a cetyltrimethylammonium chloride(C16)treatment to organically modify the purified Sep by cation ***,the organically-modified Sep(O-Sep)was stripped and processed by an ultrasonic cell crusher to obtain Sep microfibers at a specific frequency for a given *** Sep samples had relatively high aspect ratio,compared with the Sep fibers gotten by traditional *** electron microscopy(SEM)and transmission electron microscopy(TEM)demonstrate the micro-morphology of exfoliated Sep samples in an intuitive ***,pure inorganic membrane prepared only with the exfoliated Sep fibers exhibited excellent flexibility,further demonstrating the excellent properties of Sep fibers with high aspect ratio.
