An organic/inorganic hybrid membrane composed of one-dimensional mesoporous silica rodlike materials inside the channels of polycarbonate filtration membrane (PC) was synthesized by using PC as the hard template and characterized by SEM, EDS and TEM. The experimental results demonstrate that the length and diameter of the one-dimensional silica rods formed inside the channels of PC are 9 μm and 200 nm, respectively. Moreover, it is found that as-synthesized silica rods in PC are mixed with the disordered warmlike and the ordered cubic mesophase structure, and the diameter of mesopores with cubic mesophase is estimated to be 8.5 nm. In addition, the adsorption behavior of myoglobin into such a membrane was investigated, and the adsorption amount was evaluated to be 5.85 mg/g.
