Materials and methods Membrane The hollow fiber polyvinylidene fluoride (PVDF) membrane was obtained from a pilot membrane module device, which was supplied by Dow with an average pore diameter of 0.1 μm.
It can be observed from the section analysis that the AFM ‘‘valleys’’ have disappeared in the fouled membranes; this is due to the fill of membrane pore structure by foulant materials.

Effects of Hydrothermal Crystallization on the Morphologies and Photocatalytic Activity of TiO2 Nanotubes Suqin Liu1,a, Ying liang*1,b 1Department of Chemical engineering and Food Science; Hubei University of arts and science, Xiangyang 441053, P.
Moreover, it is a low temperature technique for materials development, widely applied in industrial processes for ceramic synthesis [14].
When the hydrothermal time is 1 h, the arrays were deformed to materials like gel which covered on the surface blocked the tubes, demonstrating the dissolution precipitation mechanism.

So it is based on many composite materials for biomedical applications.
Unlike conventional materials, composites can have many properties not commonly found in a single material [2].
