Preparation of PVA Nanofiltration Membrane with Good Solvent Resistance Jiandong Zhang1, a, Li Wang2 1Department of science and technology, Ankang University, Ankang, China 2 Department of Politics and History, Ankang University, Ankang, China azjd111zjd@163.com Keywords: nanofitration membrane, PVA, composite membrane, PES Abstract.
However, most of the nanofiltration membranes are only used in the water treatment because the membrane materials are not stable in organic solvent, and the separation of organic solvent is very important in chemical industry [2].
In this work, PES ultrafiltration membrane is used as the support layer of the composite membrane and PVA is used as the functional material of the composite layer.

With the developments of micro-electric material, the lighting efficiency of LED can be 50- 200 lumen/watt and the color of LED light is pure and has thin frequency width [1].
Considering the process latency and rejection rate, the raw materials are set to 1000.
That means every 0.48 minute, a raw material should be created.

Understanding the behavior of the magnetic materials at nanoscale is, therefore, essential and important.
Spintronic device applications require a material with wide band gap semiconductors thus FeTiO3 is a suitable candidate for such applications.

For example, thermostat materials, many electronic contacts and aluminum aircraft panels are manufactured using roll bonding technology [1,2].
Numerous investigations have been carried out during the last years to identify the parameters which may affect the bond strength of roll bonded materials (e.g. see [3]).
For the sake of simplicity, it is assumed that two similar materials are supposed to be rolled.
