01 10 2014Irrespective of its brittleness upon drying PAN membranes are known as a low fouling material due to their hydrophilicity [1] compared to polysulfone (PSF) polyethersulfone (PES) polyethylene and polypropylene However more hydrophilic membranes usually suffer from poor mechanical and chemical stability [2-4] Despite good hydrophilicity and thermal stability [5] PAN membranes

Surface Modification of Polypropylene Microporous

Membrane-based biomedical processes have increased considerably in recent years However the natural disadvantages of common membrane materials such as hydrophobic surface and poor biocompatibility cause many side effects in use and cumber further applications In this work to meet the requirements of biomedical applications a novel sugar-containing monomer (d-gluconamidoethyl

Silica

Polypropylene micro?ltration membranes (PPMM mean pore size 0 2 μm porosity 75%) from Membrana (Germany) were cut into rounds with a diameter of 25 mm The samples were washed by acetone overnight to remove impurities adsorbed on the membrane surfaces and then dried in a vacuum oven at 40 C to a constant weight The dried membranes were totally prewetted by ethanol
