PVDF membrane surface modification and its application in water treatment(Chinese Edition)

Pub Date: 2014-10-01 Pages: 154 Language: Chinese Publisher: National Defense Industry Press PVDF membrane surface modification and its application in water treatment to PVDF membrane material basis. based on supramolecular chemistry. molecular binding Effect of chemical crosslinking between the PVDF membrane surface modification. is significantly reduced membrane water contact angle after modification. and the pure water flux significantly increased. and the performance of the modified membrane surface structures were characterized. the results showed that change After stable film surface hydrophilic group. showed strong hydrophilicity and structural stability. maintain a good microporous structure. The modified membrane used in low concentration wastewater. micro-polluted water. the treatment effect is good. A series of studies to PVDF membranes in water treatment applicat...
