Fabrication of superhydrophilic antifouling and chemical resistant nanofiber using titanium dioxide

Organic fouling on membranes have been proven to be a major drawback of membrane technology. Since most membranes are made with polymers such as polypylene, polysuflone and polyvinylidene fluoride, they tend to be naturally hydrophobic. This hydrophobicity is the main reason which causes organ...

description Organic fouling on membranes have been proven to be a major drawback of membrane technology. Since most membranes are made with polymers such as polypylene, polysuflone and polyvinylidene fluoride, they tend to be naturally hydrophobic.
