| titleOfInvention | A kind of preparation method of antibacterial composite nanometer filtering film |
| abstract | The preparation method that the invention discloses a kind of antibacterial composite nanometer filtering film.Including: the aqueous phase solution of the attapulgite that (1) porous support membrane is modified with the compound containing two or more reactive amino and chitosan quaternary ammonium salt contacts；(2) porous support membrane after aqueous phase solution infiltrates removes unnecessary aqueous phase solution；(3) porous support membrane after step (2) process contacts with the organic phase solution of the chloride compounds containing two or more acid chloride group, obtains composite membrane；(4) dry, heat treatment, prepare the described composite nanometer filtering film containing inorganic particulate after washing.The present invention passes through interfacial polymerization by attapulgite loaded modified for chitosan quaternary ammonium salt to composite nanometer filtering film functional layer, composite membrane nanofiltration flux is made to obtain lifting by a relatively large margin, meanwhile, chitosan quaternary ammonium salt can make again the anti-microbial property of composite nanometer filtering film be improved. |
