| titleOfInvention | A kind of preparation method of nano-cellulose/chitosan composite foam |
| abstract | A kind of preparation method of nano-cellulose/chitosan composite foam, the present invention relates to cellulose composite material field, and it is low in order to solve the problems, such as the Biocompatibilities such as conventional foam, aeroge difference and Chitosan Composites heat endurance.The preparation method of composite foam：First, the biomass material containing cellulose is chemically treated and machinery solution fibre is handled, prepare nano-cellulose aqueous suspension；2nd, add chitosan to glacial acetic acid solution and prepare chitosan mixed solution；3rd, nano-cellulose aqueous suspension is mixed with chitosan mixed solution, obtains nano-cellulose/chitosan composite solution；4th, cryogenic freezing processing is carried out to composite solution；5th, processing is dried to the mixed solution freezed, obtains nano-cellulose/chitosan composite foam.The raw materials used present invention is natural macromolecular material, and good biocompatibility, hot cubical contraction is low, good thermal stability. |
