| titleOfInvention | A kind of preparation method of polypropylene carbonate/Cellulose nanocrystal composite material |
| abstract | The invention discloses a kind of polypropylene carbonate/Cellulose nanocrystal composite material preparation methods; the following steps are included: (1) under the protection of protective gas, Cellulose nanocrystal, propylene oxide, catalyst, co-catalyst and solvent is uniformly mixed and obtain propylene oxide/Cellulose nanocrystal dispersion liquid；(2) it is passed through carbon dioxide into the dispersion liquid, is then carried out home position polymerization reaction 5~25 hours at 20~120 DEG C in a sealed meter environment, obtains the Cellulose nanocrystal mixture of polypropylene carbonate cladding；(3) methanol extraction is diluted and used with solvent, is then dried to get polypropylene carbonate/Cellulose nanocrystal composite material is arrived.The present invention is improved by the Parameter Conditions of overall flow technological design and each step to preparation method key, can effectively solve the problem that nanocrystalline easy to reunite in polypropylene carbonate matrix, the non-uniform problem of dispersion of filler fibre element. |
