| titleOfInvention | Polydopamine-cellulose nanofibril photothermal conversion composite membrane |
| abstract | Aiming at the problem of low photo-thermal conversion efficiency of PDA materials in the prior art, the invention provides a polydopamine-cellulose nanofibril photo-thermal conversion composite film. The composite membrane is prepared by the following method: (1) the method comprises the steps of coupling mechanical treatment after acid treatment of a natural cellulose raw material to obtain cellulose nanofibrils with esterified surfaces, and preparing a wet film consisting of the cellulose nanofibrils, namely a CNF (carbon nano fiber) basement membrane, from cellulose nanofibrils dispersion liquid. The cellulose nanofibrils have a degree of substitution of ester groups of 0.2 to 1.5. (2) Drying the CNF basement membrane, and then soaking the CNF basement membrane into a dopamine aqueous solution to react for 1-48 h; taking out, and putting into an ammonia water/ethanol/water system or a tris (hydroxymethyl) aminomethane system for self-polymerization reaction for 20-50 h; taking out, and performing secondary drying treatment to obtain the polydopamine-cellulose nanofibril composite membrane. The composite film realizes ordered arrangement of PDA particles, greatly improves the photo-thermal conversion efficiency, and has wide application prospect. |
