| description | The invention provides bamboo nano-cellulose and polyurethane composite foam as well as a preparation method and application thereof. The preparation method comprises the steps: (1) preparing bamboo nanocellulose for adsorption by microwave liquefaction; (2) carrying out TEMPO oxidative grafting with carboxyl; and (3) preparing the bamboo nano-cellulose (CNC)/polyurethane foam adsorbing material.The material can be used for rapidly adsorbing heavy metal pollutants. A large amount of energy consumption and cost can be saved, TEMPO oxidative grafting is conducted on carboxyl with negative electricity, and the adsorption performance of the bamboo nano-cellulose on heavy metal ions can be remarkably improved; the bamboo nano-cellulose is dispersed by adopting dimethylformamide to obtain the nano-cellulose/polyurethane adsorption material with uniformly dispersed nano-cellulose, meanwhile, the foaming process flow can be greatly simplified by adopting a one-step foaming process, and the composite material with ide |
