NOVELTY - Preparing graphene oxide composite aerogel with aligned channel and thermal response comprises (1) using polyethylene glycol to prepare the cross-linking agent poly(ethylene glycol) diacrylate (PEGDA), (2) adding ammonium persulfate solution, graphene oxide dispersion, tetramethylethylenediamine, and PEGDA to the polyurethane acrylate solution and reacting, taking out the material formed after the reaction for equilibrium swelling to obtain PEGDA/polyurethane/graphene oxide composite hydrogel, and (3) placing the composite hydrogel in a directional freezing device for freezing, and then taking out and placing in a freeze dryer for freeze drying to obtain the composite aerogel. USE - The method is useful for preparing graphene oxide composite aerogel with aligned channel and thermal response. ADVANTAGE - The composite aerogel: has faster absorption rate and larger absorption capacity; and at the same time, due to the thermal response shape memory effect, the absorbed liquid can be squeezed out remotely.
