    Abstract: The present disclosure provides a fast and high-capacity intelligent cellulose-based oil-absorbing material and a preparation method and use thereof. The material includes an intelligent response layer and an adsorption layer. The intelligent response layer is a pH-responsive nanofiber layer with an adjustable pH response performance and is obtained by grafting hyperbranched polycarboxylic acid-modified polyethyleneimine on to carboxylated cellulose nanofibers. The hyperbranched polycarboxylic acid is prepared by melting and polycondensing at a high temperature, using trimethylolpropane as a core, citric acid as a reactive monomer, and p-toluenesulfonic acid as a catalyst. The adsorption layer is prepared by coating ferroferric oxide with the carboxylated cellulose nanofibers to prepare magnetic carboxylated cellulose nanofibers, and then modifying the magnetic carboxylated cellulose nanofibers with hexadecylamine.
