Abstract
The present invention discloses a near-infrared regenerative intelligent fiber-based adsorptive material and a preparation method and use thereof. The material is obtained by chemically grafting a stepwise dual-temperature stimuli-responsive polyethyleneimine onto a carboxylated cellulose nanofiber matrix to prepare a stepwise dual-temperature stimuli-responsive intelligent nanofiber, and combining the stepwise dual-temperature stimuli-responsive intelligent nanofiber with a photosensitizer having near-infrared stimuli-response to prepare a stepwise dual-temperature/near-infrared stimuli-responsive intelligent nanofiber, and then by using a crosslinking agent to directly crosslink and combine the stepwise dual-temperature/near-infrared stimuli-responsive intelligent nanofiber with a hyperbranched polyamine in one step. The material has a stepwise dual-temperature/near-infrared stimuli-response, high density of amino group (greater than 14 mmol/g), and nano cavities.
