Research Progress on Preparation of Fluorescent Waterborne Polyurethane and Prospects for Its Application in Leather Industry
Fluorescent molecules have a wide range of applications in developers,luminescent materials,probes,biological imaging,sensors,and other fields.However,aggregation induced fluorescence quenching effects are prone to occur.In addition,small molecule fluorescent substances also have problems such as insufficient environmental protection,low safety,and poor processability.Therefore,some scholars combine small molecule fluorescent sub-stances with waterborne polyurethane to obtain fluorescent polymers with special luminescent properties,which have broad development prospects.This paper reviewed the research on physical blending and chemical modification of flu-orescent waterborne polyurethane,in order to further expand the application space of fluorescent waterborne polyure-thane in leather industry.
