Research Progress of Functional Aggregation-induced Emission Fluorescent Coatings

Abstract Functional coatings have become the mainstay of coating industry because of their excellent performanc es in waterproofing anti-fouling fire-resistant rust prevention and electromagnetic shielding etc.As one of a vital member of functional coatings unique functionality and artistic nature lies in fluorescent functional coatings guaran tee the promising application prospects in biomedicine chemical detection food engineering and special equip ments.Howeverby virtue of the notorious aggregation-caused quenching (ACQ) effect among traditional fluoro phores the utilizations of fluorescent functional coatings are severely limited.With the evolution of modern technolo gy the synthesis and development of aggregation-induced emission (AIE) materials effectively break this deadlock.Different from traditional fluorophores AIE materials emit strong fluorescence in aggregate state while almost quench ing when dissolved in soluble solvents.Owing to excellent fluorescent quantum yield high sensitivity photostability and outstanding resolution ratio AIE materials are considered as pigments alternatives in coating preparation.Mean while molecular structural variability induced controllable stimuli-responsive properties also provide new inspiration and feasibility for the preparation of multifunctional fluorescent films.Based on the particular emission properties of
