Abstract
ABSTRACTInfrared laser‐ignited horizontal frontal polymerization is applied for the synthesis of unsaturated polyester resin (UPER) by copolymerizing unsaturated polyester with styrene (St), methyl methacrylate (MMA), and 2‐dimethylamino ethyl methacrylate (DMAEMA) monomers. Dependence of frontal velocity and temperature on the initiator and monomer concentration is discussed for St‐based UPER. These resins have also been characterized by Fourier transform infrared, thermogravimetric analysis, and scanning electron microscopy. The results reveal St‐based resins have superior crosslinked networks. Besides, the thermo‐pH responsiveness behaviors of DMAEMA‐based resins are demonstrated by swelling measurements under the conditions of different temperatures and pH values. Moreover, by introducing CdSe@ZnS quantum dots and CsPbBr3 perovskites into St‐ and MMA‐based resins, respectively, we realize the in situ generation of CdSe@ZnS‐UPER and CsPbBr3‐UPER composites with good fluorescence properties and fluorescent stability, which have potential application in optoelectronic devices such as light‐emitting diode and perovskite solar cells. © 2017 Wiley Periodicals, Inc.
