Control the structure of the polyacrylate/epoxy resin film through photopolymerisation

ABSTRACTDouble-layered polymer-stabilised cholesteric liquid crystal (PSCLC) films constructed from epoxy resin and polyacrylate were prepared based on photopolymerisation-induced phase separation. Moreover, a PSCLC film with an interpenetrating network was prepared through a one-step photopolymerisation approach. A colourful pattern was prepared based on these two approaches, which was suitably applied for decoration.Display full sizeKEYWORDS: Epoxy resinacrylateliquid crystalphotopolymerisationcolorful pattern Disclosure statementNo potential conflict of interest was reported by the authors.Supplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/02678292.2023.2290291.Additional informationFundingThis work was supported by the National Nature Science Foundation of China [52273212], the Key Laboratory of Polymeric Materials Design and Synthesis for Biomedical Function and the Project of Scientific and Technologic Infrastructure of Suzhou [SZS201905].
