The ability to tune fluorescence in polymer composites via 2D materials, dyes, or interfacial modifications provides a versatile platform for advancing optoelectronics as the underlying mechanisms offer control over emission properties, leading to innovative materials. In this work, 2D-white pearl (2D-WP) has been synthesized from naturally occurring WP. Liquid crystal polymer (LCP) composites based on liquid crystal (LC) monomer mixture E7 have been produced via 3D printing. 2D-WP has been dispersed in the LCP composite to demonstrate LC-2D interaction and generation of fluorescence. It has been shown that by introducing interfaces, a secondary emission can be obtained from 2D-dispersed LCP composites. The interactions between the four monomers in E7 and 2D-WP have been simulated, depicting a reduction in the original bandgap of 4.31 eV for 2D-WP to 2.5 eV for LCP-2D composite. In this way, 3D-printed LCP in combination with 2D-WP is shown to be an exciting prospect in further optical and photonics studies. (AU) | |
