Phenyl group-based fluorinated polymer dispersed liquid crystal composite films with high contrast ratio and low driving voltage
Polymer dispersed liquid crystal (PDLC) is a type of composite materials which is usually obtained by the phase separation during polymerization of liquid crystal/monomer mixtures, and it has shown potential applications in smart windows. In this work, the rigidity and flexibility of phenyl acrylate monomers were regulated by varying the number of benzene rings and their influences on the morphology and electro-optical properties of PDLC were discussed. The results showed that the PDLC films formed by monomers with one benzene ring possessed better performance. In addition, fluorination of monomers with a benzene ring could further enhance overall performance. The contrast ratio was significantly improved from 138 to 175, but the driving voltage is maintained at a lower value (6.9 V). This work provides a choice for optimizing electro-optical properties of PDLC films.
期刊介绍:
Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
