Adhesive spacer particles were fabricated to ensure the uniform cell gap between the plastic substrates for application in flexible liquid crystal display ( LCD). Surface modification of rigid silica particles was performed to render adhesive polymer layer on the surface of the silica particles while maintaining the rigid properties. Methyl methacrylate ( MMA) and styrene were graft- polymerized onto silica surface by UV irradiation and characterization experiments confirmed the formation of covalent bond between polymer and silica particle. FE- SEM image analysis indicated substantial increase in mean diameter of the particles after UV- induced grafting of the monomers. T- peel test value of 2.7N/cm for PMMA film/Polyimide- PES substrate system also confirmed the applicability of these composites in flexible LCD.
