Light-diffusing composite material based on polystyrene and hollow glass microspheres

Abstract

Granulated compounds based on polystyrene with hollow glass microspheres in different proportions were made on a twin-screw extruder. Microspheres were added to polystyrene composition in order to get light-diffusing material with optimal proportion of light transmission and light diffusion properties. The microspheres showed stability due to increased strength in processes. Adding the microspheres led to an increase in the light diffusion factor and to a reduction in the light transmission factor and the material density. The filler gave light diffusion properties to polystyrene in the research doses, whereas the light transmission factor reduced to the acceptable value. The microspheres may be researched additionally for giving light diffusion properties to polymeric materials, used in light engineering.

Evaluation of crystallinity, thermal, mechanical and morphological features of high density polyethylene composites reinforced with crosslinked semifluorinated acrylate polymer microspheres

“…[19][20][21] Especially, the polymer-based microspheres make possible to fabricate rigid, endurable, functional, less susceptible to breakage and lightest filler particles for the composites. 22 Such microspheres with different morphological properties can be produced by means of the suspension, dispersion, emulsion, spray drying, solvent extraction, precipitation as well as inverse-suspension methods. 23,24 Additionally, using the microspheres as filler in thermoplastic and thermoset composites creates positive effect during both extrusion and injection molding processes due thanks to its ball-bearing behavior by creating sliding effect.…”

A sound-absorbing and heat-insulating collagen fiber composite material

“…Hollow glass microspheres improve the compressive strength of epoxy resins and make low-density deep-sea buoyancy materials, 32 Hollow glass microspheres filled into polystyrene material to impart light-diffusing properties. 33 In this work, polystyrene hollow microspheres are filled into animal skin materials, in order to improve the strength of the material and increase the function of noise reduction and heat insulation. The polymer microspheres with core-shell structures were prepared by continuous emulsion polymerization with carboxyl-containing polymer latex particles as the core and styrene as the shell monomer.…”
