AI Technical Summary
The existing shape and structure of barium sulfate are not suitable as a light diffusing agent, and it cannot effectively scatter light. Furthermore, its purity and particle size distribution are uneven, which affects its optical performance.
Near-cubic barium sulfate was prepared by controlling reaction temperature, stirring speed, type and concentration of crystallizing agent, etc. Water-soluble polymer cellulose or silane coupling agent was used as crystallizing agent to control crystal growth and improve purity and particle size uniformity.
The prepared near-cubic barium sulfate exhibits excellent light diffusion properties, which improves the optical performance of the light diffusion film, simplifies the preparation process, and reduces production costs.
