“…Normally, light‐diffusing particles (LDPs) are applied in the fabrication of light‐diffusing films. Typical organic–inorganic LDPs with rough surface structure contribute to superior light‐diffusing properties, as we have studied previously . However, the compatibility between inorganic nanoparticles and polymer resins is a vital problem that urgently needs to be addressed.…”

A facile “surface tension controlling” method is proposed for the preparation of nonspherical fluorinated acrylate polymer particles (FANPPs) with four different morphologies by adjusting the compositions of polystyrene (PS) cores and monomers in shell layers. The FANPPs are fabricated through an inexpensive and template‐free emulsion polymerization process that allows control of their morphologies. Scanning electronic microscopy, the Wilhelmy plate method, and differential scanning calorimetry are applied to investigate the structures and properties of the FANPPs. The formation mechanism of these unique morphologies is rationalized in terms of a selective wetting process, whereby surface tension and incompatibility between the PS cores and fluorinated shell layers are modified. These novel nanoparticles are first applied to fabricate light‐diffusing films that show both high transmittance and high haze value. The light‐diffusing properties are tested by means of a haze meter. The nonspherical structure of the FANPPs greatly influences their light‐diffusing properties.

“…A diffusion film is a thin film that can scatter light and is mainly applied in optical devices, displays, lighting, and solar cells. − The research on diffusion films is primarily aimed at the demand and improvement of optical materials and devices. In many optical applications, such as displays and lighting devices, people often hope to achieve uniform light intensity distribution and reduce reflection to improve observation and light utilization. − However, traditional transparent materials often cause light to reflect on the material surface, resulting in uneven light intensity distribution and wasted light energy . Therefore, researchers have started to explore how to achieve light diffusion effects by changing materials’ surface morphology to improve the performance of optical devices.…”

The increasing demand for improving the performance of optical devices and the development of nanotechnology have driven research on diffusion films. The preparation of diffusion films with welldefined microstructures can achieve uniform diffusion and scattering of light, thereby improving the efficiency and performance of optical devices. In this study, diffusion films with high transmittance and haze were prepared using PMMA@TiO 2 @SiO 2 (P@T@S) composite microspheres, and the PMMA microspheres and nanoparticles were combined through electrostatic attraction. As compared with PMMA microspheres, the P@T@S composite microspheres displayed better heat resistance as well as swelling resistance. Optical performance data showed that the P@T@S diffusion film had the perfect optical performance with a transmittance up to 90.5% and a haze of 88.3%. The excellent light diffusion effect of the P@T@S diffusion film was experimentally demonstrated, with the light through the film not only displaying the largest area but also maintaining a relatively high brightness. Our findings can provide reference and guidance for further development of light diffusion films, which are of potential application in optoelectronic devices.

“…7,8 Commonly used light diffusers can be roughly divided into inorganic particles and organic particles. Inorganic particles, such as titanium dioxide (TiO 2 ) and silicon dioxide (SiO 2 ), [9][10][11][12][13] are often opaque, resulting in the loss of light energy and the decrease of light transmittance, thus limiting the specific amount of addition. Organic particles, such as crosslinked polymethyl methacrylate microspheres (PMMA), silicone microspheres (SMS) and polystyrene microspheres (PS), generally have high transmittance, which enables part of the incident light directly pass through.…”

In this study, we presented a one‐step melt‐blending method to fabricate polypropylene (PP)/polycarbonate (PC) light‐diffusing materials. A promising balance between haze and transmittance was obtained by the addition of small amount of PC to the matrix. On the basis of Mie scattering theory and morphology analysis, the correlation between processing conditions and light‐diffusing properties was built. Low rotor speed and high viscosity ratio were beneficial to optical properties of PP/PC composites. To extend the advanced application, two general anti‐ultraviolet additives nanoscale titanium dioxide (Nano‐TiO2) and 2‐(2‐hydroxy‐5‐methylphenyl) benzotriazole (UV‐P) were added to impart UV‐shielding property to the composites. Their specific influences on the morphology and comprehensive properties of PP/PC composites were studied. It was found that the introduction of Rayleigh scattering raised by Nano‐TiO2 could strengthen the scattering effect and cause a significant reduction in light transmittance, while UV‐P had little effect on the optical properties of the light‐diffusing composites. In summary, this study prepared the PP/PC composites with high‐performance light scattering and UV‐shielding properties applying a facile blending method, which showed a potential application in flexible lightings and LCD displays.
