Abstract
This research is based on the development and evaluation of high-density polyethylene (HDPE) film reinforced with titanium dioxide (TiO₂), having the potential to reflect near-infrared (NIR) radiation. for its use in agrotextile shade-nets developments. The aim is to reduce the temperature inside the agrotextile shade net by reducing heat buildup without compromising visible light transmission. Twin-screw extrusion process was used for the development of HDPE composite film by incorporating different concentrations of TiO₂ (0.1–0.7 wt%) pigment. The developed film was characterized to assess TiO₂ particle dispersion, IR reflectance, and light diffusion properties. The results showed that HDPE film containing 0.5 wt% TiO₂ particles had an IR reflectance of 20.87% and 84% visible light transmission. These results indicate the potential of TiO₂-infusion in HDPE polymer matrix as a practical and energy-efficient solution for thermal control in Agrotextile shade-net applications.
