Modelling of Water Droplet Wettability on Anti-wetting Sheet of Sand/HDPE

High-density polyethene (HDPE) is widely used in personal protective equipment due to its distinctive mechanical and physical properties. In medical applications, its hydrophobic properties are precious for repelling body fluids and maintaining cleanliness. For instance, HDPE is used in coveralls, which require a durable material that protects against liquids and droplets. To further improve HDPE's performance, fillers can be added to enhance its mechanical and surface properties. One important characteristic to investigate is its wettability, which affects how fluids interact with the surface. In this study, computational simulations were conducted to assess the wettability of HDPE by measuring contact angles. These results were validated against published experimental data. The findings show that the contact angles from the simulations closely matched the experimental values, indicating that the computational method can successfully predict the wettability of HDPE and HDPE reinforced with sand fillers without extensive experimentation.
