May 13, 2025 · This simple yet effective model successfully predicts contact angle variations for surfaces with simple roughness patterns and strong wetting characteristics (where 0° < θ < 90°).

Oct 22, 2024 · Abstract Contact angle is an important measure of wetting in systems involving liquid–solid interfaces. This study focuses on estimating advancing and receding contact …

Jul 30, 2025 · In this work, measurements of advancing and receding contact angles (ACA and RCA) of water on PTFE surfaces were conducted at various temperatures and pressures, up …

Here, a comprehensive review of historical efforts in measuring the contact angles of water over a wide temperature range on a variety of solids, not limited to metallic surfaces, is presented.

On the contrary, hydrophilic materials are designed to attract water, leading to lower contact angles and more substantial wetting behavior. These materials often have polar or ionic …

Influence of surface roughness on contact angle and wettability This theory note explains how the surface roughness influences on the contact angle and wettability of the substrate.

Jan 1, 2024 · Before and after gelatinization at different temperatures (25, 37, and 60°C), contact angles for water (and formamide) and diiodomethane on starch-covered glass plates were …

Mar 30, 2022 · The relationship between the surface tension and the contact angle as well as equations that quantify this relationship are discussed.
