Due to its biodegradable nature, RBHM is ideal for disposable loose fill bags and packages. The possibilities of the formation of various types of ordered textures that ensure high contact angles on the surfaces of hydrophobic materials and prerequisites for thermodynamic stability of the heterogeneous wetting regime of such surfaces are analysed. Conference paper, For a space heating system, extra thermal energy storage generally has to be purchased and is a detriment to the economics of these systems. These ceramic materials adsorb water from the air or make direct contact with water; therefore, the property and lifetime of the ceramics are greatly influenced [103]. Commercial sand core funnels (SCs) are embedded with multilevel pore size and surface roughness, which are excellent models to study the mechanism of surface wettability. The study also shows that equilibrium changes in the morphology of an assembly are not good indicators of the responsive host-guest properties of a polymer assembly.
