Magnetic and Hydrophobic Composite Polyurethane Sponge for Oil–Water Separation

Investigation of the synergistic effect of titania micro and nanoparticles on the hydrophobic properties of polyurethane composite coating

One of the ways to improve the performance of ceramic insulators in polluted climates is to use polymer coatings reinforced with ceramic particles. The purpose of this study is to compare the effect of adding Titania nanoparticles and Titania micro-nanoparticles on hydrophobic properties of PU. In this method, stearic acid, which is a cheap and environmentally friendly material, was used for su...

Polyurethane Adhesives and Sealants Based on Hydrophobic Polyols

Thermosetting polyurethane polymers are staples of adhesive and sealant formulations used in a variety of industrial applications. Polyurethane materials generally provide reliable service under most application conditions, but the long-term performance and durability of some polyurethanes can be compromised by direct and prolonged contact with bulk water or high ambient humidity. The Dow Chemi...

Polyurethane Mixed Matrix Membranes for Gas Separation: A Systematic Study on Effect of SiO2/TiO2 Nanoparticles

In this study, the effect of SiO2 and TiO2 nanoparticles on the gas separation performance of the polyurethane (PU) membranes has investigated. Polyurethanes were synthesized by bulk two step polym...

HTPB-Polyurethane: A Versatile Fuel Binder for Composite Solid Propellant

Smart surfaces with switchable superoleophilicity and superoleophobicity in aqueous media: toward controllable oilwater separation

Advanced materials with surfaces that have controllable oil wettability when submerged in aqueous media have great potential for various underwater applications. Here we have developed smart surfaces on commonly used materials, including non-woven textiles and polyurethane sponges, which are able to switch between superoleophilicity and superoleophobicity in aqueous media. The smart surfaces ar...
