1. Water based polyurethane dries faster.In my opinion, this is the largest benefit of water based polyurethane. Usually, water based jobs can be done in 2 days and you can walk on it that night; oil based can take 3-5 days (pending on humidity) and you need to wait at least ...

Polyurethane-based nanoparticles as stabilizers for oil-in-water or water-in-oil Pickering emulsions Well-defined polyurethane (PU)-based grafted copolymers with poly(2-(dimethylamino) ethyl methacrylate) (PDEM) side chains were prepared by a combination o... C Ma,X Bi,T Ngai,... - 《Journ...
wood-based devices are cheap, biodegradable, abundant, and display high fluxes of evaporation compared with other nonbiodegradable photoabsorbers. Here we review the design and applications of wood-based solar steam generation devices, with focus on wood structure and properties, different types of dev...
Mung bean starch (MBS)-based edible films with incorporation of guar gum (GG) and sunflower seed oil (SSO) were developed in this study. MBS, GG, and SSO were used as the main filmogenic biopolymer, thickener, and hydrophobicity-imparting substance, respectively. To investigate the effect ...
The graphene/polyurethane (GN@PU) sponge was prepared via simple dip-coating PU sponges in graphene aqueous suspension containing cellulose nanowhiskers (CNWs), where CNWs played a vital role to facilitate the uniform graphene sheets coated on the skeletons of polyurethane sponge (PU). The super...
Plastic pollution is the biggest threat to marine ecosystem owing to its high rates of disposal and low recovery from the environment. Due to inefficiency
Magnetic, durable, and superhydrophobic polyurethane (PU) sponges were fabricated by chemical vapor deposition (CVD) of tetraethoxysilane (TEOS) to bind the Fe3O4 nanoparticles tightly on the sponge and then dip-coating in a fluoropolymer (FP) aqueous solution. The sponges were characterized using...
In this study, pomegranate peels (PPs) as an abundant fruit processing waste was used to produce cost-effective, eco-friendly, and high-quality activated carbon. The produced carbon (fossil free activated carbon) was used for immobilizing laccase to remo
