Abstract:

Stable waterborne polyurethane/silica hybrid dispersions were obtained by sol–gel reaction of tetraethoxysilane added to previously synthesized waterborne polyurethane nanodispersions. Two series of polyurethane/silica nanostructures with different silica contents were synthesized using pure polyurethane particles and polyurethane particles previously functionalized with (3-aminopropyl)triethoxysilane (APTES) as colloidal templates. The optimum experimental conditions for tetraethoxysilane sol–gel reaction (T = 75 °C and semi batch polymerization conditions) leading to the form

Abstract:

The reinforced clear coat on glass substrate was prepared by coating waterborne-polyurethane hybridized by silica sol or aluminate modified silica sol. To enhance the physicochemical property of the film, aluminate modified silica particle was prepared by the interaction between sodium aluminate and cation-exchanged silica. The hybrid thin films were developed in the range of the modified silica content varying from 0 to 20 wt%. The film, containing the modified silica content of 16 wt%, exhibits markedly improved properties as compared to the neat polyurethane and the polyurethane containing

Abstract:

Wear resistance is the key factor that affects the long-term use of leather. Graphene has excellent wear resistance properties, but ensuring the effective dispersion of graphene in resin is crucial for determining the performance of the material. In this work, silica modified with polydopamine (SiO2@PDA) was used as an exfoliation agent. Using the microfluidization process and water as the medium, silica-graphene hybrid nanoparticles (SiO2@PDA-G) were prepared from expanded graphite. These nanoparticles were further compounded with waterborne polyurethane (WPU), and a superfine fiber-based fab

Abstract:

Abstract The inadvertent transfer of thermal energy in industrial settings leads to a variety of issues such as heat loss from processing equipment and piping, increased energy usage, worker safety issues from contact with hot or cold surfaces, and associated costs. The traditional insulation methods to combat these issues include use of materials such as fiberglass and polyurethane foam, however thick layers of insulation can often hide severe maintenance problems such as corrosion under insulation (CUI). CUI occurs when moisture and condensation come into contact with steel surfaces undernea
