설명

일반 설명

Poly(4-vinylphenol) (PVP) is a polymeric cross-linker mainly used as a layer to improve adhesion by forming a non-toxic and low cost film. It is an acidic polymer which consists of more than 100 hydroxyl groups in one molecule of PVP which result in high stability and complexation of the films.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Click here for more information.

애플리케이션

Cross-linked PVP can be used as a dielectric material to fabricate a low voltage single walled carbon nanotube (SWCNT) based thin film transistors. Organic semiconducting thin film transistor utilizes PVP as a barrier layer with photo-resistive properties which can be coated with a variety of charge carrying nanoparticles like silver nanoparticles (AgNPs), titanium oxide(TiO₂) and graphene oxide(GO).

Substitute for Novolac resins in photoresists, adhesion promoter and improves heat resistance in hot melt adhesives and surface treatment in metal finishing. Derivatives used as antioxidants and flame retardants in plastics. Component of polymer blends to modify surface characteristics and improve impact resistance.
