Poly-Siloxane Modified Poly-Urethane based Long Life, High Gloss and Colour Retaining Coatings for Marine Applications

Poly-Siloxane Modified Poly-Urethane based Long Life, High Gloss and Colour Retaining Coatings for Marine Applications

A ship or a marine structure operates in extremely harsh corrosive environment. Marine environment is more aggressive than most inland environments. Several areas of sea going vessel, typically consist of, the superstructure, boot-top area under splash zone, fully immersed areas such as ship-hull. It is well known now that the rate of corrosion of is generally, the highest for splash zone where...

Poly(caprolactone-co-oxo-crown ether)-based poly(urethane)urea for soft tissue engineering applications.

Random copolymers of epsilon-caprolactone and 2-oxo-12-crown-4 ether, poly(CL-co-OC), were used as soft segments in the synthesis of a set of poly(urethane)urea thermoplastic elastomers. With increasing OC content, the soft segment crystallinity decreased, which influenced the mechanical properties: strain induced crystallization disappeared upon the introduction of OC into poly(CL). The materi...

Poly(oxyethylene) based surface coatings for poly(dimethylsiloxane) microchannels.

Control of surface properties in microfluidic systems is an indispensable prerequisite for successful bioanalytical applications. Poly(dimethylsiloxane) (PDMS) microfluidic devices are hampered from unwanted adsorption of biomolecules and lack of methods to control electroosmotic flow (EOF). In this paper, we propose different strategies to coat PDMS surfaces with poly(oxyethylene) (POE) molecu...

Spotlight- Modified poly(vinylpyrrolidone)

Cross-linked poly(vinylpyrrolidone) (PVP) is a heterogeneous and polymeric support that has been widely used in the preparation of numerous reagents and catalysts because of its commercial availability, stability, reasonable high loading capacity, good physicochemical structure and facile functionalization. Beside various applications in industry such as stabilizer, sugar coating and film coati...
