Tuning of Smart Multifunctional Polymer Coatings Made by Zwitterionic Phosphorylcholines

Tailor-made zwitterionic polyurethane coatings: microstructure, mechanical property and their antimicrobial performance

Antimicrobial coating is of great important in leather finishing. Herein, we report a newly synthesized polyurethane with zwitterionic sulfobetaine side groups and evaluate their performance in the antifouling leather coatings. The microstructure of the synthesized zwitterionic polyurethane (iNPU) films has been examined by Fourier transform infrared (FTIR), X-ray diffraction (XRD) and atomic f...

Nanocomposite Based Multifunctional Coatings

Chitosan-Recombinamer Layer-by-Layer Coatings for Multifunctional Implants

The main clinical problems for dental implants are (1) formation of biofilm around the implant-a condition known as peri-implantitis and (2) inadequate bone formation around the implant-lack of osseointegration. Therefore, developing an implant to overcome these problems is of significant interest to the dental community. Chitosan has been reported to have good biocompatibility and anti-bacteri...

A zwitterionic triphosphenium compound as a tunable multifunctional donor.

The preparation of a novel triphosphenium zwitterion featuring di-, tri-, and tetra-coordinate phosphorus centres derived from a 1,2,4-tris-(diphenylphoshinyl)cyclopentadienyl framework is described. The reactivity of this potentially multidentate donor with protons, elemental sulfur and gold(i) chloride is examined, and the preferential reactivity of the pendant phosphine group over the P(i) c...

Corrosion Sensing Smart Polymeric Coatings

Smart materials cover a wide and developing range in engineering & medical application. This paper presents the “Stimuli-sensitive/smart” polymeric systems which can overcome dramatic property changes responding to small changes in its surrounding environment. Here there is a corrosion resistant or protective smart polymeric coating and paints have been described. Additional smart-coating princ...
