15. Photosensitive poly(ether sulfone)s for thiol/ene UV curable coatings: synthesis, characterization and crosslinking
Novel photocrosslinkable poly(ether sulfone)s copolymers with allyl pendants (AS-PES) have been synthesized from 3,3''-diallyl-4,4''-dihydroxydiphenyl sulfone (DA-DHDPS), 4,4''-dihydroxydiphenyl sulfone (DHDPS) and 4,4''-dichlorophenylsulfone (DCDPS). The resulting polymers could be photocrosslinked in the presence of thiol at room temperature. The crosslinking process was monitored by "Real Time ...

Room-temperature nitrogen -dioxide sensors based on ZnO1?x coatings deposited by solution precursor plasma spray
The stoichiometric ZnO has a bandgap greater than 2.6 eV and has no or weak response to visible light, which greatly suppresses its applications. We report here that a process of solution precursor plasma spray (SPPS) can effectively narrow the bandgap and extend the absorption of ZnO to visible light region, which mainly results from highly concentrated oxygen vacancies generated during SPPS proc...

105. Oral delivery of insulin using CaCO3-based composite nanocarriers with hyaluronic acid coatings
Abstract: A facile and green reversed-phase microemulsion co-precipitation method has been developed for fabrication of CaCO3-based composite nanocarriers (NCs) with hyaluronic acid (HA) coatings for oral delivery of insulin. The cell viability of resultant CaCO3-based composite NCs against HT-29 cells was analyzed with different concentration. The chemical stability of loaded insulin against di...

(Prog. Org.Coat.)Synthesis of bio-based unsaturated polyester resins and their application in waterborne UV-curable coatings
In this paper, three bio-based unsaturated polyesters were synthesized from itaconic acid and different diols which could be derived from renewable resources. Their chemical structures were confirmed by FT-IR, 1H NMR and acid value as well as hydroxyl value. Waterborne UV curable networks based on these polyesters were manufactured and their mechanical properties, thermal stability and coating p...

(Prog. Org. Coat.)High Bio-based content waterborne UV-curable coatings with excellent adhesion and flexibility
A series of bio-based unsaturated polyesters was synthesized by melt polycondensation of itaconic acid with 1,4-butanediol and glycerol. Their chemical structures were confirmed by FT-IR, 1H NMR, acid and hydroxyl values. Waterborne UV curable dispersion coatings based on these polyesters and acrylated epoxidized soybean oil (AESO) were formulated. The average particle size and their stability b...

(J. Coat. Technol. Res.)Effects of solvents on the curing and properties of fully bio-based thermosets for coatings
With the increasing concern about the depletion of fossil reserves and greenhouse gas emissions, it is desired to replace coatings which are made using petrochemical-based materials with renewable alternatives such as bio-based polymers. In this paper, fully bio-based thermosets for coatings were prepared from epoxidized sucrose soyate (ESS) derived from sucrose an...

Multifunctional cotton fabrics with graphene/polyurethane coatings with far-infrared emission, electrical conductivity, and ultraviolet-blocking properties
In order to introduce multifunctional properties into flexible cotton fabric, graphene and waterborne anionic aliphatic polyurethane composites were prepared and then deposited on the surface of the fabric substrate through facile pad-dry-cure process. The fabrics thus obtained were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy, and their functional prop...

Double-layered reactive microcapsules with excellent thermal and non-polar solvents resistance for self-healing coatings
Double-layered polyurea microcapsules containing hexamethylene diisocyanate (HDI) with outstanding shell tightness have been successfully synthesized via interfacial polymerization reaction in an oil-in-water emulsion. The resultant capsules were systematically characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and Fourier...
