(ChemSusChem)Synthesis and Properties of a Bio-based Epoxy Resin with High Epoxy Value and Low Viscosity
A bio-based epoxy resin (denoted TEIA) with high epoxy value (1.16) and low viscosity (0.92 Pa s, 258C) was synthesized from itaconic acid and its chemical structure was confirmed by 1H NMR and 13C NMR spectroscopy. Its curing reaction with poly(propylene glycol) bis(2-aminopropyl ether) (D230) and methyl hexahydrophthalic anhydride (MHHPA) was investigated. For comparison, the commonly used dig...

(Green Chem.)Bio-based epoxy resin from itaconic acid and its thermosets cured with anhydride and comonomers
A novel itaconic acid (IA) based epoxy resin with curable double bonds (EIA) was synthesized by the esterification reaction between IA and epichlorohydrin (ECH). Its chemical structure was confirmed in detail by FT-IR, 1H-NMR and ESI-ION TRAP MS before being cured by methyl hexahydrophthalic anhydride (MHHPA). In order to manipulate the properties of the cured resin, divinyl benzene (DVB) and ac...

(Sci.China Chem.)Synthesis and properties of phosphorus-containing bio-based epoxy resin from itaconic acid
A phosphorus-containing bio-based epoxy resin (EADI) was synthesized from itaconic acid (IA) and 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO). As a matrix, its cured epoxy network with methyl hexahydrophthalic anhydride (MHHPA) as the curing agent showed comparable glass-transition temperature and mechanical properties to diglycidyl ether in a bisphenol A (DGEBA) system as well as g...

(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...

(Green Chem.)Polyesters derived from itaconic acid for the properties and bio-based content enhancement of soybean oil-based thermosets
A series of bio-based polyesters were synthesized by melt polycondensation of itaconic acid with diolsand glycerol without VOC emission. Their chemical structures were confirmed by FT-IR and 1H-NMR before they were made to copolymerize with acrylated epoxidized soybean oil (AESO). The thermal and mechanical properties of the resulting thermosets were investigated by differential scanni...

Synthesis and Properties of Bio-based Shape Memory Epoxy Resin from Rosin Acid
A bio-based shape memory epoxy resin was synthesized from rosin in order to achieve the sustainability of shape memory epoxy resin, and its chemical structure was determined by FTIR and 1H NMR. For comparison, a petroleum-based epoxy, diglycidyl ester of terephthalic acid (DGT) which has one benzene ring, was also synthesized. The properties including thermal and mechanical p...

(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...

(Macromolecules)Naturally Occurring Acids as Cross-Linkers To Yield VOC-Free, High-Performance, Fully Bio-Based, Degradable Thermosets
Naturally occurring carboxylic acids when used as cross-linkers with a highly functional bio-based epoxy resin result in thermosets having excellent physical and mechanical properties which are also degradable. Thermosets have many important applications (coatings, composites, adhesives, etc.), but they are typically made of nondegradable, nonrenewable materials. In this ...

【RSC Adv】Fabricating a morphology tunable patterned bio-inspired polydopamine film directly via microcontact printing
A robust and simple strategy of microcontact printing is provided to fabricate micro-patterned polydopamine (PDA) films with tunable morphology achieved by altering the concentration of PDA "ink" solution. Photoactive sites on the surface of patterned PDA films allow the further growth of polymer brushes by self-initiated photografting and photopolymerization (SIPGP) endowing the bio-inspired PDA ...
