[J. Mater. Chem. B] Indocyanine green-functionalized bottle brushes of poly(2-oxazoline) on cellulose nanocrystals for photothermal cancer therapy
Deriving from the most abundant and renewable material, cellulose nanocrystals (CNCs) have drawnincreasing attention in nanomedicine as well as other biomedical fields due to their excellentphysicochemical properties and unique rod-like geometry. In this work, we report an efficient procedureto create biocompatible poly(...

Green Nanocomposites Based on Functionalized Cellulose Nanocrystals: A Study on the Relationship between Interfacial Interaction and Property Enhancement
Functionalized cellulose nanocrystals (PHCNs) were synthesized by grafting poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) onto cellulose nanocrystals (CNCs). The resultant PHCNs with high loading levels were uniformly dispersed into a PHBV matrix to produce fully biodegradable nanocomposites, which showed superior mechanical performance and thermal stability. Compared with those of neat PHBV,...

One-pot green fabrication and antibacterial activity of thermally stable corn-like CNC/Ag nanocomposites
Corn-like cellulose nanocrystals/silver (CNC/Ag) nanocomposites were prepared by formic acid/hydrochloric acid hydrolysis of commercial microcrystalline cellulose (MCC), and redox reaction with silver ammonia aqueous solution (Ag(NH3)2(OH)) in one-pot green synthesis, in which the preparation and modification of CNCs were performed simultaneously and the resultant modified CNCs could be as reducin...

Cellulose nanocrystals as green fillers to improve crystallization and hydrophilic property of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
The green nanocomposites of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with various cellulose nanocrystals (CNCs) contents were prepared by solution casting method. The effects of CNCs on the crystallization behavior, spherulitic morphology, crystal structure and hydrophilic property of PHBV were studied by differential scanning calorimeter (DSC), polarized optical micro...

A Green Strategy to Enhance a Liquid-Liquid Heterogeneous Reaction with a Magnetic Recyclable Pickering Emulsion
This work described a general strategy to enhance a typical organic-aqueous heterogeneous green oxidation reaction by introducing surface tunable magnetic nanoparticles into liquids to form a controllable Pickering emulsion. We synthesized cross-linked polystyrene (PS)-covered Fe3O4 nanoparticles grafted with different N-alkyl imidazoles and systematically discussed the effect of surface propertie...

Effective Electron Transfer between Heteropoly Blue and Graphene Oxide: A Green Approach to Graphene Synthesis
A facile electrochemical approach for the synthesis of graphene is developed by highly effective electron transfer from electron-rich heteropoly blue to graphene oxide. Reduced graphene oxide immobilized on a glassy carbon electrode (GCE) shows more positive potential for hydrogen evolution owing to the presence of the polyoxometalate electrocatalyst.

(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...

(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...

Green Synthesis of Silk Fibroin-Silver Nanoparticle Composites with Effective Antibacterial and Biofilm-Disrupting Properties
Natural polymer Bombyx mori silk fibroin is used as a biotemplate to produce silver nanoparticles in situ under light (both incandescent light and sunlight) at room temperature. Silk fibroin provides multiple functions in the whole reaction system, serving as the reducing agent of silver, and the dispersing and stabilizing agent of the resulted silver nanoparticles. As the reaction needs not any o...

Green Bionanocomposites from High-Elasticity “Soft” Polyurethane and High-Crystallinity “Rigid” Chitin Nanocrystals with Controlled Surface Acetylation
Castor oil-based polyurethane bionanocomposites with improved mechanical properties were prepared by the introduction of crab chitin nanocrystals from partial surface acetylation. Through controlled acetylation, some of the hydrophilic hydroxyl groups on the nanocrystals were replaced by hydrophobic acetyl groups in order to enhance the compatibility between the chitin nanoparticl...
