Fabrication of Fe-doped Co-MOF with mesoporous structure for the optimization of supercapacitor performances
The synergy effect between different components has attracted widespread attentions because of improved activity, selectivity and stability than single component. In this paper, we fabricated mesoporous hybrid dual-metal Co and Fe containing metallic organic framework (Co/Fe-MOF), Fe-MOF, and Co-MOF in the ionic liquid (IL)/supercritical CO2 (SC)/surfactant emulsion system, an...

Electrochemically assisted ethylene (co-)polymerization with a vanadium-based Ziegler-Natta catalyst
A facile and efficient electrochemically assisted ethylene polymerization and ethylene-propylene copolymerization with the widely used VOCl3/ethylaluminum sesquichloride (EASC) catalyst system was demonstrated. The low-activity and/or inactive low-valence-state V species present in the catalyst were oxidized to high-valencestate V through electrochemical methodology. Thus, the catalytic activity...

Preparation and properties of RE3+ doped luminescent co-polymer by solution copolymerization
Bonded type RE3+ doped luminescent co-polymer was synthesized by solution free radical copolymerization. The influence of charge sequence, monomers and co-polymerized method on properties and structures of the co-polymers was studied. The emission intensity of the co-polymers at different RE3+concentrations was tested. The results showed that the co-polymers of Eu-PSt and Eu-PMMA both had wid...

Surface grafting of cellulose nanocrystals with poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
Chemically modified cellulose nanocrystals (CNCs) were synthesized by grafting poly(3-hydroxybutyrate-co-3-hydroxyvalerate)(PHBV) onto CNCs via homogeneous acylation reaction between N,N-dimethyl formamide(DMF) by using toluene diisocyanate (TDI) as coupling agent and dibutyltin dilaurate as catalyst. The resulting copolymers were studied by...

Effect of Cellulose nanocrystal on Crystallization Behavior of Poly(3–hydroxybutyrate–co–3–hydroxyvalerate)
The biodegradable nanocomposites of poly(3–hydroxybutyrate–co–3–hydroxyvalerate) (PHBV) with different cellulose nanocrystals (CNCs) contents were prepared by a solvent casting method. The effects of CNCs on the crystallization behavior of PHBV were studied by DSC. The DSC results showed that compared to PHBV, the melt crystallization temperature increased to 92.3 °C fo...

Effects of Microcrystalline Cellulose on the Thermal Properties of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
The composites of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with different microcrystalline cellulose (MCC) contents were prepared by a solvent casting method. The effects of MCC on the thermal properties of PHBV were studied by TGA and DSC. The DSC results showed that the melt crystallization temperature of the PHBV/MCC increased from 41.9 °C for PHBV to 59.8 °C ...
