【19 Journal of Materials Chemistry A】 Striking influence of Fe2O3 on the "catalytic carbonization" of chlorinated poly(vinyl chloride) into carbon microspheres with high performance in the photo-degradation of Congo red
A one-pot approach was demonstrated to effectively synthesize carbon microspheres through “catalytic carbonization” of commercial chlorinated poly(vinyl chloride) (CPVC) microspheres by Fe2O3 at 700 °C. Without Fe2O3, a “sponge-like” carbon lump was obtained. However, after adding Fe2O3 (even 0.5 g per 100 g CPVC) into CPVC, carbon microspheres with octahedral Fe3O4 microcrystals uniformly em...

【15 Industrial & Engineering Chemistry Research】 Striking influence about HZSM-5 content and nickel catalyst on catalytic carbonization of polypropylene and polyethylene into carbon nanomaterials
A one-pot approach was established to effectively convert polypropylene (PP) and linear low density polyethylene (LLDPE) into carbon nanomaterials (CNMs) including cup-stacked carbon nanotubes and carbon nanofibers under the combined catalysis of HZSM-5/NiO or HZSM-5/Ni2O3 at 700 °C. The effects of HZSM-5 content, a nickel catalyst, and the carbon precursor on the morphology, microstructure, phas...

【14 The Journal of Physical Chemistry C】 Catalytic carbonization of chlorinated poly(vinyl chloride) microfibers into carbon microfibers with high performance in the photo-degradation of Congo red
A simple approach was reported to prepare carbon microfibers embedded with octahedral Fe3O4 crystals (Fe/CMFs) through catalytic carbonization of chlorinated poly(vinyl chloride) (CPVC) microfibers using Fe3O4 as catalyst at 700 °C. Without Fe3O4, irregular carbon was obtained. However, after adding a proper amount of Fe3O4, carbon microfibers with uniform size were prepared. The influence of Fe3...

【09 Industrial & Engineering Chemistry Research】 Synergistic effect between a novel char forming agent and ammonium polyphosphate on flame retardancy and thermal properties of polypropylene
The performances of a novel char forming agent containing spiro and caged bicyclic phosphate (SBCPO) and its mixture with ammonium polyphosphate (APP) were investigated. The flame retardancy of the polypropylene (PP)/SBCPO/APP system was evaluated by the limiting oxygen index (LOI), the UL-94 test, and the cone calorimeter test. The maximum LOI value of PP/intumescent flame retardant (IFR) could r...

[Journal of Industrial and Engineering Chemistry] Renewable Biomass Derived Hierarchically Porous Carbonaceous Sponges and Their Magnetic Nanocomposites for Removal of Organic Molecules from Water
This work describes the preparation, characterization and removal capability of a novel biomass derived carbonaceous sponges (CS) and their nanocomposites. The CS has hierarchically porous structure which is composed of lamellar structures and secondary porous structures. The pore size is on a scale from 1 nm to 200 mm. Utilizing the CS as adsorbents, rapid removal of model organic molecules, in...

ACS Sustainable Chemistry & Engineering——Co-depositing mussel-inspired nanohybrids onto 1D fibers under “green” conditions for significantly enhanced surfacial/interfacial properties
Co-deposition of mussel-inspired nanohybrid coating was realized onto carbon fiber (CF) surface via co-incubation in the dopamine (DA) and octaammonium polyhedral oligomeric silsesquioxane (POSS-NH2) mixed aqueous solution. The deposition procedure was conducted under ambient conditions, and no harsh conditions and toxic solvents were needed. The surface morphology, compositions, and energies of C...

【Composites Science and Technology】Facile synthesis of imidazole microcapsules via thiol-click chemistry and their application as thermally latent curing agent for epoxy resins
A novel method was developed to encapsulate 1-benzyl-2-methylimidazole (1B2MZ) to produce microcapsule-type latent curing agent using thiol-click reaction in an oil/water emulsion. The fabrication process was significantly simplified and required reaction time was greatly shortened due to the efficiency of click chemistry. In the oil phase, 1B2MZ was mixed with reactive monomers, 1,3,5-tri-2...

【ACS Sustainable Chemistry & Engineering】Effect of the Structure and Length of Flexible Chains on Dendrimers Grafted Fe3O4@SiO2/PAMAM Magnetic Nanocarriers for Lipase Immobilization
Polyamidoamine (PAMAM) dendrimers have been widely applied in biomacromolecule immobilization, catalysis carriers, gene therapy, and drug delivery. However, there is still a lack of systematic research about lipase and protein immobilized by PAMAM dendrimers. Herein, we used three types of amine reagents to graft dendritic macromolecules on Fe3O4 nanoparticles and obtained a variety of Fe3O4...

(Macromolecular Chemistry and Physics) Generation Mechanism of Oxidation Products during the Air Atmosphere Oxidation of SEBS/PP Blends: Tracked by Two-Dimensional Correlation Infrared Spectroscopy
In this paper, the generation mechanism of oxidation products during the oxidation of the SEBS/PP blend in air atmosphere was investigated using temperature-dependent FTIR combined with 2D correlation infrared spectroscopy. DSC, TG, and PCMW2D found three processes associated with SEBS/PP oxidative degradation. The 2D correlation analysis was used to study the sequential order of groups’ moveme...
