Using carbon dioxide and its sulfur analogues as monomers in polymer synthesis
The alternating copolymerization of one-carbon (C1) building blocks including carbon dioxide (CO2) and its sulfur analogues of carbon disulfide (CS2) and carbonyl sulfide (COS) with epoxides afford new copolymers, namely polycarbonates and polythiocarbonates, with tailored chain structures and properties. This review mainly focuses on the recent advances in C1-involved copolymeriz...

Enhanced Crystallization of Bisphenol-A Polycarbonate in Thin and Ultrathin Films by Supercritical Carbon Dioxide
The crystallization behavior of thin bisphenol A polycarbonate (PC) films after treatment in supercritical CO2 (ScCO2) was investigated by using polarized optical microscopy (POM) and atomic force microscopy (AFM). Experimental results indicated that the crystallization ability in thin PC film of 259 nm thick was higher than that in the bulk in a much wider temperature range, and the crystallizati...

Free volume and crystallinity of poly(ethylene naphthalate) treated in pressurized carbon dioxide
The free volume and crystallization behaviour of poly(ethylene naphthalate) (PEN) treated in pressurized carbon dioxide was studied, using Positron Annihilation Lifetime Spectroscopy (PALS) and Differential Scanning Calorimetry (DSC). PALS probes the values of free volume cavity sizes in materials, thus making it possible to investigate the effect of pressurized carbon dioxide treatment on free vo...

Cosolvent effect of water in supercritical carbon dioxide facilitating induced crystallization of polycarbonate
Water-induced crystallization of polycarbonate (PC) was investigated in water-saturated supercritical CO2 (scCO2) in the range of 80–1608C and 12–20 MPa, with the help of differential scanning calorimetry and wide angle X-ray diffraction. Compared with pure scCO2, the enhanced plasticizing effect of water-saturated scCO2 reduced the energy-barrier for the motion of polymer chains, henc...

High-throughput solubility measurements of polymer libraries in supercritical carbon dioxide.
A new method was developed which allows rapid parallel soly. measurements for libraries of materials in supercrit. fluids (SCFs). The technique was used to evaluate the soly. of a mixed library of 100 synthetic polymers including polyesters, polycarbonates, and vinyl polymers.

Supercritical Carbon-Dioxide-Assisted Deposition of Pt Nanoparticles on Graphene Sheets and Their Application as an Electrocatalyst for Direct Methanol Fuel Cells
关键字：graphene ， supercritical carbon dioxide ，Electrocatalyst
A combination of graphene with metal particles is particularly attractive due to the enhanced performance of the hybrid materials. However, direct loading of uniform metal
nanoparticles such as Pt on graphene remains a challenge due to the hydrophobic nature of graphene. We herein demonstrate that Pt nanoparticles with uniform size and high dispersion were deposited on graphene surfaces via a faci...

Methanol electrocatalytic oxidation on highly dispersed platinum–ruthenium/graphene catalysts prepared in supercritical carbon dioxide–methanol solution
关键字：graphene， supercritical carbon dioxide，PtRu
An effective, simple, low temperature and environmentally benign supercritical fluid (SCF) route is presented for preparing graphene-supported metal nanoparticles. With the assistance of supercritical carbon dioxide (SC CO2), ultrafine PtRu nanoparticles with an average size of 2.87 nm were very uniformly distributed on the surfaces of functionalized graphene sheets (FGSs) by the reduction of a mi...
