Fixation of carbon dioxide concurrently or in tandem with free radical polymerization for highly transparent polyacrylates with specific UV absorption
It is still a challenging issue to combine the coupling reaction and free radical polymerization (FRP) for well-controlled and efficient synthesis of polyacrylates bearing the cyclic carbonate group from carbon dioxide (CO2) and vinyl epoxides. This work describes the efficient catalytic synthesis of poly(2-oxo-1,3-dioxolane-4-yl)methyl methacrylate (PDOMA) from CO2 and glycidyl methac...

Functionalization of cotton fabric with graphene oxide nanosheet and polyaniline for conductive and UV blocking properties
Multifunctional cotton fabric with high electrical conductivity and ultrastrong UV radiation protection properties was successfully fabricated by coating graphene oxide (GO) nanosheet dispersion on fabric surface via vacuum filtration deposition (VFD) method, and then the treated fabric was assembled with polyaniline (PANI) by in-situ chemical polymerization process. The structure and morphologica...

Enhanced thermal, UV blocking and dye absorptive properties of chitosan/poly (vinyl alcohol)/graphene oxide fibers
Ductile appearance, remarkable length-diameter ratio, flexible fabrication properties and featured additional functions of functional composite fibers elicit great interest in applications. In this paper, chitosan/poly(vinyl alcohol) composite fibers with different graphene oxide additive (1-7 wt.%) were spun via continuous wet-spinning route and the resultant fibers revealed improved thermal, UV ...

Polymer Chemistry 2015: Real Time Quantification of the Chemical Cross-Link Density of a Hydrogel by in situ UV-vis Spectroscopy
In this paper, we prepare a hydrogel in a green way via the redox reaction between phenol groups and EosinY by visible light irradiation. Eosin Y shows significant absorption at 515 nm while the reduced product does not. A series of control experiments show that almost 100% of the consumed Eosin Y is reacted with phenol groups to form cross-link points. On the basis of the two results, the chemica...

[2014][J. Mater. Chem. C, 2014,2: 2431-2438]Panchromatic Small Molecules for UV-Vis-NIR Photodetectors with High Detectivity
Two donor–acceptor–donor (D–A–D) type low-bandgap small molecules, M1 and M2, with bis(2-thienyl)-N-alkylpyrrole (TPT) as the donor and thieno[3,4-b]thiadiazole (TT) as the acceptor were designed and synthesized. The absorption, transmission, electrochemical, thermal and film properties were studied. The compounds showed panchromatic absorption in the spectral range of 300–1000 nm. Moreover...

J. Membr. Sci, 2015, published online: Isoporous membranes with gradient porosity by selective swelling of UV-crosslinked block copolymers
Selective swelling of amphiphilic block copolymers (BCPs) is an effective and nondestructive pore-making strategy. Here we coupled swelling-induced pore generation with UV crosslinking to fabricate BCP isoporous membranes with gradient porosity. Polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) solutions were coated onto macroporous supportin...

UV cross-linked redox-responsive hydrogels for co-delivery of hydrophilic and hydrophobic drugs.
A novel redox-responsive hydrogel was designed for the co-encapsulation and controlled release of hydrophilic
and hydrophobic drugs, using 5-fluorouracil (5-FU) and camptothecin (CPT) as the model drugs, respectively.
For this purpose, Pluronic F-127 diacrylate macromer was synthesized and then self-assembled into the
micelles with their hydrophobic cores loading CPT. The CPT-loaded micelles we...

117. Simultaneous enhancements of toughness and tensile strength for thermoplastic/elastomer blends through interfacial photocrosslinking with UV radiation
本文报道了一种通过紫外光（UV）辐照在聚丙烯（PP）/马来酸酐接枝苯乙烯-b-（乙烯-co-丁烯）-苯乙烯嵌段共聚物（mSEBS）热塑性塑料/弹性体共混物中引入光交联界面的简单方法。在该方法中，以二苯甲酮（BP）作为光引发剂，三聚异氰酸三烯丙酯（TAIC）作为交联剂，在mSEBS相区与PP相区的界面处以及mSEBS相区中发生自由基交联反应。相较于未光交联的样品，有光交联界面结构的PP/mSEBS 共混物的韧性和拉伸强度由于光交联增强的界面黏附...

Surface modification of polyethylene by plasma pretreatment and UV-induced graft polymerization for improvement of antithrombogenicity
The purpose of this study was to enhance blood compatibility of polyethylene (PE) films. Glycidyl methacrylate (GMA) was grafted onto the surface of PE by Ar plasma pretreatment and UV-induced graft polymerization without photo-initiator, then heparin was immobilized onto the poly (glycidyl methacrylate) segments. The surface compositions and microstructure of GMA graft polymerized PE films were s...
