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...

Investigation of Thiol-ene Addition Reaction on Poly(isoprene) Under UV Irradiation: Synthesis of Graft Copolymers with "V"-Shaped Side Chains
Poly(isoprene) (PI) with pendant functional groups was successfully synthesized by thiol-ene addition reaction under 365 nm UV irradiation, and the functionalized PI was further modified and used to prepare graft copolymers with ‘‘V’’- shaped side chains. First, the pendant ASCH2CH(OH)CH2OH groups were introduced to PI by thiol-ene addition reaction between 1-thioglycerol a...

Grafting polymerization of acrylonitrile onto LDPE film: Study on grafting chain length and density with UV-vis spectroscopy
Grafting polymerization of acrylonitrile onto low density polyethylene film was studied further following the earlier work [1]. A novel and effective method was developed to directly determine the number of end-groups, i.e. phenyls at the end of grafted chains with UV-vis spectroscopy; according to the number of phenyl end-groups and the weight of grafted polymers, grafting chain length and d...

Facile Preparation of a Patterned, Aminated Polymer Surface by UV-light-induced Surface Aminolysis
Introducing amine functional groups on polymer surfaces is extremely important for studying various processes that involve polymer surfaces. We report a novel and extremely simple method for preparing a tertiary-amine-terminated poly(ethylene terephthalate) (PET) surface by using a UV-light-induced surface aminolysis reaction. X-ray photoelectron spectroscopy and attenuated total-reflection infrar...

化学收缩对纤维复合材料固化变形的影响
关键字：Curing deformation, Chemical shrinkage, Numerical simulation
复合材料成型的固化阶段是影响制品质量的关键环节之一。由于在固化过程中复合材料内部温度和固化度分布不均匀，故发生不同程度的热膨胀和固化收缩，从而引起热应力和固化收缩应力，导致脱模之后的变形，进而影响复合材料力学性能。
