Based on Diels–Alder reaction, linear bisfuranic terminated poly(tetramethylene oxide) and poly(p-dioxanone) were crosslinked by tris(2-maleimide ethyl)amine; this process was fully reversible under moderate conditions. All of the results indicate that co-network possesses typical advantages chemical physical crosslinking, peculiar thermal invertibility, shape memory effect self-healability.
Exposure to ambient fine particulate matter (PM2.5) increases risks for cardiovascular disorders (CVD). However, the mechanisms and components responsible effects are poorly understood. Based on our previous murine exposure studies, a translational pilot study was conducted in female residents of Jinchang Zhangye, China, test hypothesis that specific chemical component PM2.5 is associated CVD. Daily personal exposures 35 elements were measured two cities. A total 60 healthy nonsmoking adult...
Thermally-induced shape memory multiblock poly(ether-ester)s (PBSEGs) comprising crystallisable poly(butylene succinate) (PBS) hard segments and poly(ethylene glycol) (PEG) soft segments, were synthesized by polycondensation from succinic acid, 1,4-butanediol PEG diol. The copolymers characterized 1H-NMR, GPC, DSC DMA. analysis revealed that all PBSEGs prepared in this work are double-crystalline which ensure it to form separated crystalline domain determined the permanent temporary...
Abstract In order to improve the quality of micro-environment architectural complex and ensure that residents enjoy a healthy comfortable living experience, this paper uses Fluent simulation software simulate wind environment under three common layouts diffusion status PM2.5. On basis, green trees are added around pollution sources compare analyze adsorption blocking effect on particulate matter. The results showed after addition trees, community was optimized, concentration PM2.5 also...
Novel 2-ureido-4-pyrimidinone-functionalized poly(ε-caprolactone)/poly(p-dioxanone) interpenetrating polymer networks (PCU/PPDO IPNs) are developed via cross-linking star-shaped 4PCU and 4PPDO by self-complementary quadruple hydrogen bonding covalent in one-pot, respectively. PCL–PPDO co-networks (PCL–PPDO-CN) were also prepared for comparison. The structures of all the precursors determined 1H NMR, IPNs evaluated swelling tests. results differential scanning calorimetry (DSC) analysis...
Multi-shape polymers have recently attracted growing interest on account of their ability to switch between multiple shapes in a predetermined way. In this work, thermally induced shape-memory PPDO–PEG networks with well-defined architecture been designed and prepared by coupling hydroxyl-telechelic three-arm star-shaped PPDO PEG diol precursors HDI 1,2-dichloroethane. The molecular weight the feed ratio two affected gel content cross-link density network. DSC analysis indicated that...
A novel phosphorus-containing copolyester (PTTP), poly(trimethylene terephthalate) (PTT) with a bulky linking pendent group of 9,10-dihydro-10-[2,3-di(hydroxycarbonyl) propyl]-10-phosphaphenanthrene-10-oxide (DDP) was prepared, and its crystallization, crystal morphology interference color were investigated in this article for the first time. Differential scanning calorimeter (DSC) results showed that increase DDP content, melting point (Tm) crystallization ability PTTP decreased. WAXD...
Asthma is a global and increasingly prevalent disease. According to the World Health Organization, approximately 235 million people suffer from asthma. Studies suggest that fine particulate matter (PM2.5) can induce innate immune responses, promote allergic sensitization, exacerbate asthmatic symptoms airway hyper-responsiveness. Recently, severe asthma sensitization have been associated with T-helper cell type 17 (TH17) activation. Few studies investigated links between PM2.5 exposure,...
A series of poly(butylene terephthalate)-poly(butylene succinate) (PBT-PBS) copolyesters were synthesized by the melt chain-extension reaction dihydroxyl terminated PBT (HO-PBT-OH) and PBS (HO-PBS-OH) prepolymers using toluene-2,4-diisoyanate (TDI) as a chain extender. Transesterification between during has been investigated in detail. Both random block PBT-PBS copolymers can be changing prepolymers' molecular weights at given time temperature. The chemical structures sequence distributions...
Fractional crystallization, homogeneous nucleation of poly(ethylene glycol) (PEG) segment, and self-nucleation behavior PEG segment within miscible double crystalline poly(butylene succinate)-poly(ethylene (PBSEG) multiblock copolymers with different composition chain length were studied by differential scanning calorimetry (DSC). Surface morphology PBSEG10K content was investigated atomic force microscope (AFM). Different from di- or triblock copolymers, the microstructure confinement...
