We evaluated the biocompatibility of a dimethylpolysiloxane-coated micro-device which had been designed for monitoring real-time bladder volume in previous studies. The extract assay with dimethylpolysiloxane which had been used for coating the micro-device to measure the bladder volume was performed as an in vitro cytotoxicity test. For in vivo bi...

A cholesterol-based organogelator bearing an anthraquinone imide (AQI) group was synthesized and characterized. It self-assembled into chiral gels in acetonitrile at low concentrations, which displayed a combination of electrochromic and chiroptical properties. Upon electrochemical reduction at −700 mV, the gel exhibited new absorption bands at aro...

The microstructure evolution of isotactic polypropylene (iPP) during annealing is reported. A few amount of poly(ethylene oxide) (PEO) which exhibits much lower melt temperature compared with iPP was introduced into iPP in this work. The crystalline structure of iPP was detected using differential scanning calorimetry (DSC) and wide-angle X-ray dif...

Fluorene-based polymers containing perfluorooctyl moieties were designed and synthesized. The high electronegativity and F…H-C interactions are present in the fluorinated polymers, which slightly induce blue-shift of UV-Vis absorption in film. The fluoropolymer films prepared from fluorinated solvents show lager contact angles than those prepared i...

A series of azobenzene containing side-on liquid crystalline ABA triblock copolymers were investigated. This triblock series possesses the same central liquid crystal block B and various lengths of the amorphous block A. Transmission electron microscopy (TEM), small angle X-rays and neutron scattering (SAXS and SANS) were used to study their morpho...

A novel encapsulated flame retardant containing phosphorus-nitrogen (MSMM-Al-P) was prepared by encapsulating with polyamide 66 (PA66-MSMM-Al-P) for the flame retardation of polyamide 6 (PA6). The structure and thermal properties of PA66-MSMM-Al-P were characterized by Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy and th...

The novel benzoxazine monomer containing phosphorus has been synthesized based on multifunctional amine route from bis(4-aminophenyl)phenylphosphate, p-cresol and formaldehyde. Subsequently, the benzoxazine monomer was thermo-cured into polybenzoxazine containing phosphorus. The chemical structures were identified by nuclear magnetic resonance (NMR...

A series of acrylate processing aid (ACR)-based ionomers with different lanthanide (La(III)) ion and acid contents were synthesized, and the interaction between ionomer and zinc stearate (ZnSt2) was investigated immediately after thermally annealing the ionomer/ZnSt2 (3/1 in weight) mixtures at 180°C. The results revealed that the ion groups in ion...

A one-step process to introduce both the aromatic and aliphatic primary amino groups with high chemoselectivity was developed. Triplet state acetone abstracts the hydrogen atoms from both the C-H bond of the polymeric film substrate and the O-H bond of phenol which is the building block and the amino group carrier. As a result, two kinds of free ra...

The present work aimed to study the interaction between plasma proteins and PVP-modified surfaces under more complex protein conditions. In the competitive adsorption of fibrinogen (Fg) and human serum albumin (HSA), the modified surfaces showed preferential adsorption of HSA. In 100% plasma, the amount of Fg adsorbed onto PVP-modified surfaces was...
