Polyurethane (PU) has been extensively used in vascular tissue engineering due to its outstanding mechanical performance and blood compatibility behavior. Here, biomimetic PU-based scaffolds were prepared using an electrospinning technique and gelatin-heparin was introduced as a surface modifier after oxygen plasma treatment to improve cell attachm...

The correlation between properties and the network structure of hydroxyl terminated polybutadiene (HTPB) based polyurethanes (PUs) was studied through linear and branched structure polymer matrixes formed by toluene diisocyanate (TDI) and an aliphatic polyisocyanate curing agent (N100). The curing reactions were monitored using differential scannin...

A novel trisilanol polyhedral oligomeric silsesquioxane-containing phosphorus (DPCP-TPOSS) was synthesized from trisilanolphenyl polyhedral oligomeric silsesquioxane (TPOSS) and diphenyl chlorophosphate. DPCP-TPOSS was characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), hydrogen nuclear magnetic resonance (1H-N...

Aqueous slurry free radical terpolymerization of acrylonitrile (AN) with vinyl acetate (VAc) and a constant amount of 2-acrylamido-2-methylpropane sulfunic acid (AMPS) using K2S2O8/NaHSO3 redox initiator was carried out in a 15-l continuous stirred tank reactor at constant temperature (60°C) and atmospheric pressure. A three-level response surface ...

Bioactive materials can attract calcium and phosphate ions in simulated body fluid (SBF) solution to mimic the composition of extracellular matrix (ECM). Rapid biodegradation rate of natural polymers in contact with water-based solutions and time-consuming process of mineralization in SBF led to using concentrated simulated media. Herein, gelatin-s...

Low molecular weight hyperbranched (HB) polyesters were synthesized via melt polymerization from trimethylolpropane and three aliphatic dicarboxylic acids, namely, succinic acid (SA), adipic acid (AA) and dodecanedioic acid (DA). The degrees of branching (DBs) ranged between 30% and 75% depending on the monomer ratio. Their DB, cyclic index and ter...

In this study, humic acid-immobilized-amine-modified polyacrylamide/sepiolite (Ha-Am-Paa-Sep) and phytic acid-modified polyacrylamide/sepiolite composites (Phy-Paa-Sep) were prepared and characterized for removal of Cu(II) and Ni(II) from aqueous solutions. The effects of contact time, initial concentration of adsorbent and metal ions, pH and tempe...

The three polymerizable monomers diethyl 9-(methacryloyloxy)-2-oxo-nonylphosphonate M1, 9-(methacryloyloxy)-2-oxo-nonylphosphonic acid M2 and diethyl 9-(methacryloyloxy)-nonylphosphonate M3 are examined for their free radical polymerization and copolymerization activity in methanol between 40 and 65°C. Polymerization proceeds readily through a ther...

This paper introduces a feasible method to improve the color value of bio-based polyamide 56 (PA56) fiber. Three types of whitening modifiers were introduced into the bio-based PA56 fibers by the in-situ polymerization method and melt blending method in order to improve the fiber color. The color values and mechanical properties of PA56 fibers were...
