Abstract

Introducing new biomaterials is necessary for developing tissue engineering science. Soft tissue engineering need to high soft and stretchable properties and then innovation of bio rubbers based on natural materials is very important. In this research by using of the polymerization science and the chemical reaction between Xylitol, Dodecanedioic acid (DDA) and Lactic acid (LA) a new biopolymers were obtained. The samples were provided based on mole fraction of LA and weight percentages of bioglass nanoparticles (n-BG). Reaction between all of monomers were investigated by using Fourier-transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance (H-1 NMR) analysis. Also scanning electron microscope (SEM) and Mapping analysis show that the LA has had the necessary effectiveness on the morphology. The dynamic contact angle illustrated that hydrophilic properties of the polymeric samples have decreased in presence of LA and n-BG had positive effects in degrees of hydrophilic properties. The investigation of viscoelastic properties demonstrate that nanoparticles caused the storage modulus to increase and the presence of LA monomers has changed the glass transition temperature (T-g) from -2.6 degrees C to 21.7 degrees C in nanocomposite samples. Hydro-catalytic degradation test show that presence LA monomers decreases the degradation rate.
