Preparation and Charaterization of Poly(1,4–Butanediol-Citrate) Elastomers and CdTe/Poly(1,4–Butanediol-Citrate) Composite Bioelastomers

Abstract:

Poly (1, 4–butanediol-citrate) elastomer (PBC) network polyester bioelastomer and high fluorescent CdTe/PBC nanocomposite bioelastomer were obtained by melting polycondensation with citric acid and monomer 1, 4-Butylene glycol as monomers. The structures and properties of the products were characterized by FTIR,DSC and fluorescent spectra, etc. It shows that the glass transition temperature of the PBC and CdTe/PBC were all lower than 0°C. Both PBC and CdTe/PBC were amorphous, transparent and highly flexible. They also have good hydrophilicity, degradation, and stability in dimensions. The biodegradation and water uptake of elastomers PBC and CdTe/PBC could be modulated by adjusting the monomers ratio and post-polymerization time. CdTe/PBC has high fluorescence and is expected to be useful in soft tissue engineering with the function of fluorescence biomarker.
