Multifunctional aliphatic polyester nanofibers for tissue engineering
Electrospun fibers based on aliphatic polyesters, such as poly(ε-caprolactone) (PCL), have been widely used in regenerative medicine and drug delivery applications due to their biocompatibility, low cost and ease of fabrication. However, these aliphatic polyester fibers are hydrophobic in nature, resulting in poor wettability, and they lack functional groups for decorating the scaffold with che...
متن کاملAliphatic polyester polymer stars: synthesis, properties and applications in biomedicine and nanotechnology.
A critical review: the ring-opening polymerization of cyclic esters provides access to an array of biodegradable, bioassimilable and renewable polymeric materials. Building these aliphatic polyester polymers into larger macromolecular frameworks provides further control over polymer characteristics and opens up unique applications. Polymer stars, where multiple arms radiate from a single core m...
متن کاملAliphatic hyperbranched polyester: a new building block in the construction of multifunctional nanoparticles and nanocomposites.
Herein we report the design and synthesis of multifunctional hyperbranched polyester-based nanoparticles and nanocomposites with properties ranging from magnetic, fluorescence, antioxidant and X-ray contrast. The fabrication of these nanostructures was achieved using a novel aliphatic and biodegradable hyperbranched polyester (HBPE) synthesized from readily available diethyl malonate. The polym...
متن کاملAliphatic polyester-grafted starch composites by in situ
Catalyzed Ring-Opening Polymerization (ROP) of lactones, such as c-caprolactone and ii-vnlerolactone. ha\ been investigated for preparing aliphatic polycsrer-grafted corn starch compositions. The polynieri7ntion has been carried out either i n bulk (without solvent) or in I0 wtQ grunular starch i n toluene \uspension. aftcr adequate activation of thc starch wrface arnylosc/amylopectin hydroxyl ...
متن کاملBiodegradation and hydrolysis rate of aliphatic aromatic polyester
The biodegradation and hydrolysis rates of an aliphatic aromatic copolyester were measured in manure, food, and yard compost environments and in phosphate buffer solution (pH 1⁄4 8.0) and vermiculite at 58 C. Mineralization, molecular weight reduction, and structural changes determined by DSC, FTIR, and 1H NMR were used as indicators of the biodegradation and hydrolysis rates. Poly(butylene adi...
