Nanoindentation analysis and biological characteristics of chitosan-graft-poly(ε-caprolactone) copolymer scaffolds

Biological Properties of Blend Nanofibrous Scaffolds from Poly(caprolactone)-Chitosan-Poly(vinyl alcohol)

Preparation and Characterization of Aligned and Random Nanofibrous Nanocomposite Scaffolds of Poly (Vinyl Alcohol), Poly (e-Caprolactone) and Nanohydroxyapatite

Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite  (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...

Electrospinning collagen/chitosan/poly(L-lactic acid-co-ε-caprolactone) to form a vascular graft: mechanical and biological characterization.

For blood vessel tissue engineering, an ideal vascular graft should possess excellent biocompatibility and mechanical properties. For this study, a elastic material of poly (L-lactic acid-co-ε-caprolactone) (P(LLA-CL)), collagen and chitosan blended scaffold at different ratios were fabricated by electrospinning. Upon fabrication, the scaffolds were evaluated to determine the tensile strength, ...

Synthesis and Characterization of Poly(ethylene-co-vinyl alcohol)-graft-poly(ε-caprolactone)

Graft poly(ε-caprolactone)s (PCLs) with high graft density were synthesized by using random copolymer poly(ethylene-co-vinyl alcohol) (EVOH) to initiate ring-opening polymerization of ε-caprolactone, with and without cocatalyst Sn(Oct)2. The graft copolymer were characterized by IR, 1H and 13C NMR. The solution property and the crystallization behavior were also investigated.

Biodegradation and bioresorption of poly(ɛ-caprolactone) nanocomposite scaffolds.

A new type of hybrid three-dimensional scaffolds was prepared using poly(ɛ-caprolactone) (PCL) and chitosan-modified montmorillonite by solvent casting and particulate leaching method. The scaffolds were characterized by scanning electron microscopy coupled with energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and dynamic mechanical analysis to study the structural and mechanical ...
