Crystallization of Poly(ε-caprolactone) in Poly(vinylidene fluoride)/Poly(ε-caprolactone) Blend
The crystallization behavior of poly(ε-caprolactone) (PCL) in a poly(vinylidene fluoride) (PVDF)/PCL blend as well as on a highly orientated PVDF substrate was studied by means of POM, DSC and TEM. The results show that the miscibility of the PVDF/PCL blend and the spherulitic morphology of PVDF varies with the blend ratio. For all the compositions, the pre-existing PVDF crystals accelerated th...
متن کاملPolymer geometry and Li+ conduction in poly(ethylene oxide)
We study the effect of molecular shape on Li+ conduction in dilute and concentrated polymer electrolytes (LiI : P (EO)n(3 ≤ n ≤ 100)). We model the migration-diffusion of interacting Li+ ions in the helical PEO molecule as Brownian motion in a field of electrical force. Our model demonstrates that ionic conductivity of the amorphous PE structure is increased by mechanical stretching due to the ...
متن کاملLi ion transport in an intercalated polymer electrolyte
Lithium ions solvated by polyethylene-oxide ~PEO! have been confined by intercalation within the galleries of an insulating, inorganic layered solid CdPS3 . The dc conductivity of this confined polymer electrolyte Cd0.75PS3Li0.5(PEO) displays a distinct change in the mechanism of conduction with temperature, exhibiting a crossover from an Arrhenius temperature dependence at low temperatures to ...
متن کاملPoly (ε-caprolactone) Fiber: An Overview
Poly (ε-caprolactone), (PCL) or simply polycaprolactone as it is usually referred to, is a synthetic biodegradable aliphatic polyester which has attracted considerable attention in recent years, notably in the biomedical areas of controlled-release drug delivery systems, absorbable surgical sutures, nerve guides, and three-dimensional (3-D) scaffolds, for use in tissue engineering. Various poly...
متن کاملMesoporous magnesium silicate-incorporated poly(ε-caprolactone)-poly(ethylene glycol)-poly(ε-caprolactone) bioactive composite beneficial to osteoblast behaviors
Mesoporous magnesium silicate (m-MS) and poly(ε-caprolactone)-poly(ethylene glycol)-poly(ε-caprolactone) (PCL-PEG-PCL) composite (m-MPC) was synthesized by solvent casting method. The results suggest that the mechanical properties of compressive strength and elastic modulus, as well as hydrophilicity, of the m-MPC increased with increase of m-MS content in the composites. In addition, the weigh...
