Morphology & Properties of Blends of Starch –caprolactone Blend
A binary blend of polycaprolactone and starch in 70:30 weight ratio (known under the tradename “Envar”) was blended in various weight ratios with organosolv lignin (L) and organosolv lignin butyrate (LB) by solvent casting and melt blending. The thermal transitions observed by DSC revealed behavior resembling that of native polycaprolactone (PCL). Depression in melting temperatures obtained by ...
متن کاملBioresorbable copolymer of L-lactide and ε-caprolactone for controlled paclitaxel delivery.
Bioresorbable, aliphatic polyesters are known in medicine where serve as orthopedic devices (e.g., rods, pins and screws) or sutures and staples in wound closure. Moreover, such materials are extensively stud- ied as scaffolds--three-dimensional structures for tissue engineering but also drug delivery systems (DDS). The aim of this study was to determine the release profile of paclitaxel, one o...
متن کاملCrystallization 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 کاملAmphiphilic copolymers of ε-caprolactone and γ-substituted ε- caprolactone. Synthesis and functionalization of poly(D,L-lactide) nanoparticles
Fully biodegradable and surface-functionalized poly(D,L-lactide) (PLA) nanoparticles have been prepared by a co-precipitation technique. Novel amphiphilic random copolyesters P(CL-co-γXCL) were synthesized by controlled copolymerization of ε-caprolactone and ε-caprolactone substituted in the γ-position by a hydrophilic X group, where X is either a cationic pyridinium (γPyCL) or a non-ionic hydr...
متن کاملMorphology, Nucleation, and Isothermal Crystallization Kinetics of Poly(-caprolactone) Mixed with a Polycarbonate/MWCNTs Masterbatch
In this study, nanocomposites were prepared by melt blending poly (ε-caprolactone) (PCL) with a (polycarbonate (PC)/multi-wall carbon nanotubes (MWCNTs)) masterbatch in a twin-screw extruder. The nanocomposites contained 0.5, 1.0, 2.0, and 4.0 wt % MWCNTs. Even though PCL and PC have been reported to be miscible, our DSC (Differential Scanning Calorimetry), SAXS (Small Angle X-ray Scattering), ...
