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 کاملEnzymatic degradation of Poly (ε-Caprolactone) and Starch blends bontaining SiO2 nanoparticle by Amyloglucosidase and α-Amylase
The aims of the study were to investigate the effect of poly(ε -caprolactone) (PCL) and nano- SiO2 within the thermoplastic starch (TPS) blends on the rate and extent of starch enzymatic hydrolysis using enzymes α-amylase and amyloglucosidase. The results of this study have revealed that blends with nano-SiO2 content at 6 wt% exhibited a significantly reduced rate and exte...

متن کامل(S)-6-Methyl-∊-caprolactone
The chiral title compound, C(7)H(12)O(2), a lactone derivative, features a seven-membered ring that adopts a chair conformation. The crystal structure is stabilized by weak C-H⋯O inter-actions occurring in the (100) plane. The absolute configuration was assigned on the basis of the enantioselective synthesis.
متن کاملBlends of Poly-(E-caprolactone) and Polysaccharides in Tissue Engineering Applications
Bioartificial blends of poly-( -caprolactone) (PCL) with a polysaccharide (starch, S; dextran, D; or gellan, G) (PCL/S, PCL/D, PCL/G 90.9/9.1 wt ratio) were prepared by a solution-precipitation technique and widely characterized by differential scanning calorimetry analysis (DSC), Fourier transform infrared-attenuated total reflectance spectroscopy (FTIR-ATR), optical microscopy (OM), wide-angl...
