Nanocomposite composed of organoclay )Cloisite 20A-C20A) and Poly lactic acid (PLA) was prepared by solvent casting method. Physical, mechanical, thermal, barrier and microstructure properties of the composite were studied. X-Ray diffraction (XRD) patterns and scanning electron microscopy (SEM) images revealed that the diffraction peak of nanoclay shifted to lower angles and the d-spacing betwe...

Nano fibrous membranes core-shell of poly(lactic acid) (PLA) and poly(?-caprolactone) (PCL), encapsulating 1 wt% curcumin, are fabricated by coaxial electrospinning technique. Morphology physical properties, as well the release studied compared with neat PLA PCL individually spinned. Morphological analysis shows for all samples obtainment fiber oriented in random way, without defect a narrow di...

The incorporation of fermented chitin nanowhiskers (FCHW) into poly(lactic acid) (PLA) increased the tensile modulus and strength PLA at expense ductility. brittleness can be overcome with use plasticizer such as polyethylene glycols (PEG). objective this study is to investigate effect FCHW on thermal properties incorporated PEG (PLA/PEG). PLA/PEG reinforced nanocomposites were prepared using s...

The effect of molecular weight on the crystallization behavior poly(lactic acid) (PLA) both isothermally and non-isothermally was studied using differential scanning calorimetry polarized optical microscopy. Two distinct crystal forms (? ??) were investigated under normal conditions for different weights. Using microscopy, growth rate spherulites measured nucleation estimated. Heterogeneous mor...

Abstract Integrated electrochemical sensors in which plasma‐treated poly(lactic acid) (PLA) single material acts as both selective coating layer and transductor (electrode) are prepared. Thus, three‐dimensional‐printed PLA specimens transformed into electroresponsive by applying a low‐pressure gas plasma treatment with three different gases: N 2 , O air (79% + 21% ). Although all treated sample...

The goal of this study is to explore a new strategy to improve the mechanical and hydrophobic properties of bacterial cellulose (BC) mats. The present work is the first to report the preparation of in situ self-assembled BC nanocomposites using electrospun hydrophobic poly(lactic acid) (PLA) or PLA/lipids (PLA/Lip) nanofiber mats as foundation for BC nanofiber growth. Adding electrospun PLA mat...
