As, in the market, poly (lactic acid) (PLA) is the most used polymer as an alternative to conventional plastics, and as functionalized chitin nanocrystals (CHNC) can provide structural and bioactive properties, their combination sounds promising in the preparation of functional nanocomposite films for sustainable packaging. Chitin nanocrystals were successfully modified via acylation using anhy...

This study evaluated the potential of using poly(lactic acid)/poly(e-caprolactone) (PLA/PCL) blends for fused filament fabrication (FFF) and assembly with pure PLA biomedical applications. PLA/PCL binary were meltblended in a twin-screw extruder at different ratios (20/80 to 80/20) then formed into filaments calibrated diameter FFF. The microstructure, surface properties, rheological mechanical...

Biodegradable poly(L-lactic acid) (PLA) fibrous scaffolds were prepared by electrospinning from a PLA melt containing poly(ethylene glycol) (PEG) as a plasticizer to obtain thinner fibers. The effects of PEG on the melt electrospinning of PLA were examined in terms of the melt viscosity and fiber diameter. Among the parameters, the content of PEG had a more significant effect on the average fib...

The effect of UV/Ozone irradiation together with the pretreatments using distilled water, hydrogen peroxide, and hydrogen peroxide/sodium silicate solutions on the dyeing depth of the poly(lactic acid), PLA, and poly(ethylene terephthalate), PET, fabrics by the application of disperse dyes were investigated and the results were compared with that of untreated fabrics. The results showed that th...

A wholly bio-composite based on poly (lactic acid) (PLA) and tannin acetate was successfully prepared via in situ reactive extrusion using dicumyl peroxide (DCP) to improve interfacial adhesion. The composites PLA with high acetylation degree exhibited increased molecular weight as compared extruded PLA, together the improvement of Young’s modulus tensile strength. rheology results showed that ...

Poly(lactic acid) (PLA) and PLA-poly(ethylene glycol) (PLA-PEG) nanoparticles containing resveratrol (RVT) were developed, and their antioxidant activity was evaluated. An analytical method using high performance liquid chromatography (HPLC)/photodiode array (PDA) detection was also developed and validated for RVT determination in nanoparticles. The mobile phase consisted of methanol : water (5...

Microcellular foams with unique cellular structures were prepared from poly(lactic acid) (PLA) and poly(butylene succinate-co-adipate) (PBSA) blends using a foam injection molding technique core-back operation. PLA PBSA are biopolymers that partially miscible each other. When these blended, several blend morphologies appeared found to be dependent on the ratio. The thermal rheological propertie...

Abstract The mechanical behavior, corrosion mechanisms, and cytocompatibility at the interface of magnesium wires reinforced poly-lactic acid polymer composites were studied by in vitro degradation study 180 days. Surface modification Mg plasma-electrolytic oxidation improved shear strength from 10.9 MPa to 26.3 which decreased 8 13.6 Mg/PLA PEO-Mg/PLA composites, respectively, after 42 days de...

Poly(lactic acid) (PLA) is the most used biopolymer for food packaging applications. Several strategies have been made to improve PLA properties for extending its applications in the packaging field. Melt blending approaches are gaining considerable interest since they are easy, cost-effective and readily available processing technologies at the industrial level. With a similar melting temperat...
