The study aims to compare the lignin extraction methods of OPEFB using different solvents; soda and dioxane solvent, reinforcement effects in polylactic acid (PLA) bio-composite. Different method has been found produce with properties purity. yield also highly dependent on types solvents used process. Soda treatment had shown a good removal 17.4 % yield, but only 8.08 for treatment. In contrast...

In natural world, lignin is unique and the most abundant renewable carbon source after cellulose, therefore, more applications of adding commercial value of lignin are needed. Polylactic acid (PLA), which has the second highest consumption of bioplastic in the world, is a biodegradable composite with widely application in industry. A filler adding into PLA can decrease the cost of the composite...

Poly(lactic acid) (PLA) is the most promising biodegradable alternative to replace conventionalpetrochemical-based polymers in manufacturing high performance materials. Here we review main methods obtain polylactic acid and briefly discuss its functionalization application field of controlled drug release. We conducted a bibliographic search scientific databases summarized results research carr...

CO2-assisted polymer compression (CAPC) is an environmentally friendly processing method that uses CO2 to plasticize and crimp fibers at room temperature, enabling low-energy within a short time. In this study, CAPC was applied polylactic acid (PLA), carbon-neutral polymer. To evaluate the relationships between plasticization crystallinity degree of PLA, samples with different degrees were laye...

Nowadays, environmental awareness is more and important. Therefore, the importance of weight reduction creating a circular economy has increased. In this study, we foamed bio-based polylactic acid (PLA) with thermally expandable microspheres to create homogenous, compostable polymer foams. The acid-based sheet samples were produced flat extruder at 190 °C. We investigated temperature-dependent ...

Copper shows promising characteristics for applications in electrical sliding contacts. In this study, copper reinforced polylactic acid (PLA-copper) composites manufactured by fused deposition modeling (FDM). Wear behaviour of PLA-copper under dry conditions at three different temperature (20oC, 50oC, 70oC) was evaluated using pin-on-disc wear test equipment with attached heating module 5N loa...

BACKGROUND Polylactic acid (PLA) is considered to be a sustainable alternative to petroleum-based polymers for many applications. Using cellulose fiber to reinforce PLA is of great interest recently due to its complete biodegradability and potential improvement of the mechanical performance. However, the dispersion of hydrophilic cellulose fibers in the hydrophobic polymer matrix is usually poo...

Objective(s): In this study, drug loaded electrospun nanofibrous mats were prepared and drug release and mechanism from prepared nanofibers were investigated.  Materials and Methods: Paclitaxel (PTX) loaded polylactic acid (PLA) nanofibers were prepared by electrospinning. The effects of process parameters, such as PTX concentration, tip to collector distance, voltage, temperature and flow rate...

The antibacterial property of silver nanoparticles (Ag-NPs) and the antioxidant activity of Vitamin E have been combined by incorporation of these two active components within polylactic acid (PLA) nanofibers via electrospinning (PLA/Ag-NP/VitaminE nanofibers). The morphological and structural characterizations of PLA/Ag-NP/VitaminE nanofibers were performed by Scanning Electron Microscopy (SEM...

In consideration of the insolubility in water, sensitivity to heat and wide application in the oil and gas industry as a degradable additive, this paper introduces polylactic acid (PLA) to a self-degradable temporary sealing material (SDTSM) to investigate its effect on the SDTSM performance and evaluate its potential to improve the rheological properties and further promote the self-degradatio...
