This paper presents the development of wood flour (WF)-filled polylactic acid (PLA) composite filaments for a fused deposition modeling (FDM) process with the aim of application to 3D printing. The composite filament consists of wood flour (5 wt %) in a PLA matrix. The detailed formulation and characterization of the composite filament were investigated experimentally, including tensile propert...

In this research, we present a simple and cost effective soft lithographic process to fabricate PLA scaffolds for tissue engineering. In which, the negative photoresist JSR THB-120N was spun on a glass subtract followed by conventional UV lithographic processes to fabricate the master to cast the PDMS elastomeric mold. A thin poly(vinyl alcohol) (PVA) layer was used as a mode release such that ...

Drug-Grafted Polymers In article 2203078 by Huajiang Chen, Jinglei Wu, Shen Liu, and co-workers, polylactic acid (PLA)-dicumarol conjugates are synthesized grafting the hydroxyl of dicumarol to carboxyl PLA through esterification, then electrospinning them into nanofiber membranes. Dicumarol releases in response lipase attenuate peritendinous adhesion formation inhibiting Cx43/TGFβ1/Smad3 signa...

The current research determines the most recent developments in natural fibres reinforced polylactic acid composites. Polylactic (PLA) is derived from renewable resources and capable of degrading microorganisms, eliminating pollution caused by petrochemical-based plastic. PLA promising biodegradable material among polymers since it easily attacked bacteria decomposes easily, releasing H2O, CO2,...

Developing an eco-friendly industry based on green materials, sustainable technologies, and optimum processes with low environmental impact is a general societal goal, but this remains a considerable challenge to achieve. Despite the large number of research on green structural composites, limited investigation into the most appropriate manufacturing methodology to develop a structural material...

Gelatin-hydroxyapatite-polylactic acid (PLA) nanocomposites were synthesized using five different formulations. The nanocomposites were loaded with ibuprofen and the amount of drug in the carriers was determined. X-ray diffraction (XRD) analysis was conducted before and after drug loading to ensure the presence of ibuprofen on the nanocomposites. Drug delivery was evaluated in phosphate buffere...

Background: Innovative bioactive films incorporated with antimicrobial agents have been recently developed for food preservation. The aim of this study was to evaluate antibacterial activity of Polylactic Acid (PLA) films incorporated with Ziziphora clinopodioides Essential Oil (ZEO) and Ethanolic Propolis Extract (EPE) against some common food-borne pathogens. Methods: The volatile chemical...

The thermal behavior of the biodegradable Calotropis procera (CP) particle-reinforced polylactic acid (PLA) biocomposites was investigated. injection molding process used to make composites, and CP particle weight percentage varied during (0%, 5%, 10%, 15%, 20%). melt flow index, heat deflection temperature, Vicat softening point, properties composites were determined using dynamic mechanical t...

The possibility to replace damaged or diseased organs with arti®cial tissues engineered from a combination of living cells and biocompatible scaffolds is becoming a reality through multidisciplinary efforts. A number of critical components within this effort are being facilitated by microfabrication and MEMS approaches, including research tools to elucidate mechanisms which control cellular beh...
