In this study, side-by-side bicomponent fibers were prepared by melt spinning using bio-based thermoplastic polyurethane (TPU) and TPU/polylactic acid (PLA) blends. The morphology, thermal mechanical properties of the investigated. To end, synthesis TPU biomass-based polyols preparation TPU/PLA blends preceded. Their morphological structural characteristics was confirmed through Fourier transfo...

Cellulose was modified by formic acid to prepare formyl cellulose (FC). The amount of groups in FC adjusted controlling the reaction time, temperature, and concentration. Then, used reinforce polylactic (PLA) films prepared solution casting. Scanning electron microscopy (SEM) shows that long rod-like particles were broken into short rods after formylation introduction made PLA surface rougher. ...

This study fabricated polylactic acid (PLA)/kenaf cellulose fiber biocomposite filaments via melt-extrusion process. Kenaf fibers (KF) were chemically extracted from locally grown kenaf plants and used as reinforcement. Moreover, the KF was then treated with tetraethyl orthosilicate (TEOS), so-called KFs, to improve compatibility between PLA matrix. Also, plasticizers (polyethylene glycol) inco...

An extruded composite food packaging film containing pectin, polylactic acids (PLAs) and nisin was developed to inhibit Listeria monocytogenes. The mechanical properties and surface structure of the film were also examined. Cells of L. monocytogenes were reduced by 2.1, 4.5 and 3.7 log units mL by the pectin plus PLA (pectin ⁄PLA) film containing nisin (1000 IU mL of tested liquid) in Brain Hea...

The aim of this work is to explore the manufacturing insulation structures using fused filament deposition biosourced materials. approach considers printing Polylactic acid (PLA) and PLA-flax (PF) varied infill density temperatures. Differential Scanning Calorimetry Thermal Gravimetry analysis are performed study thermal behaviour PLA PF derive weight content fibres within PF. measurements show...

Developing degradable filter membranes that inhibit bacterial infection for preventing particle matter and infectious disease has been a research hotspot. Here, the fiber of polylactic acid (PLA)/HKUST-1 with porous structure through entire matrix were prepared by electrospinning method. Due to HKUST-1 incorporation presence pore fiber, hydrophobicity had improved. The PLA/HKUST-1 exhibited goo...

The kinetics of crystallization Polylactic Acid (PLA) in the presence CO2 pressures from 1.5 to 4 MPa, has been studied by measuring optical absorbance evolution material with time. To perform this study, an own-designed pressure vessel provided windows used. non-destructive approach presented paper allows for obtaining very accurate crystallinity data as a function time wide range pressures. B...

This is a review of salient studies of sterilization, toxicity, biocompatibility, clinical applications and current work in the field of orthopaedics, using implants made of polylactic acid (PLA), polyglycolic acid (PGA) and their copolymers. The intrinsic nature of these biomaterials renders them suitable for applications where temporally slow releases of bioactive agents in situ may be requir...
