For the purpose of fabricating electrically conductive composites via fused filament fabrication (FFF) technique whose properties were compared with injection-moulded properties, poly(lactic acid) (PLA) and polycaprolactone (PCL) mixed different contents graphene nanoplatelets (GNP). The wettability, morphological, rheological, thermal, mechanical, electrical 3D-printed samples investigated. microstructural images showed selective localization GNPs in PCL nodules that are dispersed PLA...
In this study, a representative set of thermally thin materials including various lignocellulosic and synthetic fabrics, dense wood, polypropylene sheets were tested using cone calorimeter at different heat fluxes. Time-to-ignition, critical flux, peak release rate (pHRR) the main parameters considered. It appears that flammability is firstly monitored by sample weight. Especially, while burning thermally-thin does never reach steady state in calorimeter, their pHRR to be mainly driven fire...
The influence of processing intumescent bio-based poly(lactic acid) (PLA) composites by injection and fused filament fabrication (FFF) was evaluated. A raw (ANa) two acidic-activated (AH2 AH5) montmorillonites were added to the formulation, composed lignin ammonium polyphosphate, in order evaluate strength nature (Brønsted or Lewis) their acidic sites on fire behavior composites. thermal stability volatile degradation products assessed. injected 3D-printed submitted cone calorimeter (CC),...
Percutaneous closure of paravalvular leak (PVL) has emerged as an alternative to surgical management in selected cases. Achieving complete PVL occlusion, while respecting prosthesis function remains challenging. A multimodal imaging analysis morphology before and during the procedure is mandatory select appropriate device. We aim explore additional value 3D printing predicting device related adverse events including mechanical valve leaflet blockade, risk embolization residual shunting.From...
The incorporation of fly ash in polybutyl succinate (PBS) and adipate terephtalate (PBAT) the partial replacement ammonium polyphosphate and/or melamine is evaluated present work. Furthermore, influence surface modification with two silanes titanate coupling agents was also studied. Cone calorimeter experiments, pyrolysis combustion flow calorimeters (PCFCs), UL94V tests were used to assess fire performance composites. Scanning electronic microscopy, X-microanalysis, X-ray diffractometry...
ABSTRACT The aim of this study was to develop flexible sensors with cotton and polyester knit fabrics as substrates coated polyaniline (PAni) doped hydrochloric acid or phosphoric acid. deposition PAni onto the knit, polymerization synthesis, doping aniline monomer were performed via an in situ reaction. Graphite dispersion used obtain electrodes sensors, which prepared differently for each substrate. main evaluation carried out a humidity chamber under nitrogen (N 2 ) application drying...
Abstract Biobased flame‐retardant polylactic acid composites were prepared using ammonium polyphosphate (AP), lignin, and a raw montmorillonite (ANa) as the intumescent formulation. The concentration of AP ANa was varied in order to study its influence on flammability properties composites. samples submitted cone calorimeter test, thermogravimetric analysis coupled Fourier‐transform infrared spectroscopy (TGA‐FTIR), limiting oxygen index (LOI), UL‐94 vertical burn. residues analysed through...
For the first time, double electrical percolation threshold was obtained in polylactide (PLA)/polycaprolactone (PCL)/graphene nanoplatelet (GNP) composite systems, prepared by compression moulding and fused filament fabrication (FFF). Using scanning electron microscopy (SEM) atomic force (AFM), localisation of GNP, as well morphology PLA PCL phases, were evaluated correlated with conductivity results estimated four-point probe method measurements. The solvent extraction used to confirm...
Guided bone regeneration involves excluding non-osteogenic cells from the surrounding soft tissues and allowing osteogenic originating native to inhabit defect. The aim of this work was fabricate, analyze antibiofilm activity evaluate in vivo biological response poly (lactic-co-glycolic acid) (PLGA) electrospun membranes incorporated with tea tree oil furan-2(5H)-one. Samples were exposed Streptococcus mutans culture after 48 h incubation, biofilm evaluated by colony forming units (CFU/mL)...
Abstract The aim of this research was to investigate the activity functionalized PLGA electrospun membranes in preventing Streptococcus mutans biofilm formation. nanofibres were with additives Melaleuca alternifolia and Coffea canephora essential oils, furan‐2( 5H )‐one, a novel synthetic butyrolactam, three concentrations (0.002%, 0.004%, 0.008% w/v). Samples characterized by SEM, FTIR‐ATR, GC–MS exposed S. cultures. Planktonic growth determined following 24‐ 48‐h incubation period...
