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...
Results concerning the influence of modification morphological and chemical characteristics ground tyre rubber (GTR) powders on mechanical properties polyethylene (HDPE or LDPE)/GTR blends are given. In order to improve interfacial adhesion between particles matrix, two oxidation treatments GTR powder by potassium permanganate (in solution) γ-irradiation air) were performed. Then, was incorporated in a HDPE matrix containing small amount maleic anhydride grafted (MAgPE). The effect studied....
Abstract High‐density polyethylene coated multiwalled carbon nanotubes (c‐MWNTs) and (MWNTs) have been dispersed into an ethylene vinyl acetate (EVA) copolymer by mechanical kneading. The effect of c‐MWNTs on tensile properties, thermo‐oxidative degradation, fire behavior has studied in comparison with virgin EVA EVA/MWNTs nanocomposites. Due to the better dispersion nanotubes, incorporation 3 wt % leads increase Young's modulus, cohesion combustion residues, a decrease peak heat‐release rate.
Abstract Nanocomposites based on an ethylene–vinyl acetate copolymer (27 wt.‐% vinyl acetate) and multiwall carbon nanotubes (MWNTs) have been prepared by melt blending their thermal degradation flame retardant properties evaluated. Special attention has paid to the influence of nanotube nature flammability more particularly time ignition (TTI) as measured cone calorimetry. It shown that there is a strong fire behaviour composites, especially previous MWNTs crushing proved substantially...
Abstract Polyurethanes cover a large range of materials exhibiting various physical and mechanical properties making them useful in different applications such as elastomers or biomaterials, for instance. The introduction ionic groups the polyurethane backbone opens way to new where can act crosslinkers that greatly modify final thermal materials. Furthermore, hydrophilicity chains be enhanced by presence species, so processed conventional dispersions even polar solvent water. As consequence...
The synergistic role of platinum and silica as a way to increase the final residue pyrolized silicone was investigated explained, giving new interpretations. Conditions were first set study thermal degradation silicones in presence based on simplest silicone/silica/platinum formulation. Numerous parameters, e.g., content or surface modifications, varied track their influences residues. A thorough DSC study, together with SEM/EDX Pyrolysis/GC-MS analyses, led us propose three-stage process....
The aim of this work was to study the properties polylatic acid/polyamide 11 (PLA/PA11) blends compatibilized with a multifunctionalized epoxide, Joncryl®, and evaluate performance such processed by Fused Deposition Modeling (FDM) 3D printing, compared those produced injection molding method. Blends containing different Joncryl contents from 0.5 3 wt% were prepared twin-screw extrusion. Evaluation thermal, rheological mechanical proved that acted as compatibilizer. Results showed effects on...
The present study investigates the effect of using lignin at nanoscale as new flame-retardant additive for polylactide (PLA). Lignin nanoparticles (LNP) were prepared from Kraft microparticles (LMP) through a dissolution-precipitation process. Both micro and nano lignins functionalized diethyl chlorophosphate (LMP-diEtP LNP-diEtP, respectively) (2-(triethoxysilyl)ethyl) phosphonate (LMP-SiP LNP-SiP, to enhance their in PLA. From use inductively coupled plasma (ICP) spectrometry, it can be...
