Phase change materials (PCMs) represent an innovative solution to passively manage device temperature or store heat, taking advantage of the material phase transitions. In this work, attitude high density polyethylene (HDPE) for shape stabilization three selected organic PCMs with a melting close 55 °C was investigated. Composites PCM content in range 50-61 wt.% were produced by melt compounding, and lab-scale panels compression molding. The ability supporting olefinic matrix stabilize...
Films of silk fibroin cast from fibroin–water solutions at different casting temperatures and untreated or treated after with methanol, were characterized by differential scanning calorimetry (DSC), under static dynamic mode, thermogravimetric analysis mechanical thermal analysis. DSC revealed the presence a lower temperature endothermic phenomenon centered about 70 °C for as-prepared room film, other typical material parameters – glass transition, crystallization, degradation more less...
Composite acrylonitrile-butadiene-styrene (ABS)/carbon nanotubes (CNT) filaments at 1, 2, 4, 6 and 8 wt %, suitable for fused deposition modelling (FDM) were obtained by using a completely solvent-free process based on direct melt compounding extrusion. The optimal CNT content in the FDM was found to be %; this composite, detailed investigation of thermal, mechanical electrical properties performed. Presence ABS 3D-printed parts resulted significant enhancement tensile modulus strength,...
In recent years, additive manufacturing (AM) of ceramics has significantly advanced in terms the range equipment available, printing resolution and productivity. Most techniques involve use ceramic powders embedded an organic binder which is typically removed through a slow thermal debinding process. Herein, we prove for first time that ultra-rapid sintering are possible complex 3YSZ components produced using material extrusion technology. The printed were chemically debinded acetone thus...
Abstract The effect of thermal treatment on compression‐molded poly(L‐lactic acid) (PLLA) has been investigated by means viscosimetric molecular weight ( \documentclass{article}\pagestyle{empty}\begin{document}$$M_{w_v}$$\end{document} ) determination, differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMTA). Starting from two initial PLLAs, amorphous samples with different have obtained due to degradation occurring during the molding. crystallization capability...
The in vitro degradation of samples L- and D,L-lactic acid polymers, P(L)LA P(DL)LA respectively, having different molecular weights, morphology and/or geometry, has been studied through the determination viscometric weight, mass mechanical properties as function immersion time Ringer solution at 37 degrees C. In particular have compared kinetics P(L)LA, amorphous crystalline, weight sample geometry. From versus data, a rate defined, derivative best fitting normalized to polymer each time....
A paraffin wax was shape stabilized with 10 wt % of carbon nanotubes (CNTs) and dispersed in various concentrations an epoxy resin to develop a novel blend thermal energy storage capabilities. Thermogravimetric analysis showed that CNTs improve the stability paraffin, while differential scanning calorimetry kept its ability melt crystallize, enthalpy values almost proportional fraction. In contrast, noticeable loss observed for epoxy/wax blends without CNTs, which mainly attributed partial...
The effects of carbonaceous nanoparticles, such as graphene (GNP) and multiwall carbon nanotube (CNT) on the mechanical electrical properties acrylonitrile–butadiene–styrene (ABS) nanocomposites have been investigated. Samples with various filler loadings were produced by solvent free process. Composites ABS/GNP showed higher stiffness, better creep stability processability, but slightly lower tensile strength (low conductivity) when compared ABS/CNT nanocomposites. Tensile modulus,...

A chain-extender based on 1,1′-Carbonyl-Bis-Caprolactam (CBC) was melt compounded with a commercial Polyamide 6 (PA6) by using twin screw extruder. Rheological, thermal, and mechanical tests were performed the resulting materials to evaluate chain extension capability of CBC. Rheological pellets relative viscosity measurements solubilized samples evidenced an increase values amount, while opposite trend determined increasing high temperature residence time. Terminal group analysis confirmed...
