Gecko-inspired arrays of micropillars made a liquid crystalline elastomer display thermoswitchable adhesive behavior as consequence elongation changes caused by reorientation the mesogens at nematic-isotropic (N-I) phase transition.
Biocomposite films based on PLA reinforced with different β-TCP contents (10%, 20%, and 25%wt.) were fabricated via solvent casting immersed in SBF for 7, 14, 21 days. The bioactivity, morphological, thermal behavior of composites immersion studied using scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) microanalysis, weight loss (WL), diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential calorimetry (DSC), thermogravimetric analysis (TGA), gel...
This paper presents a method for manufacturing hybrid matrix composite material reinforced with woven carbon fiber that combines the properties of two thermoplastic polymers: PEEK (polyether-ether-ketone) and PEI (polyether-imide). The process involves multilayer architecture single hot-pressing consolidation step. Experimental tests — including uniaxial tensile tests, delamination in Mode I impact at low velocities were conducted to compare resulting laminate materials (PEEK/CF PEI/CF).The...
Purpose This paper aims to develop a novel strategy manufacture poly-lactic acid (PLA) filaments reinforced with Mg particles for fused filament fabrication of porous scaffolds biomedical applications. Design/methodology/approach The mixture PLA pellets and was extruded twice, the second time using precision extruder that produces zero porosity, constant diameter homogeneous dispersion particles. physico-chemical properties were carefully analysed determine influence on depolymerisation...
Selective laser sintering (SLS) of polymers has made possible the introduction lattice-based cells as building blocks polymer parts, allowing to obtain optimal specific properties. The actual mechanical performance an SLS part is strongly dependent on printing direction and shape. Nevertheless, macroscopic testing not usually due size restrictions fabricated part, it happens, for example, in materials. In this case, microscopic tests performed directly lattice surface become fundamental....
This manuscript explores the possibility of exploiting polymer morphology (thermal or flow-induced) as materials inherent template, and domain-selective plasma etching pattern developer, to obtain nanopatterned surfaces with different controlled geometries, a particular focus on nanofibrillar patterns. Oxidative treatment PET films has rendered patterned geometries depending crystallinity orientation sample time (or ratio). Homogeneous patterns either randomly distributed aligned nanofibrils...
Biocomposites made entirely by renewable biomass demonstrate excellent mechanical, hydrophobic and thermal properties thanks to rational cross-linking fiber reinforcement.
The feasibility to manufacture scaffolds of poly-lactic acid reinforced with Zn particles by fused filament fabrication is demonstrated for the first time. Filaments 2.85 mm in diameter PLA different weight fractions μm-sized - 1 wt.% Mg alloy (in range 3.5 17.5 wt.%) were manufactured a double extrusion method which standard followed precision filament-maker machine. constant diameter, negligible porosity and homogeneous reinforcement distribution obtained up 10.5%. It was found that...
The effect of the graphene nanoplateletets (GNP), at concentration 1, 5 and 10 wt %, in Poly ether ketone (PEEK) composite crystallization from melt during cold were investigated by differential scanning calorimetry (DSC) real time X-ray diffraction experiments. DSC results revealed a double GNP: (a) nucleating started higher temperatures (b) longer global due to restriction polymer chain mobility. This hindered mobility proved rheological behavior nanocomposites, because increase complex...
Polyetheretherketone (PEEK)/polyetherimide (PEI) blends (50/50, v/v) keeping the crystal phase of PEEK have been manufactured by alternate PEEK/PEI layer stacking. This strategy avoided complete miscibility both polymers, layers and PEI unmixed along sample thickness, as well promoting formation a smooth interfacial where were mixed. The properties this interface after processing at molten state different times was studied DSC, DMA, X-Ray synchrotron. These techniques allowed monitoring...
Bio-hybrid light-emitting diodes (Bio-HLEDs) based on color down-converting filters with fluorescent proteins (FPs) have achieved moderate efficiencies (50 lm/W) and stabilities (300 h) due to both thermal- photo-degradation. Here, we present a significant enhancement in efficiency (~130 stability (>150 days) using zero-thermal-quenching bio-phosphor design. This is shielding the FP surface hydrophilic polymer allowing their homogenous integration into network of light-guiding hydrophobic...
Macroscopic, robust, lyophobic, and biocompatible protein fiber mats derived from cottonseed isolate (CPI) as a renewable feedstock were successfully fabricated by electrospinning, with the incorporation of poly(ethylene oxide) (PEO) for spinnability improvement. Influences spinning solution concentration, CPI:PEO ratio, fiber-collecting velocity, epoxidized linseed oil (ELO) content on mat properties investigated. The collected at high speeds showed clear increases in tensile strength...
The development of polymer materials for real-world applications requires careful assessment material degradation over time and under environmental exposure. Such tests often necessitate frequent monitoring test specimens, which can become burdensome researchers. In this study, we present the application a collaborative robot to automate repetitive tasks involved in exposed solvent such as water. primary setup enables large number specimens immersed water bath, recording their mass,...
