Polyurethanes (PUs) represent a family of useful synthetic polymers (thermoplastic or thermosetting) obtained from diisocyanates and diols/polyols via polycondensation reactions.
Abstract Within the context of ALICE ITS3 collaboration, a set MAPS small-scale test structures were developed using 65 nm TPSCo CMOS imaging process with upgrade inner tracking system as its primary focus. One such sensor, Circuit Exploratoire (CE-65), and evolution CE-65v2, to explore charge collection properties for varying configurations including layer (standard, blanket, modified gap), pixel pitch (15, 18, 22.5 µm), geometry (square vs hexagonal/staggered). In this work...
PVDF electrospun membranes were prepared by employing different mixtures of solvents and diverse electrospinning parameters. A comprehensive investigation was carried out, including morphology, nanofiber diameter, crystallinity, β-phase fraction, piezoelectric response under external mechanical strain. It demonstrated that using low-toxicity DMSO as the solvent, with good morphology (bead-free, smooth surface, uniform nanofiber) can be obtained. All fabricated showed crystallinity fraction...
In this work, we explored a microwave-assisted glycolysis process to chemically recycle rigid polyurethane (PU) foam waste obtain single-phase product with suitable physio-chemical properties as secondary raw material for the preparation of new PU products. Such an approach was compared conventionally heated (ConvH) process, analyzing performances different catalysts. The use microwaves allowed 94% decrease in reaction time scale depolymerization, concurrent 45% reduction energy expense. By...
Abstract The effect of several nanofillers on thermal insulating properties polyurethane rigid foams (PUR) was analyzed. used differ for chemical nature and aspect ratio. We both pristine organically‐modified layered silicates (OMLS) inorganic spherical nanopowders. fillers were first dispersed in the polyol component through use sonication; then doped mixed with isocyanate. viscosity (polyether or polyester) degree dispersion filler also taken into account. results obtained showed that...
Rigid polyurethane foams (RPUFs) typically exhibit low thermal inertia, resulting in short ignition times and rapid flame spread. In this study, the fire phenomena of RPUFs were investigated using a multi-methodological approach to gain detailed insight into behaviour pentane- water-blown (PUR) as well pentane-blown polyisocyanurate (PIR) with densities ranging from 30 100 kg/m3. Thermophysical properties studied thermogravimetry (TG); flammability by means limiting oxygen index (LOI) cone...
ABSTRACT Several expandable graphites (EGs), differing in expansion volume but with the same mean size, are compared as flame retardants polyurethane (PUR) foams. Not only common sulfur‐intercalated investigated also a new one intercalated phosphorus. The main aim of this article is to understand which properties EG important for its retardancy effectiveness PUR Thermal stability, flammability, and fire behavior analyzed through limiting oxygen index cone calorimeter tests. Detailed...
The present work examines the influence of different carbon-based fillers on performance electrically conductive polymer blend composites. More specifically, we examined and compared effects graphene (GR), carbon nanotubes (CNTs) black (CB) a PC/ABS matrix by morphological investigation, electrical physic-mechanical characterization. Electrical analyses showed volume resistivity decreased when CNTs CB content were increased, although use melt-mixed GR did not really this property. For...
World plastic production has increased since industrial-scale began in the 1940s and while large amount of thermoplastic polymers can be effectively recycled re-used, undifferentiated or thermoset cannot, as a result, most these raw materials end up landfill energy recovery incinerators. The synthesis carbon nanomaterials from conversion waste is an alternative, promising approach owing to high added-value products. In particular, novel materials, could translate into interesting cheap...
With the next upgrade of ALICE inner tracking system (ITS3) as its primary focus, a set small MAPS test structures have been developed in 65 nm TPSCo CMOS process. The CE-65 focuses on characterisation analogue charge collection properties this technology. latest iteration, CE-65v2, was produced different processes (standard, with low-dose n-type blanket, and blanket gap between pixels), pixel pitches (15, 18, 22.5 $\mu$m), arrangements (square or staggered). comparatively large array size...
The use of graphene-based materials as co-catalysts are explored in the production active filter media for methanol gas-phase photo-oxidation. present work is intended to show relationship between composition and morphology photocatalytic systems with performance nanostructured mats. Three different have been used (graphene oxide, reduced graphene few-layer graphene) effect degrees oxidation has explored. comparison obtained results revealed that structure united affinity polymer matrix,...
A methodological framework implementing laboratory activities and life cycle assessment is presented applied to determine which parameters should be considered develop biobased rigid polyurethane foams for thermal insulation with improved environmental performances when compared their fossil counterparts. The was six partially (produced from bio-based polyols obtained azelaic acid and/or lignin) one fossil-based formulations. comprehensive set of impact categories investigated including...
