Single-walled carbon nanotubes were dispersed in an aqueous medium using surfactants and filtered to make entangled networks, called buckypaper (BP), the Raman spectra of BP samples revealed degree entanglement residual surfactant content. The temperature dependence G-band peak shift was found depend on reduction nanotube oxidation. electrical conductivity improved after removing increasing alignment, although resistivity still followed a variable range hopping conduction behavior....
Buckypapers (BPs) are thin films made up of carbon nanomaterials, such as single-walled nanotubes (SWCNTs) or mixtures SWCNTs with multi-walled (MWCNTs) vapor-grown nanofibers (VGCNFs). In this research, BPs were exposed to high electrical current densities under different environments, and the effects on nanotube BP breakdown observed. ambient conditions, SWCNT happened at around 430 °C a flash light. Mixed SWCNTs/MWCNTs SWCNTs/VGCNFs showed higher ignition temperatures over 500 °C. The...
Single-walled carbon nanotube (SWCNT) networks have become a subject of interest due to their ability support structural, thermal and electrical loadings, but date application has been hindered due, in large part, the inability model macroscopic responses an industrial product with any reasonable confidence. This paper seeks address relationship between macroscale conductivity nanostructure dense network composed SWCNTs presents uniquely formulated physics-based computational for...
Abstract Lead Titanate (FT) materials were prepared by a sol-gel process in an air atmosphere using lead acetate and titanium propoxide methoxyethanol as the precursor materials. FTIR Raman spectroscopy used to characterize various structural changes that occurred during stages of preparation. A new crystalline titanate phase was detected both spectral X-ray diffraction techniques when heating gelled material at 430°C. In-situ spectra measured high temperatures for resulting PT investigate...
Shear banding causes deformation to be heavily restricted in small volumes of a material, leading catastrophic failure materials. Yet how shear bands form is generally not known. Here, the authors follow entire process nanocrystalline ceramic (NCC) nanopillars ZrN using $i\phantom{\rule{0}{0ex}}n$ $s\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}u$ microscopy. The evidence obtained shows that deform through intermittent granular activities due nucleation and...
Buckypapers (BPs) are free standing thin sheets made of carbon nanotubes, such as single-walled nanotubes (SWCNTs) or multi-walled (MWCNTs) their mixtures. In this research, through in situ electrical resistance measurements, we studied the conductance changes nanotube networks (NTNs) various BP samples from complete immersion to evaporation using different chemical solvents. demonstrated a 20–30% decrease upon and almost full recovery after drying process. We found that by pre-stressing,...
We investigated the adsorption of sunset yellow (SY) in water by luffa sponge (LC)-based materials.Modified (MLC) and activated carbon (LAC) were prepared chemical modification H 3 PO 4 activation, respectively, followed charring.Dried LC adsorbs SY poorly through a physical process, with an equilibrium capacity 14 mg/g at 298 K. MLC LAC showed substantially improved SY.The maximum for reached 137 -9.78 times that raw -and this adsorbent had removal rate 99.9%.The was even higher, reaching...

The present study evaluated the properties of polymeric blend films obtained from chitosan and corn starch using glutaraldehyde as crosslinking agent glycerol plasticizer by casting/solvent evaporation method. Fourier transform infrared (FTIR) analyses confirmed that groups interactions in starch-chitosan were especially when agent. Differential scanning calorimetry (DSC) studies revealed an endothermic peak film at 98 oC corresponding to water evaporation. DSC also indicated moved higher...
Abstract Blends of polystyrene (PS) and poly(dimethylsiloxane) (PDMS), with without diblock copolymers (PS‐ b ‐PDMS), were prepared by melt mixing. The rheology behavior the blends was studied a capillary rheometer. morphology examined scanning electron microscopy. miscibility differential calorimetry. PS/PDMS modified addition PS‐ ‐PDMS investigated as function molar mass copolymers, viscosity ratios processing conditions. As investigated, observed melt‐blended pair unambiguously supported...
There are documented advantages to using carbon nanotubes (CNTs) in composites for various property enhancements. However, date, only limited studies have been conducted on of longer CNTs over 1 mm length. This study used long multiwalled (LMWCNTs) and their extended networks test multiple properties thermal conductivity, electrical mechanical strength, modulus then compared these those shorter multi‐walled (SMWCNTs). For fiber‐reinforced composites, the graphite paths from LMWCNTs matrix...
