High-quality reflective screens constitute an important part of multi-layer insulation materials. However, the metal foils currently used as thermal are easily oxidized in oxidizing environment. Nanoscale yttrium oxide exhibits high reflectivity near-infrared (NIR) region, well excellent stability The material also shows potential for application a high-temperature screen. A Y2O3 nanofiber membrane was successfully prepared by electrospinning synthetic polyacetylacetone‑yttrium (PAY)...
High-performance thermally insulating ceramic materials with excellent mechanical and thermal insulation properties are essential for management in extreme environments. In this work, SiO2 was introduced into the crystalline lattice grain boundary of TiO2 to inhibit its phase transition growth. Meanwhile, layered TiO2/SiO2 nanofiber membranes (TS NFMs) were designed prepared. The TS NFMs had lightweight (44 mg/cm3), high tensile strength (4.55 MPa), ultra-flexibility, low conductivity (31.5...
Hybridization by multi-components in an aerogel is efficient way to make nanoporous robust, high-temperature stable and multifunctional. While the formation of network a liquid-solid phase separation, solid-solid separation between multi-component likely be triggered enthalpy penalty, which would undermine synergistically effects. Here, this work presents copolymerized precursor that simultaneously incorporates two metals one precursor, efficiently suppress potential distinct components...
The inherent brittleness and hydrophilicity of ceramics pose a great challenge to designing reliable structure that can resist mechanical loads moisture in extreme conditions with high temperature humidity. Here, we report two-phase hydrophobic silica–zirconia composite ceramic nanofiber membrane (H-ZSNFM) exceptional robustness high-temperature resistance. For the dual-phasic nanofibers, amorphous silica blocked connection zirconia nanocrystals, lattice distortion was observed due Si ZrO2...
Ultralow-density (35–60 mg·cm–3) Yb2O3 nanofibrous membranes (YbFMs) with a multilayer structure were successfully prepared for the first time using Yb-acetylacetone coordination polymer as precursor. Thanks to high ceramic yield (62.1%) and excellent spinnability of precursor, YbFMs exhibited outstanding flexibility, which does not cause damage even when bent or knotted. The tensile strength was 1.69 MPa, maximum elongation could reach 33%. Notably, robust fatigue resistance, retaining...
Compared with single-component aerogels, hybrid aerogels multiple components possess enhanced properties, especially high thermal stabilities. Thermal stability improvement depends on the mixing between various components. In present research, a ZrO2/SiO2 aerogel was representatively chosen to study behaviors and resultant A series of were synthesized by using different sol–gel parameters shrinkage, nanopore collapse, crystallization behavior upon heat treatment. The hybridization weakly...
In this study, a new nanoporous material comprising NiMoO4 nanorods and Co3O4 nanoparticles derived from ZIF-67 supported by cellulose-based carbon aerogel (CA) has been successfully synthesized using two-step hydrothermal method. Due to its chemical composition, the large specific surface hierarchical porous structure, NiMoO4@Co3O4/CA ternary composite yields electrodes with an enhanced capacitance of 436.9 C/g at current density 0.5 A/g excellent rate capability 70.7% retention 5.0 A/g....
Low-cost urea formaldehyde resin (UF)/reactive halloysite nanotubes (HNTs) nanocomposite adhesive was prepared successfully via in situ polymerization. The HNTs were modified to improve its compatibility with polymer. XRD and FTIR results showed that physical chemical interaction between the polymer influenced structure of UF owing functional groups on HNTs. It is found from SEM images could be dispersed uniformly particles spherical. performance experiment confirmed thermal stability...
Zirconia (ZrO2) aerogels are potential candidates for use at temperatures higher than those attainable with silica aerogels. However, fabricating a robust ZrO2 aerogel high thermal stability is still challenge. The extreme electronegativity of Zr makes the hydrolysis and polycondensation zirconium precursors difficult to control, leading poor structural integrity unsatisfactory physical properties. In present research, we prepared by using synthetic precursor, namely...
