Published: April 30, 2022

Abstract With the innovation of microelectronics technology, heat dissipation problem inside device will face a severe test. In this work, cellulose aerogel (CA) with highly enhanced thermal conductivity (TC) in vertical planes was successfully obtained by constructing vertically aligned silicon carbide nanowires (SiC NWs)/boron nitride (BN) network via ice template-assisted strategy. The unique structure SiC NWs connected to BN ensures that TC composite direction reaches 2.21 W m −1 K at low hybrid filler loading 16.69 wt%, which increased 890% compared pure epoxy (EP). addition, relying on porous CA, EP-based also showed higher than other comparative samples horizontal direction. Meanwhile, exhibits good electrically insulating volume electrical resistivity about 2.35 × 10 11 Ω cm and displays excellent electromagnetic wave absorption performance minimum reflection loss − 21.5 dB wide effective bandwidth (< dB) from 8.8 11.6 GHz. Therefore, work provides new strategy for manufacturing polymer-based composites multifunctional performances microelectronic packaging applications.

As a result of serious pollution in the water environment, sewage disposal has been receiving lot attention from industry. Metal-organic frameworks (MOFs) attract interest adsorption and separation due to their complex structures easily adjustable pore sizes. Magnetic MOFs inheriting advantages both large surface area easy recovery have great potentials pollutants. This paper reviews recent research progress on ions, dyes other contaminants by different types (magnetic non-magnetic MOFs) magnetic composites (Fe3O4@MOF) aqueous environments. The factors affecting pollutants, thermodynamic kinetic effects are discussed with detailed examples. Finally, challenges opportunities for further development elucidated.

Abstract Hydrogels are excellent for protecting membranes from oil fouling oil/water separation. However, conventional hydrogels including adhesive have a contradictory between high adhesion on and anti‐oil‐fouling ability. Herein, the design of an hydrogel is proposed by ingeniously integrating membranes, outstanding ability, ultrathin thickness suitable membrane decoration satisfactory durability, where inside‐out gradient distribution protocatechuic acid (PCA) hydrated calcium alginate (CaAlg) constructed. The innermost PCA enables to tightly adhere membranes. outermost CaAlg defends fouling. uniform integration PCA/CaAlg guarantee stability. Membranes decorated with demonstrate superhydrophilicity, anti‐fouling various oils, anti‐abrasion external damaging. achieve ultra‐stable efficient separation surfactant‐stabilized oil‐in‐water emulsions crude mixture most advanced cycling ability ≈100% flux recovery nearly zero irreversible This study provides new strategy designing toward practical applications.
