Abstract Liquid metal (especially eutectic gallium indium, EGaIn) nanoparticle inks overcome the poor wettability of high surface tension EGaIn to elastomer substrates and show great potential in soft electronics. Normally, a sintering strategy is required break oxide shells nanoparticles (EGaIn NPs) achieve conductive paths. Herein, for first time, thermal‐sinterable NP are prepared by introducing thermal expansion microspheres (TEMs) into solution. Through mechanical pressure induced...

AgNW networks show high promise as a conductive material due to excellent flexibility, low resistance, transparency, and ease of large-scale preparation. However, the application has been hindered by their inherent characteristics, such easy oxidation degradation, chemical corrosion, structural instability at temperatures. In this study, dense SiO

The synthesized ionic liquids, 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) and 1-allyl-3-methylimidazolium ([AMIM]Cl) were used to treat cotton cellulose in order improve the efficiency of enzymatic hydrolysis. results showed that reducing sugar concentration from regenerated was improved 41.47 41.99 g/L, respectively, when pretreated by [BMIM]Cl [AMIM]Cl. However it only 18.14 g/L for untreated cellulose. It found dissolving capacity [AMIM]Cl better than at same temperature. Their...

Polyimide (PI)/titanium dioxide (TiO 2 ) composite nanofibers (NFs) with average diameters of 200–250 nm were synthesized via electrospinning. The total number density dipoles decreased significantly, owing to the porous structures and compact interface between TiO NPs PI matrix. All PI/TiO NFs maintain low dielectric constants losses. For example, -6% are all lower than 2.6, being exposed temperatures from 25°C 200°C. Meantime, losses below 0.005. ultraviolet (UV)-light shielding...
