Abstract Currently, the increasing needs of conductive ionogels with intricate shapes and high processability by individual requirements next‐generation flexible electronics constitute significant challenges. Here, design highly processable is reported mechanical robustness self‐assembly a common triblock copolymer into precursor in functional mixed ionic liquids (ILs) containing conductivity‐enhancing polymerizable strength‐enhancing components. The subsequent situ polymerization forms...
A novel functional oligomer (Si-TFVE) with a siloxane backbone and thermally cross-linkable trifluorovinyl ether groups (−OCF═CF2) is reported here. When postpolymerized at high temperature, Si-TFVE converts to an amorphous cross-linked network (Si-PFCB), which shows dielectric constant of 2.33 loss below 2.1 × 10–3 30 MHz. Si-PFCB also excellent film uniformity the surface roughness less than 5.79 nm over 1 μm square area. Moreover, thermostability 5 wt % temperature 472 °C no obvious Tg...
Abstract Silver nanowires (AgNWs) are promising materials for the fabrication of high‐performance flexible transparent electrodes (FTEs) due to their excellent optoelectronic properties, mechanical flexibility, and low‐cost solution processability. However, one serious obstacle that hinders application AgNWs‐based is high contact resistance between AgNWs. Established methods reducing such as light‐induced welding, heat‐induced chemical welding require complex post‐treatment prepared AgNWs...
A thermally cross-linkable molecule composed of bis(trifluoromethyl)benzene and benzocyclobutene units (F1) was successfully prepared. Heating F1 (>200 °C) gave a cured resin, which showed dielectric constant (k) 2.47 at 30 MHz an average k value less than 2.51 in range frequencies from 0.15 to MHz. Such low values are comparable other polymeric low-k materials. For comparison, perfluorobenzene with groups (F2) also synthesized. The F2 exhibited 2.98, indicating that the introduction...
A new benzocyclobutene monomer with a fluorene backbone was synthesized, which can be thermally converted to cross-linked network low dielectric constant and high thermostability.
With the wide application of leather products, higher requirements are put forward for its flame retardancy. In this work, in order to improve retardant performance leather, phosphorus (PFR), nitrogen and intumescent (NPIFR), (NPFR) was added retanning process, respectively. The flame-retardant mechanism interaction relationship between studied. structure with confirmed by FT-IR. effects on properties were investigated limiting oxygen index (LOI), vertical burning test, cone calorimeter test...
Abstract Two kinds of treated fumed silica were prepared by treatment with either tetraphenylphenyltriethoxysilane (TPHTS) or both and hexamethyldisilazane (TPHMTS), used as reinforcing filler for silicone rubber. The resistance to irradiation the rubber obtained was investigated gamma ray dose 500 kGy in air. mechanical properties average molecular weight between crosslinking points (Mc) determined before after irradiation. results show that (TPHPHS) can effectively improve radiation while...
Aligned and cross-aligned silver nanowires (AgNWs) have emerged as a promising class of flexible transparent electrodes (FTEs) for broad applications in optoelectronic devices. However, the large-scale fabrication aligned AgNWs remains challenging due to special setups, rigid condition control, complex procedures. Here, we show that synergistic effect ionic-liquid-induced localized orientation at air–water interface subsequent superwettability-enhanced induced by spontaneous transfer leads...
A new curing system for high temperature vulcanized fluorosilicone rubber was studied by thermal cycloaddition reaction of trifluoroethylene aryl ether (TFVE). Fluorosilicone containing perfluorocyclobutyl (Si‐PFCB) prepared using the polysiloxane trifluorovinyl (Si‐TFVE) as base gum. The basic formula determined as: 100 parts Si‐TFVE (0.10%TFVE, mol), 50 fumed silica. process is follows: primary 180°C, 25 minutes; post‐curing 190°C, 3 hours. It found that mechanical properties (the tensile...
