[36,43] The three molecules, H 2 O, PVA, and PVP, produce free radicals after being irradiated by the electron accelerator (Figure S1a, Supporting Information). Semi-quantitative X-ray photoelectron spectroscopy (XPS) were conducted to investigate the radical reaction process for various doses of ionogel samples.…”

Skin, characterized by its distinctive gradient structure and interwoven fibers, possesses remarkable mechanical properties and highly sensitive attributes, enabling it to detect an extensive range of stimuli. Inspired by these inherent qualities, a pioneering approach involving the crosslinking of macromolecules through in situ electron beam irradiation (EBI) is proposed to fabricate gradient ionogels. Such a design offers remarkable mechanical properties, including excellent tensile properties (>1000%), exceptional toughness (100 MJ m−3), fatigue resistance, a broad temperature range (−65–200°C), and a distinctive gradient modulus change. Moreover, the ionogel sensor exhibits an ultra‐fast response time (60 ms) comparable to skin, an incredibly low detection limit (1 kPa), and an exceptionally wide detection range (1 kPa–1 MPa). The exceptional gradient ionogel material holds tremendous promise for applications in the field of smart sensors, presenting a distinct strategy for fabricating flexible gradient materials.

“…16,17 When hydrogels absorb water and swell, their mechanical properties are severely damaged, and assembly into sensors can result in distorted or interrupted signals. [18][19][20] Consequently, developing a hydrogel that doesn't swell in an environment with high water content is necessary.…”

“…To solve this problem, a hybrid anion exchange membrane with branched polymer structure was developed. Firstly, a branched polymer was synthesized by grafting allyltrimethylammonium chloride (TMA) onto polyvinyl alcohol (PVA) chains [19][20][21]. Afterwards, a hybrid anion exchange membrane was prepared via the sol-gel cross-linking of the grafted polymer and tetraethoxysilane (TEOS).…”

A branched polymer was prepared by grafting allyltrimethylammonium chloride onto polyvinyl alcohol (PVA) via free-radical polymerization. Afterwards, a series of hybrid membranes were prepared by sol-gel cross-linking between quaternary ammonium-PVA and tetraethoxysilane. The obtained membranes were characterized in terms of infrared spectroscopy, ion exchange capacity, water uptake, linear expansion ratio, and acid resistance. The thermal properties of the membranes were investigated as well. The diffusion dialysis performances of the membranes were tested by using a simulated feed solution containing HCl and FeCl 2 . The diffusion dialysis coefficients and the separation factors were much better than those of the commercial DF-120 membrane.
