| 英文摘要 | A series of eco-friendly Mg/B-crosslinked sodium alginate/polyvinyl alcohol ionogels (Mg/B-SA/PVA) with ultrahigh adhesion, good conductivity, excellent mechanical properties and a wide temperature range of application are prepared under simple, mild conditions mainly from marine resources. SA and PVA are utilized to construct the hydrogel skeleton. Alkali treatment enhances the mechanical properties. The replacement of water with deep eutectic solvent (DES) facilitates the formation of the ionogel network. Crosslinking of SA with Mg2+ rather than traditional Ca2+ enhances flexibility and reduces brittleness. The incorporation of boron into the polymer network generates "cis-diol" structures, which significantly improves both the mechanical and adhesive properties of the ionogels. The Mg/B-SA/PVA ionogels exhibit ultra-high adhesion strength (548.25 kPa). The M/G ratio of SA plays a crucial role in the performance of the ionogels, and an optimal ratio of 1:1 was identified. Mg/ B-DES system decouples the mechano-chemical effects caused by different molecular building blocks, achieving a balance between mechanical toughness (513 %, 0.60 MPa), extensibility (5-fold), conductivity (0.82 S.m-1), and adhesion strength (203.83 kPa). The energy dispersive X-Ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) results demonstrate that both boron and magnesium crosslinking elements exhibit a uniform distribution within the ionogel. |
