Polysaccharide hydrogels possess weak mechanical properties because of their high water content. Herein, a simple, facile, and green method for preparing a polysaccharide hydrogel spanning a 100-fold range in ultimate stress (from 10 kPa to 1 MPa) with high water content (60–90%) is developed. Without modification or complicated preparation methods, hydrogels based on gellan gum can reach the ultimate stress at 1 MPa by utilizing the permeation and further cross-linking of the divalent solution. Moreover, the hydrogel pore size, biodegradation, and transmittance vary according to the concentration of the polymer and the divalent cations. Given the highly tunable mechanics, pore size, degradation, and transmittance properties of gellan gum hydrogel, it may be applicable for a wide range of biomaterial approaches and large-scale manufacturing.

从kPa到MPa：制备具有可调机械性能的多糖水凝胶的一种环保方法

多糖水凝胶由于水分含量高而具有较弱的机械性能。在此，开发了一种简单，简便且绿色的方法来制备具有高含水量（60-90％）的极限应力（从10 kPa到1 MPa）的100倍范围的多糖水凝胶。无需改性或复杂的制备方法，基于吉兰糖胶的水凝胶可通过利用二价溶液的渗透和进一步交联而在1 MPa时达到极限应力。而且，水凝胶的孔径，生物降解性和透射率根据聚合物和二价阳离子的浓度而变化。鉴于结冷胶水凝胶的高度可调的力学，孔径，降解和透射特性，它可能适用于多种生物材料方法和大规模生产。
