ASGS 三步法调控取向结晶，制备拉伸强度 160 MPa 的强韧水凝胶
Strong hydrogels through precisely oriented crystallization regulation
AI 导读
研究提出 ASGS 策略制备结晶水凝胶，将碱诱导链活化（A）、超拉伸驱动取向（S）与甘油海水介导致密化（GS）结合，先以碱处理获得适度初始结晶度与细化晶核，再经超拉伸建立高度取向的链网络，最后致密化达到最高结晶度与高度取向的晶粒。
推荐理由
该工作用碱活化、超拉伸取向与甘油海水致密化三步调控结晶结构，为结晶水凝胶的力学强化提供了一条可放大的工艺路线。
创新点
借鉴工业热塑性加工，把碱活化、超拉伸取向与甘油海水致密化串联，实现对晶粒尺寸与取向的精确调控，使全水合水凝胶同时获得 160.0 MPa 拉伸强度与 26.4 kJ·m⁻² 断裂能。
