原位预聚策略为水凝胶 Xolography 打印按需调控粘度
Prepolymerization Enables On‐Demand Viscosity Tuning for Xolography of Soft Hydrogels
AI 导读
研究报道一种原位预聚策略，通过室温氧化还原反应把部分单体转化为高分子量线形链，仅靠反应时间就把粘度从 4.37 mPa s 调至 >90000 mPa s，跨度超过四个数量级，且不改变基础树脂组成。
推荐理由
通过室温氧化还原预聚调控树脂粘度，读者可看到它如何在不改配方的前提下抑制沉降并降低曝光剂量。
创新点
用室温氧化还原预聚在树脂内部生成线形高分子来调粘度，避免外加增稠剂改变最终材料，并把粘度调节与打印光剂量、沉降行为直接关联。
