钴茂基金属聚两性离子兼顾水合与吸附，摩擦系数降至0.123
Synergizing Tunable Hydration and Robust Adsorption in Cobaltocenium‐Based Metallo‐Polyzwitterions for Superior Water Lubrication
AI 导读
研究团队通过硫醇-烯 click 聚合与分步后聚合改性，制备了以钴茂为阳离子、磺酸根为阴离子的金属聚两性离子 PZ-R，其两性离子侧基提供强水合，硫醚键与钴茂基团通过配位和静电作用促进在金属表面吸附。
推荐理由
原文给出钴茂基金属聚两性离子在水润滑中的摩擦系数与磨损数据，读者可据此判断其作为水基润滑添加剂的性能区间。
创新点
用钴茂阳离子与磺酸根构成金属聚两性离子，借硫醚与钴茂的配位和静电作用补上传统聚甜菜碱缺失的表面吸附，从而绕开水合与吸附之间的固有取舍。
