Abstract
Base-washed graphene-oxide which has been sequentially-modified by thiol-epoxy chemistry, results in materials with ice-nucleation activity. The role of hydro-philic/phobic grafts and polymers was evaluated with the most potent functioning at just 0.25 wt%. These 2-D hybrid materials may find use in cryopreservation and fundamental studies on ice formation.
摘要
经过硫醇-环氧化学顺序改性的碱洗氧化石墨烯会产生具有冰核活性的材料。亲水性/疏水性接枝物和聚合物的作用在仅0.25 wt%时就具有最强的功能。这些二维杂化材料可能会用于低温保存和冰形成的基础研究。
