Abstract

A pregrafting strategy is presented to construct covalent bridges between synthetic melanin, i.e., polydopamine (PDA), and hair for permanent hair dyeing. As a result, PDA is more uniformly distributed throughout the hair surface, and the dyed hair shows higher color intensity and better durability to washing than the control samples dyed with PDA directly at the same conditions.

摘要

提出了一种接枝前策略，在合成黑色素（即聚多巴胺，PDA）和头发之间构建共价键，实现永久性染发。结果表明，PDA 在头发表面的分布更加均匀，与相同条件下直接用 PDA 染色的对照样品相比，染色后的头发具有更高的颜色强度和更好的耐洗性。
