Molecular‐Tailored Ultrathin Hydrophobic Interphases for High‐Stable Zinc Metal Anodes

Carbon Energy, EarlyView.
Through a systematic comparison of the effects of alkyl small molecules with different backbone chain lengths and terminal structural distributions on the surface coverage and ordering of hydrophobic interfacial layers, the highly ordered FT‐SAMs are successfully constructed.
