Plant-derived polyphenol coating offers a promising route to fabricate functional surfaces for different substrate materials. However, almost all of the deposition approaches are time-consuming and involve inefficient processes, and the mechanisms behind the coating deposition are rarely understood. Herein, we report a rational methodology to achieve the rapid deposition of poly(caffeic acid) (
PCA
) by using H
2
O

as a trigger under the assistance of copper sulfate (CuSO
4
). The comparative monomer structure of
PCA
oxidation polymerization has illustrated a significant distinction in the reaction path for
PCA
coating deposition which has never been reported before. Until now, the unprecedented fast velocity for polyphenol coating has been obtained, and the
PCA
coating exhibits excellent homogeneity, spatiotemporal tunability, and firm stability. Moreover, three different types of filtration membranes, poly(vinylidene fluoride) microfiltration membrane (PVDF MF membrane), poly(ether sulfone) (
PES
) ultrafiltration (UF) hollow fiber membrane, and
PCA
-coated
PES
nanofiltration (NF) membrane, are all successfully dip-coated using H
2
O
2
-triggered
PCA
coating. Without synthetic complexities and intricate procedures, the formation of hydrophilic and homogeneous
PCA
aggregates on the surface and/or inside pore walls resulted in various membranes. The as-prepared
PCA
-coated PVDF MF membrane demonstrates excellent oil/water separation efficiency of less than 150 ppm and a flux recovery rate of approximately 90% even after five cycles. By one-step co-deposition of
PCA
and poly(2-ethyl-2-oxazoline) (PEtOx) on the
PES
UF membrane surface, hydrophilicity and biofouling resistance are implemented for efficient protein filtration. The
PES
NF membrane formed by the
PCA
layer exhibits high mono-/divalent ion selectivity and excellent chlorine resistance. Overall, these results represent a rapid and sustainable approach to tailor
PCA
coatings for versatile liquid separation processes.
