In nature, the superhydrophobic surfaces are almost in situ grown on its bulk phase under special environment. However, it is still a doubt how the bulk phase composition and external environment influence the structures and properties of in situ growth surfaces. To investigate the influence, a strategy is devised via using fluorine‐free benzoxazine as matrix model, selecting different metal chlorides to change the bulk phase composition of the matrix and utilizing different curing media to control the interface growth environment. It is found interestingly that the properties of in situ growth surfaces depend strongly on its bulk phase composition and external environment, and the superhydrophobic surface with controlled adhesion could be synthesized by in situ polymerization through one‐step curing and regulation of the bulk phase composition and growth environment. Moreover, the in situ growth superhydrophobic surface with controlled adhesion has high thermal stability, chemical stability, mechanical stability, and persistent stability. These findings not only show a unique idea for fabricating superhydrophobic surfaces with controlled adhesion, but also provide useful enlightenment for preparation and understanding of heterogeneous catalysts, sensors, and drag reducing materials.
