PROBLEM TO BE SOLVED: To provide an antifouling structure capable of preventing adhesion of an organic compound or oil or the like, considering an environment.SOLUTION: The antifouling structure of an embodiment has an ultra-hydrophilic structure formed of irregularities with pitches of predetermined intervals, on a surface of a substrate, such as a steel plate 11 or a resin layer. Width (d) of a salient part 12 and width (w) of a recess part 13 on the irregularities have a ratio of 2:98-3:97, thereby the recess part 13 on which a water screen is formed, is formed. By the water screen, for example, an organic compound and oil or the like rebound, so that adhesion is prevented. As the result, biofilm generation due to adhesion of the organic compound and oil on a surface of a water channel for example, can be prevented.
【課題】環境に配慮した有機物や油等の付着を防止する防汚構造体を提供する。【解決手段】本実施例に係る防汚構造体は、基材である例えば鋼板11や樹脂層の表面に、所定間隔のピッチの凹凸を持って形成される超親水性構造を備えた防汚構造体であって、凹凸の凸部12の幅(d)と凹部13の幅(w)とを、2:98〜3:97の比率とすることにより、水膜が形成される凹部13を形成し、この水膜により例えば有機物や油等は反発することで、付着等の寄せ付けを防止し、この結果、例えば水路等の表面に有機物や油が付着することで起因するバイオフィルムの発生が防止される。【選択図】図1
