Basing on recent works we discuss the issue relating wetting and hydrophilicity pointing out the topics enabling a fast progress in this area. Wetting is a phenomenon that is still the subject of intensive studies, both pure and applied. However, precise definitions of its molecular basis are still lacking and the static and dynamic macroscopic parameters should also be defined. An important role seems to be played by profound investigation on relaxation times of the primary elemental steps of the joined chemical and mechanical processes.

Opierając się na najnowszych pracach oryginalnych i przeglądowych, omówiliśmy podstawowe zagadnienia hydrofilowości i zwilżalności. Wskazaliśmy problemy, których rozwiązanie umożliwi szybkie postępy w tej dziedzinie. Zwilżalność należy do zjawisk o dużym znaczeniu, zarówno poznawczym, jak i praktycznym. Potrzebne jest sprecyzowanie definicji stosowanych pojęć i skali ich wartości. Należy dokładnie określić skalę zmian struktury wody, zarówno w pobliżu rozpuszczonych w niej cząsteczek, jak też w nanometrycznych oraz mikroskopowych obszarach granic międzyfazowych.
