Cov yam ntxwv ntawm cov kua interfacial nro yog ze ze rau cov hauv qab no:
1. Nws muaj feem xyuam rau cov khoom ntawm cov kua nws tus kheej, xws li polarity, molecular loj, hom intermolecular rog, thiab seb puas muaj hydrogen bonds.
2. Nws muaj feem xyuam rau cov khoom ntawm cov khoom siv interface, tshwj xeeb tshaj yog thaum lub interface yog ib qho khoom. Nws yog feem ntau ntseeg (sim tau txais) tias nws tsuas yog cuam tshuam rau txheej txheej ntawm cov atoms los yog cov pab pawg ua haujlwm ntawm cov khoom saum npoo, thiab muaj me ntsis ua rau cov txheej hauv cov atoms.
Yog hais tias nws yog ib qho khoom-kua interface, nws kuj muaj feem xyuam rau qhov roughness ntawm cov khoom nto.
