Who can tell me these two conceptions

    What is "the disjoining pressure" and What is "the Hamaker function".

    Where did you read about these concepts ?
    Can you give a reference to a text where they appeared ?

    This paper might help to explain the Hamaker function (and Hamaker equation, Hamaker constants).

    As for disjoining pressure - see "http://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=JAPIAU000098000012124906000001&idtype=cvips&gifs=yes [Broken]"

    Also see - Lifsh!tz theory (where ! = i, in order to avoid auto-censor :rolleyes:)

    van der Waals Interaction, Surface Free Energies, and Contact Angles: Dispersive Polymers and Liquids

    which mentions Lifsh!tz theory and Hamaker equation and constants.

    See also - On the calculation of disjoining pressure isotherms for nonaqueous films.
