The possibilities of contact angle measurements of liquids at the solid surfaces under the different conditions for prediction of the most perspective directions of polymer application for individual and composite materials creation are considered. The surface free energy values at the «solid-gas» and «solid-liquid» interfaces as parameters of such prediction are exhibited. The correlation of the dispersive component of polymer surface energy with its free volume is founded. The new approach to estimation and comparison of the intensity of polymer adhesion to inorganic substrates is proposed and experimentally proved by measurements of tensile strength of corresponding composite materials. The possibility of alteration of «polymer-liquid» interfacial energy with surfactant mixed adsorption layers is demonstrated.

    The out diffusion of As is considered as one of the key issues of GaAs-based devices. We performed first-principles calculation to study the electronic structure distortion of HfO2 induced by out-diffused As. As diffused into oxygen vacancy of HfO2 results in several gap states ranging from 1.38...

    Side-view imaging of the contact angle between an extended planar solid surface and a liquid is problematic. Even when aligning the view perfectly parallel to the contact line, focusing one point of the contact line is not possible. We describe a new measurement technique for determining contact...
