Influence of Chemical Interactions on the Macroscopic Spreading of a Maleic Anhydride Copolymer Melt

Dewetting of a droplet induced by the adsorption of surfactants on a glass substrate

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] The other process is the relatively slower wetting/dewetting process (sub-milliseconds to several hours) that reects the interaction between the droplet and the substrate. [14][15][16][17][18][19][20][21] In some cases, the translational motion of droplets induced by that interaction was reported. [22][23][24][25] For droplets of pure liquids, which contain no chemicals interacting with the substrate surface, the contact angle of the droplet on the ideal at surface relaxes to the equilibrium value q E determined by Young's equation:…”

Dynamic Wetting of Polyisoprene Melts: Influence of the End Group

“…The interaction of polymers with solid surfaces and their flow behavior in confined geometry are also of fundamental interest. For these reasons, the spreading of various polymer melts has been studied, for example, of polyisobutylene, , polyethylene (PE), − polystyrene (PS), ,, poly(amino siloxanes), and poly(dimethyl siloxane) (PDMS). − In contrast to liquids such as water or alcohols, polymer melts are not volatile and transport through the vapor phase is negligible. In this case of “dry wetting”, spreading only takes place by liquid flow.…”

Investigation on adhesion, interphases, and failure behaviour of cyclic butylene terephthalate (CBT®)/glass fiber composites

“…Electrokinetic investigations by an Electrokinetic analyser, EKA (A. Paar, AU, [1]) allow the estimation of both type and amount of dissociable surface functional groups on the fiber surfaces, as well as predicting adsorption processes influenced by interaction forces at the surface. The zeta potential is the voltage difference between a plane which is a short distance from the particle surface and the solvent beyond the double layer.…”
