Dispersive, specific and total surface energies for carbon fibres and polymers. The surface energy of the individual components can now be used to estimate the interaction between each polymer-fibre pair. Such an estimation is obtained from the calculation of the work of adhesion, WA by applying Eq.1. WA total = 2(1 d d* 2) 1/2 + 2(1 sp *
WebBy optimizing the combination of two scCO2-assisted green processes: the foaming and the micro- nanoimprinting, it was possible to obtain white and surface-functionalized PMMA samples in a one-step process. Taking inspiration from the natural model of the white beetle (Cyphochilus) in fact, a porous, highly reflecting structure was obtained via ... WebNov 28, 2024 · Direct fluorination of polymers is a widely utilized technique for chemical modification. Such introduction of fluorine into the chemical structure of polymeric materials leads to laminates with highly fluorinated surface layer.
