WebSub-surface silver particulate films are deposited at a constant deposition rate of 0.4 nm/s on irradiated blends held at 455 K in a vacuum of 8 × 10−6 torr. The optical absorption studies indicate that the morphology of the nanoparticulate films can be tuned by electron beam irradiation of polymer blends. WebFigure 4. 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 *
