0 +/- 0.1, alpha = 0.4 +/- 0.1, 1/z = 0.34 +/- 0.03, and p = 0.49 +/- 0.03, whereas for depositions carried out at 873 K amounted to beta = 0.3 +/- 0.3, alpha = 0.4 +/- 0.2, and 1/z = 0.0 +/- 0.2. Experimental error becomes important due to the flat morphology of the films inherent to the deposition technique. The change in the surface topography with the film temperature has been studied with the help of a simple Monte Carlo model which indicates the existence of two different growth regimes: a shadowing dominated see more growth, occurring at low temperatures, characterized by calculated values beta

= 1.00 +/- 0.04, alpha = 0.50 +/- 0.04, p = 0.46 +/- 0.01, and 1/z = 0.35 +/- 0.02 and a diffusion dominated growth that takes place at high temperatures as well as at low deposition rates, characterized by calculated values beta = 0.15 +/- 0.08, alpha = 0.33 +/- 0.04, and 1/z = 0.33 +/- 0.07. The good agreement obtained between the experimental and simulated parameters is discussed within the frame of the general characteristics of ABT-737 ic50 the deposition method.

research synthesized a functional dispersant, not only providing a good dispersion of carbon black (CB) but also possessing ultraviolet (UV)-curable and alkali-soluble properties, by a two-step process. Firstly, bisphenol-A epoxy diacrylate was reacted with benzophenone tetracarboxylic dianhydride SGC-CBP30 purchase at different molar ratios to obtain UV-curable/alkali-soluble resins. In the second step, these resins would possess dispersion ability of CB by reaction with an isocyanate-containing methacrylate. The prepared dispersants were evaluated by their dispersion ability and the light absorption property of CB. The results showed that one of the dispersants was able to disperse CB in the solvent

up to 10 wt % with a mean particle size about 100 nm. This particular dispersant had a moderate amount of amino-containing groups (such as urethane, amide, and imide) serving as anchoring sites on CB, and a sufficiently long chain (M(n) similar to 2600) to provide a steric repulsion among CB particles. The advantage of this CB/dispersant system is that no other curable resins are needed. By using a suitable photoinitiator, the present CB/dispersant system could reach a polymerization rate of 1.05 x 10(-3) (s(-1)), and a black pattern of 10 mu m in width on a glass substrate was obtained through an UV-lithography process.
