Abdi, Y. Khalilian, M. Arzi, E., Enhancement in photoinduced hydrophilicity ofTi02/CNT nanostructures by applying voltage. /. Phys. D Appl. Phys. 2011,44 255405/1-6. [Pg.453]

At the present time, most of the positive photoresists used in the manufacture of microcircuits consist of a low molecular weight phenolic resin and a photoactive dissolution inhibitor. This composite system is not readily soluble in aqueous base but becomes so upon irradiation with ultraviolet light. When this resist is exposed, the dissolution inhibitor, a diazoketone, undergoes a Wolff rearrangement followed by reaction with ambient water to produce a substituted indene carboxylic acid. This photoinduced transformation of the photoactive compound from a hydrophobic molecule to a hydrophillic carboxylic acid allows the resin to be rapidly dissolved by the developer.

The surface of PEEK can be protected by a hydrophilic high density nanometer-scaled layer on the surface by the photoinduced graft polymerization of 2-methacryloyloxyethyl phosphorylcholine. Photo-initiators are not needed, the reaction is a self-initiated surface graft polymerization. Actually, the diphenylketone moiety in the PEK polymer backbone acts as a photo-initiator similar to benzophenone. Since the photoinduced polymerization occurs only at... [Pg.167]
