Annotation:
Along with increasing demand and fields of application of nano- and microstructures formed in polymer materials, the demand of new polymer materials with different and specific properties that are not characteristic to conventional materials is also increasing. Nanocomposites meet such requirements. Scientific research, related to the development and application of nanocomposite materials characterized by specific properties, deserves great interest, as the use of nanoparticles provides polymers with new properties and increases the range of their application.
In this study, it is proposed to modify the light-sensitive photoresists based on novolac resin and diazonaphthoquinone by metal oxide and metal nanoparticles. It was shown that, when applying low-cost and simple production and periodical structure formation technology, new light-sensitive nanocomposite materials were created allowing control and changes in the properties of microstructures developed in thin coatings. Nanoparticles, when added to photoactive composition of diazonaphthoquinone and novolac, tend to alter its structure and optical properties, as well as geometrical parameters of the microstructures formed within its coatings.
