Polymer radical
WebIn a typical photochemical degradation, depending on the photon energy, radiation may electronically excite and thus make reactive some groups in the polymer (light, UV), or dissociate some its bonds to radicals (UV, RTG), or eject an electron from the molecule (RTG, γ-rays) giving rise to radical-ions (Guillet, 1980, 1985, Ranby & Rabek, 1975). WebIn searching for new and efficient mechanisms for moving or propelling nano-sized objects across a flat surface, we discuss the idea of using the periodically switchable topography of a certain class of polymer substrates. In this paper, we exploit the peculiar properties of diblock-copolymer and mixed brushes that can undergo transitions between very distinct …
