It is known that when metals are evaporated on to softened polymer substrates, subsurface particulate structures are formed whose morphology is dependent on deposition parameters. Further, it was shown that the morphology is dependent on polymer-metal interaction. The present work demonstrates that the polymer-metal interaction can be brought about in inert polymers like PS by electron irradiation. The results indicate that the films deposited on PS irradiated to a dose of 20 and 25 kGy gives rise to smaller clusters with smaller inter-cluster separation, better suited for sensor applications. The induced polymer-metal interaction is attributed to the creation of free radicals due to the 8 MeV electron irradiation.</p>1 aPattabi, Manjunatha1 aGurumurthy, S., C.1 aSanjeev, Ganesh1 aGaikwad, A., B.  uhttps://library.ncl.res.in/content/electrical-behavior-silver-particulate-films-deposited-8-mev-electron-beam-irradiated-001844nas a2200253   4500008004100000022001400041245011700055210006900172260007300241300001400314490000800328520092800336653002501264653002301289653002201312653001301334653001101347653002301358100002401381700002301405700002001428700002001448856012201468       2011                        eng d  a0168-583X00aMorphological changes in nanoparticulate silver films due to electron beam irradiation of polystyrene substrates0 aMorphological changes in nanoparticulate silver films due to ele  aPO BOX 211, 1000 AE AMSTERDAM, NETHERLANDSbELSEVIER SCIENCE BVcJUL  a1534-15390 v2693 a<p>Results of the studies on the effect of 8 MeV electron beam irradiation of polystyrene substrates on the morphology of silver particulate films deposited at 455 K in a vacuum of 8 x 10(-6) Torr are reported. Optical absorption studies show the presence of transverse and longitudinal plasmon resonance for films deposited on irradiated polystyrene. Scanning electron microscopy reveals a decrease in particle size with smaller inter-particle separation for irradiated films. Larger clusters are formed in the case of films deposited on polystyrene after 300 h of irradiation. In this paper, we show that the morphology of silver nanoparticulate films can be modified by electron irradiation of inert polymer substrates like polystyrene. The change observed due to irradiation is attributed to the formation of free radicals, thereby altering the polymer-metal interaction. (C) 2011 Elsevier B.V.

Under the conditions of deposition, a sub-surface particulate structure is expected. It had been shown earlier that the morphology of the sub-surface particulate structure is dependent on polymer-metal interaction. In the present studies, an inert polymer like polystyrene (PS) is blended with an interacting polymer P4VP. The optical studies on the silver particulate films deposited on softened blends of PS/P4VP have been carried out. The results show a shift in plasmon resonance to higher wavelength with increasing P4VP concentration of the blends in comparison to that of the films deposited on pure PS. An X-ray photoelectron spectroscopy study at two different electron take off angles indicates the formation of subsurface particulate structures for films deposited on blends.</p>1 aGurumurthy, S., C.1 aPattabi, Manjunatha1 aKrishna, Shreedhar1 aGaikwad, A., B.  uhttps://library.ncl.res.in/content/preparation-and-characterization-silver-particulate-films-softened-polystyrene-and-poly4-0
