dc.description.abstractThe thermal behaviour of organometallic films was studied by thermogravimetric analysis (TGA) between 25 and 550-degrees-C at 10-degrees-C min-1. From the kinetic data obtained by TGA, it was found that the thermostability of these metal films depends on the metal and solvent. For palladium films the stability decreases in the following order: acetone, 2-butanone, dimethylformamide (DMF), 2-propanol, dimethyl sulphoxide (DMSO), tetrahydrofuran (THF), ethanol. For germanium films the stability decreases in the order acetone, 2-propanol, DMF, ethanol, 2-butanone, THF. For indium films the order of decreasing stability is DMF, ethanol, acetone, 2-butanone, DMSO, THF, 2-propanol.
dc.description.abstractThe variation in thermal stability is discussed in relation to the various solvents used and comparisons are made with poly(methyl methacrylates) containing the same metals; the activation energies of the thermal degradation are comparable within certain limits for the palladium, germanium and indium films. The reactions were found to be zero order for the thermal decomposition of these films. The pre-exponential factors and decomposition temperatures were determined.
