Measuring the viscosity of films by thermomechanical analysis: application to metal organic precursor films of functional oxides

We have developed a new method to measure the viscosity of micrometric films by thermomechanical analysis with a hemispherical probe of millimetric diameter. The loading curve (displacement vs. time) recorded as the probe tip crosses the whole film at constant load until it touches the substrate is...

The loading curve (displacement vs. time) recorded as the probe tip crosses the whole film at constant load until it touches the substrate is fitted to a theoretical curve shape that has been obtained after solving the problem of liquid flow under the probe tip. The method has been validated by measuring the viscosity of rosin films. It has been applied to analyze the thermal evolution of unstable liquid films that appear on Ba propionate, Ce(III) propionate and a low-fluorine precursor film of YBa2Cu3O6+x. During pyrolysis of the last two films, viscosity first diminishes due to heating and then it increases as solid oxide particles are formed inside the liquid.This work has been partially funded by the Spanish Programa Nacional de Materiales through projects MAT2014-51778-C2-1-R, MAT2014-51778-C2-2-R, RTI2018-095853-B-C21, RTI2018-095853-B-C22, PID2021-127297OB-C21 and PID2021-127297OB-C21, co-financed by the European Regional Development Fund, MCIU/AEI/FEDER, UE and also by the Generalitat de Catalunya contract No. 2017-SGR001519 and by the Universitat de Girona contract No. MPCUdG2016/059.
