Abstract

SU-8 photoresist was used to construct 5 micrometer diameter pillar arrays on quartz crystal microbalance (QCM) surfaces spaced 10 micrometers centre to centre, with varying heights from 5 to 25 micrometers. Liquid responses of the patterned QCMs are reported for a series of glycerol-water mixtures to cover a broad density-viscosity product range. Hydrophobic chemical treatment of the patterned surfaces was also conducted, with contact angle measurements being studied to assess the wetting state. The frequency spectra were recorded and fitted to a Butterworh van Dyke model, allowing changes in frequency, resistance, dissipation and a Newtonian liquid check to be carried out.
