Influence of the ultrasound (US) on the formation of hydrogen bonds between the polymer and alumina was investigated in this research. It was expected that the positive/negative sound pressure changes of sonic wave led the weaking ability of the hydrogen bonds between alumina and polyacrylic acid under US exposune. The slurry solutions contained both alumina and polyacrylic acid(PAA) (molecular weight 250000) in 100ml water with weight ratio of 10:3, 20:3, and 30:3 was used. In the slurry solution, viscosity was measured when B type viscosity meter was used with 6, 12, 30, 60 rpm rotation after exposune of different frequency (28, 45, 100kHz) and the power of US (200, 250, and 300W/cm^2). It was found that hydrogen bonds were brooken by irradiating the US, because the viscosity of the solution decreases.
