METHOD OF MEASURING VISCOELASTICITY COEFFICIENTS OF MATERIAL AND DEVICE FOR MEASURING VISCOELASTICITY COEFFICIENTS OF MATERIAL

摘要

Commonly used coefficient in (G ', G ") when the information in the viscoelasticity of the adsorbent material, to display a viscoelastic possible to display to make, and also, that the viscoelastic coefficients of the material capable of calculating the viscoelastic coefficient in real time of the It provides an apparatus for measuring viscoelasticity coefficient of methods and materials. In a solution to the system (系) which material film is formed is adsorbed by the film immobilized on the piezoelectric element surface or a piezoelectric element, the N harmonic of the piezoelectric element, using at least two, in each of the N harmonic resonance frequency (F _S), using at least two of the half frequencies F _1, F ₂ (F ₂ F ₁₎ having a half of the conductance value of the conductance value of the resonance frequency, the mass load, wherein the viscoelastic wherein the viscoelastic wherein and viscoelasticity wherein the calculated and calculates a film viscoelastic modulus (G ') (storage modulus) and G "(loss modulus). ;
