本研究是以動態測試(dynamic frequency sweep test)以及Cole-Cole plot來研究高分子熔體之非線性黏彈行為。發現可由動態測試可得阻尼函數,若將此關係應用於Larson模式來預測高分子熔體之流變性質是可行的。此外,發現高分子熔體在非線性黏彈範圍下,其彈性性質比黏性性質明顯。 This work deals with the investigation of the nonlinear viscoelastic behavior of polymer melts. The dymanic frequency sweep test was used to determine the damping function and the Cole-Cole plot was to analyzed the nonlinear viscoelastic behavior. It was found that the Larson model with the damping function's obtained in the above can describe the rheology of polymer melts in both the shear and elongation. With the Cole-Cole plot, the elastic component was found to be more important for nonlinear viscoelastic deformation than for linear deformation.
