Can ultrasonic irradiation be used to increase the bending and tensile deformations of thermoplastic polymer?
I know ultrasonic irradiation can be used to soften metal materials, but I could not find any literatures on the influence on plastic. I also know that when a high enough ultrasonic energy is applied, the thermoplastic polymer material will melt, but what will be the situation if the power is not high enough and will the polymer get softened as well?
Ultrasonic waves are have considerably high ferquency. They in general denature polymer fragments. Could you please specify the primary intention of using ultrasound to polymer systems?
What is the main objective of using it onto thermoplastics.?
In such conditions, chances of polymer degradation are very high and will change the materials property drastically due to change in molecular weight.
for knowing the influence of sonication on a thermoplastic, you can see some published works, Moore group,UIUC. As Omkar said, in general, these linear polymerw will be degraded under sonication.
You can see this review paper: May, P.A.; Moore, J.S. "Polymer mechanochemistry: techniques to generate molecular force via elongational flows". Chem. Soc. Rev. 2013, 42, 7497. DOI: 10.1039/C2CS35463B.
