Dielectric relaxation in nanocomposites based on thermoplastic polyimide and carbon nanofibres
The article presents the study of R-SOD 3% nanocomposite’s molecular mobility based on thermoplastic PI (R-SOD) with 3% of carbon nanofibres by dielectric method. Dielectric spectrum shows two processes of dipole polarisation relaxation: in the glassy state (local β process) and in the highly elasti...

| description | The article presents the study of R-SOD 3% nanocomposite’s molecular mobility based on thermoplastic PI (R-SOD) with 3% of carbon nanofibres by dielectric method. Dielectric spectrum shows two processes of dipole polarisation relaxation: in the glassy state (local β process) and in the highly elastic state (cooperative a process) related to molecular mobility of phenyl rings with polar —О— groups in diamine and dianhydride parts of a macromolecule and to segmented motion, respectively. |
