“…In this paper, a dynamic mechanical analyzer (DMA) helped to determine the glass transition start temperature (T(g)) by taking the onset point of the sigmoidal change in the storage modulus, while transition temperature (T(trans)) was defined by the peak of tan δ, then the test and the calculated results indicated that the T(g) of SiO(2)/SMPU was 50.4 °C, and the T(trans) of SiO(2)/SMPU was 72.18 °C. …”

“…PUDs were characterized by pH, viscosity and particle size measurements, and the structure of the poly(urethane-urea) (PU) films was assessed by infra-red spectroscopy, differential scanning calorimetry, X-ray diffraction, thermal gravimetric analysis, plate–plate rheology and dynamic mechanical thermal analysis. The adhesion properties of the PUDs were measured by cross-hatch adhesion and T-peel test. …”

“…The effects of tethered PI, as well as of its chain length, on the mechanical and dynamic properties of rubber compounds were examined using a universal testing machine and dynamic mechanical analysis (DMA). In rubber sample preparation, the amount of PI(3)-TESPT (PI of 2900 g/mol) used in rubber compounding is equal to that of the reference sample with TESPT (S(TESPT)). …”

“…It is argued that this contradictory effect is caused by a selective localization of shorter CNTs onto GNPs due to strong π-π interactions when direct sonication is used. Dynamic mechanical analysis showed that the addition of nanofillers improved epoxy’s storage modulus by up to 84%, but this property is mostly insensitive to the different processing parameters. …”
