High‐resolution solid‐state NMR investigation of the filler–rubber interaction: 2. High‐speed [1H] magic‐angle spinning NMR spectroscopy in carbon‐black‐filled polybutadiene

Abstract: This work investigates the behaviour of elastomeric chains (polybutadienes of identical molecular weight but different microstructures) in the close vicinity of carbon black surfaces in order to attain a better understanding of the structure and properties of interphases. Elastomer–filler interactions are assessed through the study of the thermal properties and NMR relaxation characteristics of the corresponding materials. Three series of samples were compared: pure polymers, raw polymer–filler blends (filler … Show more

“…The CBG samples show much smaller values of Δ C p,rubber than those of the compounds. The fraction of tightly bound rubber is determined as ∼12 wt % based on the Δ C p values per rubber mass; this fraction is unable to undergo α relaxation. Similar results have been observed in 50 phr CB filled polybutylene system …”

“…At the molecular level, interaction at the polymer–silica interface changes the molecular mobility. The relative amount of material in the vicinity of the interface is expected to be inversely proportional to the size of the inclusion 22, 23…”

“…BaTiO 3 is usually in the form of ferroelectric ceramic particles, and Ba 0.6 Sr 0.4 TiO 3 was shown to be in the paraelectric phase at room temperature. In a previous study, the ‘distorted nano-region’ model was used to study the ferroelectric properties of Ba 0.6 Sr 0.4 TiO 3 ceramic [12]. ‘Polar nano-region’ is related to dielectric nonlinearity of BST in the paraelectric state, which is defined as a nanometer scale region with parallel oriented spontaneous polarization, which consists of each other acting as a giant dipole with slow relaxation frequency.…”
