Dynamics near the filler surface in natural rubber-silica nanocomposites

Effects of surface modification and thermal annealing on the interfacial dynamics in core–shell nanocomposites based on silica and adsorbed PDMS

“…The suitability of Eqs. (9) and (10) for calculating the different polymer fractions has been confirmed in NCs based on silica and various polymers [10,11,16,27].…”

“…to glass transition). On the other hand, Pissis and coworkers have suggested that the interfacial polymer is not completely immobile, since it demonstrates retarded dynamics, as recorded via an additional relaxation process, as compared to the bulk [8,9,16,17]. Moreover, they proposed that the increased interfacial layer thickness in polydimethylsiloxa ne(PDMS)/titania as compared to PDMS/silica nanocomposites [8,9,18] originates from the stronger particle-polymer hydrogen bonding.…”

Depercolation of aggregates upon polymer grafting in simplified industrial nanocomposites studied with dielectric spectroscopy

“…The investigation of local segmental dynamics in nanocomposites has been the goal of a large number of works in past years [13][14][15][16][17][18][19][20][21][22]. A slowing down of the α-process due to interaction or grafting between the polymer chain and the filler has been reported [14,16,17]. In this context, distinct contributions have been detected: one part of the chain segments is not affected by the filler, whereas an interfacial polymer layer with frozen dynamics at nanosecond time scales has been evidenced by solid-state NMR experiments, the so-called "glassy" fraction [13,14].…”

Novel one‐step synthesis of acrylonitrile butadiene rubber/bentonite nanocomposites with (3‐Mercaptopropyl)trimethoxysilane as a compatilizer

“…B30M30 has a low T g which is 221. 8 C, attributed to the aggregation of bentonite because of high concentration of MPTMS in the reaction [45]. …”
