“…16,[22][23][24] Over the last ten years, the need to lower the limits of spatial detection for addressing the biomolecular processes that control cells response to changes of neighboring environments, has given rise to the development of faster and more accurate force curve measurement technologies, in particular the Peak-Force AFM tapping mode (Bruker technology). 25,26 This mode of force curves acquisition allows a precise control of the sample to AFM probe interactions and a high resolution (nanometer scale) for AFM surface imaging. Methodologies differ according to e.g.…”

“…The restricted layer around silica exhibited weaker movement ability, which was confirmed by the experimental results of DSC, 106–108 dynamic mechanical thermal analysis 109,110 and NMR 111,112 . Moreover, the bound rubber layer exhibited a higher modulus compared with the pure matrix, which could be detected by AFM 113,114 . For example, Tian and co‐workers 113 investigated the interfacial interaction between nitrile‐butadiene rubber (NBR) molecules and pure silica or modified silica by grafting NBR molecules onto the surface of the AFM tip.…”

The concern regarding increasing oil consumption that originates from the high rolling resistance of automobiles has led to the development of green tires. The key enabling technique for preparing green tires involves the utilization of elastomer-silica nanocomposites. Elastomer-silica nanocomposites usually show low rolling resistance because of the intrinsic lubrication characteristics of siloxane and the excellent elastomer-modified silica interfacial interaction, making them ideal raw materials for a green tire. It is supposed that the comprehensive properties of rolling resistance can be further improved via continually optimizing the microstructures of elastomer-silica nanocomposites. Regulating silica dispersion, understanding the interface between elastomer and silica and building the quantitative correlation between the microstructure and the static/dynamic macro-mechanical properties are crucial in designing high-performance elastomer-silica nanocomposites. This review aims to summarize the recent progress of elastomer-silica nanocomposites from the point of view of silica dispersion, the elastomer-silica interface and the microstructure-mechanical connection, combining simulation and actual experimental findings. A short conclusion and an outlook on the current limitations and possible future research directions for constructing highperformance elastomer-silica nanocomposites for low-energy green tires are also presented.

“…Therefore, this work is devoted to the study of the mechanism of the exfoliation of HCM from NBR under uniaxial stretching using AFM. AFM allows one to perform high-resolution monitoring [11][12] of objects immediately in the process of their stretching [13][14][15].…”

The influence of hollow corundum microspheres on mechanical properties and wear resistance of nitrile butadiene rubber (NBR) with the lowest quantity of acrylonitrile (17-19%) have been studied. Results show that the abrasion resistance increased with increase in filler loadings at the two particle sizes investigated. Research of mechanical properties showed that strength at break decreased, while relative elongation at break increased with increase in microspheres loadings. Atomic force microscopy (AFM) was used to perform high-resolution imaging of surfaces of NBR composites. Microspheres exfoliation from NBR matrix at uniaxial stretching was studied with the use of special device compatible with AFM. The obtained AFM images demonstrate stretched fibrils bonded to the surface of microspheres.
