“…The main factors of mechanical energy dissipation of the tip and consequent phase change are the viscoelastic, adhesive and topographical properties of the region being examined. In addition, it allows to obtain new information about the polymers surface such as tribological data [3] , local contaminants [6] , morphology [17, , distribution of phases in blends and composites [41][42][43][44][45][46][47] , compatibility between the phases of polymer blends and interaction between nanocomposites phases [48][49][50][51][52][53][54] , polymeric chains conformation [7,38] , cross-link density [55][56][57] , dispersion of fillers in the polymeric matrix [10,12,16,48,49,[58][59][60][61][62][63][64][65][66][67][68][69] , among other applications.…”

AFM has been recognized as one of the most powerful tools for the analysis of surface morphologies because it creates three-dimensional images at angstrom and nano scale. This technique has been exhaustively used in the analyses of dispersion of nanometric components in nanocomposites and in polymer blends, because of the easiness of sample preparation and lower equipment maintenance costs compared to electron microscopy. In this review, contributions using AFM are described, with emphasis on the dispersion of nanofillers in polymeric matrices. It is aimed to show the importance of technical analysis for nanocomposites and polymer blends based on elastomers.

“…The same authors [49] studied the topography, elastic modulus, and adhesive energy maps of nanocomposites NR containing 5 phr (parts per hundred of rubber) of CNTs. According to the authors, such maps allow the characterization of different regions (CNTs and NR) through different properties of the materials.…”

“…The lower modulus distribution is Gaussian and symmetric, whereas the higher modulus distribution is broad and asymmetric. The lower modulus distribution is assigned to neat natural rubber according to the literature 46. By contrast, the higher modulus distribution is further divided into two: a distribution at 10 7 Pa and one at 10 7.5 Pa.…”

Nanodiamond glass is an amorphous solid consisting of nanodiamond as a nanoparticle. The several-nm-space between the nanodiamonds is filled with a medium that reversibly deforms and recovers. Hence, nanodiamonds linked in the medium are arranged in several-nm intervals. To prepare the nanodiamond glass, nanodiamonds are dispersed as inorganic nanoparticles with highly reactive functional groups into natural rubber as an incompressible medium exhibiting reversible deformation and recovery. Nanodiamond glass can be distinguished from nanodiamond-filled rubber, which exhibits ordinary entropic elasticity. Natural rubber particles dispersed in water (i.e., latex) are used to prepare nanodiamond glass, chemically embed nanodiamonds onto the surface of the natural rubber particles, and subsequently attach the surfaces together to achieve close packing of the nanodiamonds. Increasing the modulus of natural rubber constrained in the nanospaces ensures the energetic elasticity of nanodiamond glass. This work demonstrates that nanodiamond glass with energetic elasticity is a new research field.

“…Based on Hertz contact theory, three contact models have been established successively. The JohnsonKendall-Robert (JKR) model [13] describes the contact radius variation under different loads when the adhesion forces outside the area of contact are neglected and elastic stresses at the contact edge are infinite. In the Derjaguin-Muller-Toporov (DMT) model [14], adhesion forces outside the contact area are taken into account and do not cause surface deformation.…”
