“…In 1982, the scanning tunnelling microscope (STM) was developed as a tool to image metallic and semiconducting surfaces with high resolution [1,9,51,55,88]. This discovery later prompted the development of several advanced high-resolution imaging techniques, which scan point probes in a raster pattern across the sample surface to detect various interaction forces.…”

“…It is used not only in physical, chemical, biological, medical and material research laboratories, but also for product development and quality control. The success of the AFM is attributed to the high resolution and the versatility, with which it can map not only the topography of sample surfaces in the sub-micrometre scale, but also physical properties depending on the interaction forces between the tip and the sample surface [26,32,51,55,65]. As elaborated by Starostina and West [88] and Prater et al [76], the AFM is capable of producing 3D topographical information from the Å to the lm level with high resolution.…”

“…To create an image, the tip is brought into close contact with the sample and raster-scanned over the surface, causing the cantilever to deflect because of a change in surface topography or other interaction forces. The cantilever deflection is detected via a laser beam that is deflected off the cantilever's back side into a position-sensitive photodiode detector [1,51,55,76,88] as shown in Fig. 1.…”

The search for innovative solutions for the reuse of solid residues has intensified with growing environmental issues and the increasing cost of most raw materials, leading to the design of eco-friendly composite materials, such as wood-plastic composites (WPCs). These materials combine the stability of wood fibres with the durability of plastic, allowing for a wide range of applications, whilst simultaneously offering the possibility of utilising waste products from the forest/wood industry and recycled plastic. Waste products that otherwise incur cost for disposal therefore become a sustainable material resource for new products. Natural fibres offer a number of advantages over synthetic fibres and are seen as a ''green'' alternative to other reinforcements. Commonly, the fibrematrix adhesion in WPCs is improved by using compatibilisers that bond to the polar wood fibres and the non-polar polymer matrix. However, the problem with these is that good dispersion is not always achieved as it depends on the adhesion properties of three individual components in the WPC, which might lead to poor mechanical properties of the WPC. The ability of the atomic force microscope (AFM) to create 3D images of topography and various interaction forces with molecular resolution made it a valuable tool for the analysis of adhesion properties in WPCs.

“…The second is atomic force spectroscopy (AFS), one of the most promising and interesting research areas related to SPM, allowing the study of surface interactions between a tip and sample surface from a theoretical point of view by means of forcedistance curves, measuring forces as a function of distance. These curves can be employed for the study and measurement of numerous materials properties such as elasticity, Hamaker constant, surface charge densities and degrees of hydrophobicity and also for the characterization of all the known kinds of surface forces 3 .…”

Nanocomposite fiber materials, particularly those constructed with uniform reinforcements, have been sought for a long time in materials science. The hoped-for enhancement of the properties of polymer-nanofiber composites have remained elusive, owing in part to the difficulties in performing mechanical measurements. Harnessing the strength of atomic force spectroscopy therefore offers a new handle for the measurement of mechanical properties such as elastic modulus. The paper, here, addresses distance dependent measurements (DDM) performed on the multi-walled carbon nanofiber (CNF) reinforced composite fibers. To quantitatively measure the elastic modulus of nanocomposite materials, measurements were carried out on different points on the surface of the sample and ForceDistance curves were then plotted. The obtained results fairly agree to previously measured values. The great improvement in elastic modulus was achieved without sacrificing the mechanical strength and stiffness of the polymer, and with minimal weight penalty. † Corresponding author: Pirooz Marashi, Tel: +98 (21)
