“…Gnanou and Fontanille [31] stated that three interaction types are responsible for the cohesion in polymers: van der Waals interactions (Keesom forces, Debye forces and London forces), hydrogen bonds and ionic bonds. In polymer composites the interaction between the polymer and the filler is developed during processing in the melt state and is a combination of van der Waals (VDW) interactions, specific chemical interactions and chemical bonds between the polymer and the filler surface [25]. In their study, Chau et al [17] stated that the adhesion force between two surfaces physically originates from van der Waals forces, electrostatic forces, intermolecular forces, Casimir forces or meniscus forces depending on physical and/or chemical properties of those surfaces.…”

“…These forces depend strongly on the interaction medium (air, water, vacuum) and the four fundamental contributions due to VDW forces, capillary forces, electrostatic forces for charged surfaces and static forces [72]. In polymer composites, the interaction between the polymer and the filler is developed during processing in the melt state and is a combination of VDW interactions, specific chemical interactions and chemical bonds between the polymer and the filler surface [25]. In general, the adhesion force between an AFM tip and a sample surface In AFM pull-off measurements, continuum contact mechanics models are commonly used to describe the probe/substrate system [85].…”

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.

“…[2,3] Attempts to understand the modifications in the tribological behavior of the polymers with the addition of filler or fiber reinforcements have been made by many researchers. [4,5] Many investigations have shown that the incorporation of fiber reinforcement improved the wear resistance and reduced the coefficient of friction, provided good interfacial adhesion between the matrix and the fiber reinforcement existed.…”

Polyacrylamideacrylate (PAN)-based carbon fibers were submitted to nitric acid oxidation treatments to improve the interfacial adhesion of the carbon fiber (CF)-reinforced polyimide (CF/PI) composite. The carbon fiber surfaces were characterized by X-ray photoelectron spectroscopy (XPS). Nitric acid oxidation not only affects the oxygen concentration but also produces an appreciable change in the nature of the chemical functions, namely the conversion of hydroxy-type oxygen into carboxyl functions. Nitric acid oxidation treatment modifies the element constituting the fiber, the nitrogen concentration being about 1.2 times higher at the fiber external surface compared to the untreated one. The mechanical and tribological properties of the polymide (PI) composites reinforced by the carbon fibers treated with nitric acid oxidation were investigated. Results showed that the tensile strength of the CF/PI composites improved remarkably due to nitric acid treatment along with enhancement in friction and wear performance.
