“…The number of contact points on a surface plays a crucial role in determining the quality of contact between two objects. This parameter reflects the number of reliefs or asperities present on the surface, such as roughness, furrows, or grooves, which contribute to its overall surface structure [44]. When two surfaces come into contact, it is not only the total contact area that matters, but also the quality of that contact.…”

Ceramics-polymer composites have garnered significant interest in recent years due to their unique combination of properties and potential applications. This study presents an in-depth analysis of the surface and wettability properties of new Na2Ti3O7/Na2Ti6O13/PVA composite, aiming to uncover their unique characteristics. The analysis revealed notable changes in the morphology and 3D spatial patterns of the films upon incorporating heated and unheated Na2Ti3O7/Na2Ti6O13 into the PVA matrix. The PVA film containing heated ceramics displayed hierarchical topographic roughness (3.71±1.13 nm) similar to those of pure PVA films (2.28±0.13 nm), contrasting with the film containing unheated ceramics (12.31±2 nm). The surface texture of all films exhibited comparable isotropies (without significant difference at a p-value=0.05), indicating that their physical properties remained largely unaffected by the heat treatment imposed on the ceramics. The surface microtexture similarity between the PVA film and the one containing heated ceramics can be attributed to their comparable spatial complexity (FD=2.41‒2.44). Contact angle measurements further demonstrated similar surface wettability between pure PVA (54.5±1.4°) and PVA containing heated Na2Ti3O7/Na2Ti6O13 ceramics (58.6±2.6°), which can be attributed to the resemblances in their surface microtextures. These findings highlight the pivotal role of heat treatment in the formation of Na2Ti3O7/Na2Ti6O13/PVA composites with surface and wettability properties akin to those of pure PVA films. This research contributes to the understanding of composite materials and their potential for various applications, including anticorrosive coatings, sensor devices, and surface engineering.

“…The study and design of structured surfaces represents a new frontier for science, because unlike surfaces produced by conventional methods, they have specific functional performances [1,2], such as hydrophobic or hydrophilic [3,4], anti-corrosive [5,6], anti-icing [7,8,9], and osseointegration [10,11] properties, to name a few. As indicated by Wong et al and MacAulay et al [12,13], it is essential to develop efficient, high precision surface characterization methods for structured surfaces.…”

This work describes a method for the metrological characterization of structured surfaces using a confocal microscope. The proposed method is based on the calculation of texture parameters established in ISO 25178-2:2012. To ensure the traceability of these parameters, a procedure for the calibration of the Z-axis of the confocal microscope is proposed. The calculation of uncertainty associated with each parameter employs the Monte Carlo method, as well as the concept of a virtual instrument. The validity of the algorithms has been verified through the use of synthetic data provided by the National Institute of Standards and Technology (NIST) and physical standards, with minimum differences being obtained between the certified values and calculated or measured values. Finally, using the proposed method, the topography of a structured surface manufactured by laser machining is evaluated, obtaining the most used roughness parameters, as well as their measurement uncertainties and possible correlations. In general, it can be affirmed that it is possible to obtain metrologically reliable results with the proposed method.
