“…The use of nanostructured coatings takes advantage of the precise control of their thickness at a nanometer scale. According to Bratek-Skicki [ 9 ], the rapidly-growing field of nanostructured stimuli-responsive coatings resulted in many advances in developing multi-functional systems. The coating responses can be color changes, energy release, shape adaption, drug release, changes in the dimensional structure of the textile fibers, and many others thus providing a wide panorama of wearable sensors as a consequence of their integration with textile structures.…”

This review presents current literature on different nanocomposite coatings and surface finishing for textiles, and in particular this study has focused on smart materials, drug-delivery systems, industrial, antifouling and nano/ultrafiltration membrane coatings. Each of these nanostructured coatings shows interesting properties for different fields of application. In this review, particular attention is paid to the synthesis and the consequent physico-chemical characteristics of each coating and, therefore, to the different parameters that influence the substrate deposition process. Several techniques used in the characterization of these surface finishing coatings were also described. In this review the sol–gel method for preparing stimuli-responsive coatings as smart sensor materials is described; polymers and nanoparticles sensitive to pH, temperature, phase, light and biomolecules are also treated; nanomaterials based on phosphorus, borates, hydroxy carbonates and silicones are used and described as flame-retardant coatings; organic/inorganic hybrid sol–gel coatings for industrial applications are illustrated; carbon nanotubes, metallic oxides and polymers are employed for nano/ultrafiltration membranes and antifouling coatings. Research institutes and industries have collaborated in the advancement of nanotechnology by optimizing conversion processes of conventional materials into coatings with new functionalities for intelligent applications.

“…Developing materials from renewable sources with a high strength-to-weight ratio such that the flexural performance of the material is high in respect to its weight remains a challenging task for engineers and scientists (Parashar et al, 2021;Okokpujie et al, 2020;Jiang et al, 2020;Bratek-Skicki, 2021;Tu et a., 2021;Reddy et al, 2020). Natural fibers from plant materials have in recent times been exploited for applications in several industries due to their low density and environmental friendliness.…”

With the continuous need for sustainable, environmentally friendly, and low-cost systems, processes, and materials, natural fibers have been a major topic of discussion in the materials science community as it has increasingly found acceptance in material development as an alternative to synthetic fibers due to environmental concerns. Although many studies have been carried out in this regard, the optimal flexural performance of pineapple leaf fiber/synthetic fiber hybrid reinforced composite has not been studied even with its promising application in aviation, health, and fitness, marine, etc. In this study, a Pineapple Leaf fiber (PALF)/Glass fiber Epoxy hybrid composite PxGyEz (with x, y, and z representing the volume fraction of pineapple leaf fiber, the volume fraction of glass fiber, and fiber length respectively) was developed and its flexural properties optimized and modeled with regards to the variable manufacturing parameters of x, y, and z respectively. For the quality characteristics (flexural strength) investigated, the Minitab®19 software was used to analyze the Taguchi robust experiment design technique on a higher the better basis. The optimum combination of the control factors was found at x = 20%, y = 20%, and z = 25mm. The optimized composite P20G20E25 possessed a flexural strength of 144.4994MPa which was only a 7.17% deviation from the predicted optimum flexural strength. Analysis of variance showed that the PALF had the highest contribution of 23.97% to the flexural strength of the PxGyEz, glass fiber 7.13%, and fiber length 12.79%. SEM Images of the PALF, glass fiber, and the fractured surface of the optimized material P20G20E25 revealed the surface structure which explained their different contribution to the flexural strength of the materials. An equation for the prediction of the flexural properties of PxGyEz was derived from the regression model and it had an approximately 77.57% agreement with experimentation.

“…The latter may be characterized by lower stability of the textural characteristics than stable and rigid solids due to various effects of dispersion media, swelling, aging, freezing with liquids, heating, mechanical loading, as well as due to high fractality, strongly tortuous pores, and disordered texture of nonrigid polymers [26][27][28][29][30][31][32][33][34]. Various composites [35][36][37][38], nanostructured polymers [39][40][41][42][43][44][45], polymer/oxides [46][47][48], and polymer/carbons [49][50][51][52] composites are of interest from a practical point of view. However, accurate textural characterization of polymeric composites, complex filler-polymer and filler-polymer-polymer systems is a more difficult task than a similar challenge for individual oxide, carbon, or polymeric materials.…”

Various methods for morphological, textural, and structural characterization of polymeric, carbon, and oxide adsorbents have been developed and well described. However, there are ways to improve the quantitative information extraction from experimental data for describing complex sorbents and polymer fillers. This could be based not only on probe adsorption and electron microscopies (TEM, SEM) but also on small-angle X-ray scattering (SAXS), cryoporometry, relaxometry, thermoporometry, quasi-elastic light scattering, Raman and infrared spectroscopies, and other methods. To effectively extract information on complex materials, it is important to use appropriate methods to treat the data with adequate physicomathematical models that accurately describe the dependences of these data on pressure, concentration, temperature, and other parameters, and effective computational programs. It is shown that maximum accurate characterization of complex materials is possible if several complemented methods are used in parallel, e.g., adsorption and SAXS with self-consistent regularization procedures (giving pore size (PSD), pore wall thickness (PWTD) or chord length (CLD), and particle size (PaSD) distribution functions, the specific surface area of open and closed pores, etc.), TEM/SEM images with quantitative treatments (giving the PaSD, PSD, and PWTD functions), as well as cryo- and thermoporometry, relaxometry, X-ray diffraction, infrared and Raman spectroscopies (giving information on the behavior of the materials under different conditions).
