Special Issue Information

In recent years, the integration of stimuli-responsive materials and their intrinsic mechanisms with functional coatings has become a common practice in order to make smart surfaces capable of responding under specific conditions for numerous protective applications. This variety of smart surfaces with self-cleaning, self-healing, self-lubricating, heat-responsive, and light-sensitive properties have advanced applications in the field of anticorrosion, fire-retardant, antifouling, wear-resistant, and smart glazing technologies. The market value of smart coatings was USD 1.75 billion in 2016, and is predicted to reach USD 6.27 billion by 2022, at a CAGR of 23.87% (according to global market research). Being an emerging field, excellent research progress has been made in recent years. Nevertheless, there are significant challenges to overcome, such as in achieving adequate scalability, cost, and mechanical and thermal stability of these coatings before they are considered to be suitable for commercialization. Other challenges remain in the design and fabrication of smart additives and their compatibility with the coating matrix. In the long run, it is very likely that the use of new smart nanomaterials and polymers will play a significant role in the development of future smart coating technologies.

The purpose of this Special Issue is to collect state-of-the-art works on multifunctional smart coatings in protective coating applications. In addition to original research works, comprehensive reviews and feature articles highlighting recent advances in the field of emerging smart coatings are most welcome. Therefore, it is my great pleasure as Guest Editor to invite you to submit contributions to this Special Issue.

A large background scattering originating from the sample matrix is a major obstacle for fine-structure analysis of a nanometric layer buried in a bulk material. As polarization analysis can decrease undesired scattering in a neutron reflectivity (NR) profile, we performed NR experiments with polarization analysis on a polypropylene (PP)/perhydropolysilazane-derived SiO2 (PDS)/Si substrate sample, having a deep-buried layer of SiO2 to elucidate the fine structure of the nano-PDS layer. This method offers unique possibilities for increasing the amplitude of the Kiessig fringes in the higher scattering vector (Qz) region of the NR profiles in the sample by decreasing the undesired background scattering. Fitting and Fourier transform analysis results of the NR data indicated that the synthesized PDS layer remained between the PP plate and Si substrate with a thickness of approximately 109 Å. Furthermore, the scattering length density of the PDS layer, obtained from the background subtracted data appeared to be more accurate than that obtained from the raw data. Although the density of the PDS layer was lower than that of natural SiO2, the PDS thin layer had adequate mechanical strength to maintain a uniform PDS layer in the depth-direction under the deep-buried condition.

In this work, the electrospinning technique is used for the fabrication of electrospun functional fibers with desired properties in order to show a superhydrophobic behavior. With the aim to obtain a coating with the best properties, a design of experiments (DoE) has been performed by controlling several inputs operating parameters, such as applied voltage, flow rate, and precursor polymeric concentration. In this work, the reference substrate to be coated is the aluminum alloy (60661T6), whereas the polymeric precursor is the polyvinyl chloride (PVC) which presents an intrinsic hydrophobic nature. Finally, in order to evaluate the coating morphology for the better performance, the following parameters—such as fiber diameter, surface roughness (Ra, Rq), optical properties, corrosion behavior, and wettability—have been deeply analyzed. To sum up, this is the first time that DoE has been used for the optimization of superhydrophobic or anticorrosive surfaces by using PVC precursor for the prediction of an adequate surface morphology as a function of the input operational parameters derived from electrospinning process with the aim to validate better performance.
