“…It is also worthwhile to note that the range of applications of PVC—already quite large—is still increasing. Thus, Chapman and his colleagues created hydrophobic PVC. Such a material can be used for antifouling in marine environments.…”

Poly(vinyl chloride) (PVC) is widely used—in spite of HCl formed from it at elevated temperatures. PVC wire and cable insulation has poor thermal stability, causing the plasticizer to separate from the PVC chains and produce an oily residue, lowering the tensile elongation at break and thus increasing brittleness. One uses cross‐linking agents and antioxidants, as well as mixtures of both, to improve the thermal stability of the plasticizer and tensile properties of PVC after thermal exposure. We performed tensile tests, tribological tests, profilometry, scanning electron microscopy (SEM), and water absorption determination before and after thermal exposure at 136 °C for 1 week. After adding the agents, elongation at break increased by 10 to 20% while the wear rate and water absorption were lower than for the control sample. Less voids are seen in the SEM images after adding these two kinds of agents. The thermal resistance of the PVC cable insulation is best enhanced by combinations of cross‐linking agents and antioxidants. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48816.

“…[6,7] Moreover superhydrophobic surfaces have shown efficient response in various applications including self-cleaning, bio-fouling control, and corrosion protection in addition to oil-water separation due to their water-repellent characteristics. [8][9][10][11][12][13] Literature provides a good understanding of superhydrophobic phenomenon as mimicked by creating rough micrometer and nanometer scale hierarchical structures with low surface energy. [14][15][16]25,26] Hence, a variety of nanomaterials are used to generate hierarchical surface roughness necessary for superhydrophobic properties; some of these include nanodiamonds, silica, iron oxide, titania, alumina, carbon soot, and carbon nanotubes.…”

Durable and Recyclable Superhydrophobic Fabric and Mesh for Oil–Water Separation

et al. 2017

The authors report durable and recyclable nanocomposite superhydrophobic coatings on two different substrates of fabric and mesh as prepared by titania nanoparticles and polydimethysiloxane (PDMS). The felted wool fabric and the steel mesh are initially coated with a thin layer of PDMS, which is followed by the deposition of nanocomposite coating of titania nanoparticles embedded in PDMS. The dual surface modification of two kinds of substrates generates highly hydrophobic surface character, which is retained after durability performance as measured in ultrasonication, sand, and emery paper abrasion tests. Oil-water separation experiments are performed using water mixtures with four oils, that is, n-hexane, toluene, kerosene, and diesel to ensure the industrial applications of prepared composite materials.Moreover, nanocomposite coatings are tested for several cycles of oil-water separation in harsh conditions such as hot water, sodium chloride, and hydrochloric acid. The adopted approach improves the separation performance by inducing durability of the prepared nanocomposite coatings along with introducing recyclable character.

A Self‐Cleaning Mucus‐like and Hierarchical Ciliary Bionic Surface for Marine Antifouling

et al. 2020

The flexible mucus film and hydrophilic hierarchical micro‐/nanoprotuberance structure on the skin surfaces of marine organisms contribute to an excellent intrinsic antifouling performance. Inspired by this fact, a self‐cleaning mucus‐like and hierarchical ciliary bionic antifouling surface (SMCAS) is designed for marine antifouling based on the electrostatic flocking technology. The results of scanning electron microscopy (SEM) show that the bioinspired SMCAS has a hierarchical micro‐/nanociliary structure and the micrometer array of polyamide (PA) microfibers is covered with the nanometer carbon nanotube/polyvinyl alcohol (CNT/PVA) hydrogel particles. The biomasses of the two marine microoganisms, Nitzschia closterium f. minutissima and Marinobacter lipolyticus SM19 (T), attached on the SMCAS are investigated using a UV–visible spectrophotometer (UV–vis) and SEM. The results reveal that the microoganisms attached on the SMCAS are significantly lower number in comparison with the organic silicon coating. In addition, the SMCAS has a greater ability of stain removal in the dyed petroleum ether washing test. Therefore, the SMCAS demonstrates an extraordinary antifouling performance due to the synergetic effect of the mucus‐like hydrogel film and the hierarchical micro‐/nanostructured micropillars.
