The hydrophobic silica nanoparticles have been widely used in the fabrication of superhydrophobic surfaces. In this study, we prepared superhydrophobic coating using hydrophobic SiO2 nanoparticles by facile dip coat technique. After that, a layer of cyanoacrylate adhesive was applied to improve the durability of the superhydrophobic coating. Finally, the coating was annealed at 200 °C for 10 min. A water drop on prepared superhydrophobic coating showed contact angle ≈173° and sliding angle ≈1°. The prepared superhydrophobic coating revealed self‐cleaning behavior for more than 2 years. This approach can be useful for fabrication of superhydrophobic coating for practical industrial application including solar panel, windows glass, vehicle glass and fabrics, and so on.

“…A superhydrophilic surface is generally defined as exhibiting a water contact angle (WCA) of less than 5° and a superhydrophobic surface is one in which the WCA is greater than 150°. Superhydrophilic surfaces have been investigated for their potential to provide antifogging, self‐cleaning and antifouling devices, and oil/water separation while superhydrophobic surfaces have been prepared due to their potential applications such as self‐cleaning, anti‐icing, and anti‐corrosion …”

In this study, the authors researched the preparations of superhydrophilic/superhydrophobic surfaces on commercial cup stock polyethylene coated papers by using sparked aluminum nanoparticles deposited on substrates through a sparking process. In this stage, the surface was porous and showed superhydrophilic properties. The samples were then annealed in air at various temperatures and some transformed to superhydrophobicity. It is well known that a suitable roughness in combination with low surface energy has been required to obtain superhydrophobic surfaces. Therefore, it is believed that during annealing process, when polyethylene is diffused from the substrate through the nanoparticle films and the superhydrophobic characteristics were created. The scanning electron microscope images showed that the film surfaces had a fluffy structure for both the as‐deposited and the annealed samples. However, the atomic force microscopy phase images showed completely different surface properties. Moreover, the X‐ray photoelectron spectroscopy spectra showed different surface chemical compositions. The experimental results revealed that the working temperature to produce superhydrophobic surfaces depended on the sparked film thickness. Furthermore, in order to prove the assumption explained above, glass and poly (methyl methacrylate) were also used as substrates.

Self-cleaning effects of superhydrophobic surface are promoted by the large contact angle and small hysteresis (Liu et al 2015c) and governed by threephase contact lines of the drop-in planes of liquid-gas interface, solid-gas interface and solid-liquid interface.…”

“…Similarly, the PET film coated by titania-silica nanocomposite realized increase in hydrophobicity and decrease of the water contact angle in the modified films surface from 82.7°to 18.7° Wu et al 2015a). Liu et al (2015b) developed the self-cleaning surface of glass substrate, (Heptadecafluoro-1,1,2,2-tetrahydrodecyl)trimethoxysilane and exhibited superhydrophobicity features with rough surface, hill-like morphological surface and wrinkled surface resembling the microstructural features of lotus leaf. The contact angle of the glass surface increased to 169°with tilt angle lower than 5°.…”

In recent decades, there is a global advancement in manufacturing industry due to increased applications of nanotechnology. Food industry also has been tremendously changing from passive packaging to innovative packaging, to cope with global trends, technological advancements, and consumer preferences. Active research is taking place in food industry and other scientific fields to develop innovative packages including smart, intelligent and active food packaging for more effective and efficient packaging materials with balanced environmental issues. However, in food industry the features behind smart packaging are narrowly defined to be distinguished from intelligent packaging as in other scientific fields, where smart materials are under critical investigations. This review presents some scientific concepts and features pertaining innovative food packaging. The review opens new research window in innovative food packaging to cover the existing disparities for further precise research and development of food packaging industry.
