“…The hydrophobic characteristics of nanocomposite were outlined by measuring the contact angle of the sessile drop based on the apprehension developed by Balasubramanian et al . They have extensively explored the contact angle of various surfaces which predominantly depends on the surface roughness, surface energy and surface tension based on the proposed model of Cassie and Baxter 51 52 53 . In this context, we have contemplated hydrophobic attribute of developed polymer nano composite based on alteration in surface energy by the amalgamation of POSS units in PC matrix.…”

Inorganic/organic nanofillers have been extensively exploited to impart thermal stability to polymer nanocomposite via various strategies that can endure structural changes when exposed a wide range of thermal environment during their application. In this abstraction, we have utilized temperature assisted in-situ small angle X-ray scattering (SAXS) to examine the structural orientation distribution of inorganic/organic nanofiller octa phenyl substituted polyhedral oligomeric silsesquioxane (Ph-POSS) in Polycarbonate (PC) matrix from ambient temperature to 180 °C. A constant interval of 30 °C with the heating rate of 3 °C/min was utilized to guise the temperature below and above the glass transition temperature of PC followed by thermal gravimetric, HRTEM, FESEM and hydrophobic analysis at ambient temperature. The HRTEM images of Ph-POSS nano unit demonstrated hyperrectangular structure, while FESEM image of the developed nano composite rendered separated phase containing flocculated and overlapped stacking of POSS units in the PC matrix. The phase separation in polymer nanocomposite was further substantiated by thermodynamic interaction parameter (χ) and mixing energy (Emix) gleaned via Accelrys Materials studio. The SAXS spectra has demonstrated duplex peak at higher scattering vector region, postulated as a primary and secondary segregated POSS domain and followed by abundance of secondary peak with temperature augmentation.

“…2, when it came into contact with oil dispersed on the surface of water, the composite surface immediately absorbed the oil layer around it, giving rise to the emergence of a transparent water surface. 8,[22][23][24][25] At the same time the oil gradually shrunk and completely disappeared in a few minutes, which illustrates superoleophilicity of the composite. The absorption capacities of the composites for different oils and solvents could be controlled by the existence of the hierarchical porous network structure, and the density and viscosity of the oils and organic solvents.…”

“…Most of the applications require coatings for large surfaces. In recent years, the focus has shifted towards industrial applications and multi-functionality in the fabricated surfaces (including reflection and transparency switchability) [52,53]. However, many strategies to hydrophobize surfaces are not easily applicable to large surface areas [54].…”

Since the discovery of the self-cleaning properties of the lotus effect, the wetting of surfaces were intensively investigated due to their potential application in many industrial sectors. The transparency of flexible liquid repellent coatings are a major industrial problem and their economic consequences are widely known. Hence, a comprehensive understanding of the developments of flexible and transparent superamphiphobic surfaces is required in a number of technological and industrial situations. In this review, we aim to discuss the progress in the design, synthesis, fabrication techniques, and applications of flexible and transparent superamphiphobic surfaces. We start with an introduction, exploring the contact angles and wetting states for superhydrophilic, superhydrophobic, and superoleophobic surfaces, and continue with a review of the wetting transition of such surfaces. Then, we highlight the fabrication techniques involved for the preparation of flexible and transparent superamphiphobic surfaces. This review also discusses the key issues in the fabrication process and surfaces, and their features in improving durability characteristics and self-repellent performance. Then we suggest various recommendations for the improvement of mechanical durability along with potential future directions towards more systematic methods that will also be acceptable for industry. Finally, we conclude with some challenges and potential applications.
