“…For icephobic coatings on solar energy harvesting systems, windows and curtain walls, transparency has critical importance [15]. If the layer is not sufficiently optical transparent, some of the sunlight would be difficult to reach the solar systems which significantly affects the efficiency of the solar cells.…”

Icephobic surfaces have attracted increasing attention due to their wide ranging application areas from wind and solar energy systems to aviation. Slippery liquid-infused porous surfaces (SLIPS) are being explored for passive ice protection due to their lower ice adhesion strength.In this study, we present a cost-effective and scalable electrospinning technique to produce freestanding nanofibrous polymeric surfaces for the fabrication of transparent icephobic SLIPS. The diameter of the electrospun fibres produced varied from 200 to 400 nm and the membranes had a theoretical porosity of 71.6 ±4.1%. Furthermore, three different lubricants polychlorotrifluoroethylene oil (PcTFE), silicone oil and liquid paraffin, were used and it was observed that when silicone oil and PcTFE were used as lubricants for SLIPS, they provided high optical transparency (>90%) in the visible light spectrum compared to PVDF-co-HFP itself. All SLIPS were subjected to centrifugal ice adhesion testing which revealed their ice adhesion strengths lower than 1 KPa with significant delay in droplet icing compared to aluminium reference, from 5 up to 41 sec. The results indicated that enhanced icephobic properties of electrospun membranes have been clearly demonstrated.

“…The whole set was flipped upside down and placed inside a climate chamber (Cincinnati Sub-Zero environmental chambers, U.S.A.) for 24 h at −15 °C and −20 °C. The weight of infilled water was 1.5 g. Measurements of the ice-adhesion strength followed a previous report [2,39]. The reported ice-adhesion strength was an average value of at least six measurements on the same position of each sample, and a total of at least three samples of the same condition.…”

“…Extensive experiments were conducted to investigate the influence of these two factors on anti-icing performance. It is clear that lower surface energy of a surface results in lower ice adhesion [36][37][38][39] and lower icing probability [40,41]. However, roughness as a key characteristic of a surface could not reflect all the surface properties, especially for rough porous surfaces.…”

Among different types of anti-icing coatings, superhydrophobic coatings have attracted considerable attention due to their water repellency and low heat-transfer rate. However, condensation on superhydrophobic surfaces at low temperatures usually causes an increase in ice adhesion because of the induced wetting of micro-and nanostructures. By tuning the weight ratio of surface-modified nanoparticles to unmodified ones, five superhydrophobic coatings with different structural features at the microscale were developed. Ice-adhesion strength and ice-nucleation temperature were studied, together with the effect of moisture condensation on ice adhesion. It was found that the ice-adhesion strength and icing temperature of these coatings do not necessarily follow the same order among these surfaces because of different mechanisms involved. Surface roughness is inadequate to describe the necessary surface features that critically affect the anti-icing behavior of the coatings. Detailed topology/geometry has to be considered when designing icephobic coatings. Superhydrophobic coatings can be adopted for icephobic applications once the surface topology is carefully designed.

“…Different from metal and ceramic materials, the transparency of polymer materials mainly depends on its crystallinity [ 40 ]. The polymers with high crystallinity will increase light reflection, resulting in high light loss and low light transmittance.…”

The optically transparent electrospun fibrous membrane has been widely used in many fields due to its simple operation, flexible design, controllable structure, high specific surface area, high porosity, and unique excellent optical properties. This paper comprehensively summarizes the preparation methods and applications of an electrospun optically transparent fibrous membrane in view of the selection of raw materials and structure modulation during preparation. We start by the factors that affect transmittance among different materials and explain the light transmission mechanism of the fibrous membrane. This paper also provides an overview of the methods to fabricate a transparent nanofibrous membrane based on the electrospinning technology including direct electrospinning, solution treatment after electrospinning, heat treatment after electrospinning, and surface modification after electrospinning. It further summarizes the differences in the processes and mechanisms between different transparent fibrous membranes prepared by different methods. Additionally, we study the utilization of transparent as-spun membranes as flexible functional materials, namely alcohol dipstick, air purification, self-cleaning materials, biomedicine, sensors, energy and optoelectronics, oil–water separation, food packaging, anti-icing coating, and anti-corrosion materials. It demonstrates the high transparency of the nanofibers’ effects on the applications as well as upgrades the product performance.
