“…Therefore, the mechanical toughness and adhesion ability of electrode film composed of NFs are greatly limited. Inspired by spider webs with dewdrops, by spraying PDMS on the fiber surface and wrapping flexible PDMS microdroplets at the fiber nodules, the mechanical strength can be effectively improved to maintain the web structure of NFs [105]. At the same time, due to the excellent adhesive qualities of PDMS, its adhesion to various substrates can be improved.…”

Flexible and stretchable transparent electrodes are widely used in smart display, energy, wearable devices and other fields. Due to the limitations of flexibility and stretchability of indium tin oxide (ITO) electrodes, alternative electrodes have appeared, such as metal films, metal nanowires, and conductive meshes. However, few of the above electrodes can simultaneously have excellent flexibility, stretchability, and optoelectronic properties. Nanofiber (NF), a continuous ultra-long one-dimensional conductive material, is one of the most promising materials for high-performance transparent electrodes with excellent properties due to its unique structure. This paper summarizes the important research progress of NF flexible transparent electrodes (FTEs) in recent years from the aspects of NF electrode materials, preparation technology and application. First, the unique advantages and limitations of various NF materials are systematically discussed. Then, we summarized the preparation technology of various advanced NF FTEs, and pointed out the future development trend. We also discussed the application of NFs in solar cells, supercapacitors, electric heating equipment, sensors, etc., and analyzed its development potential in flexible electronic equipment, as well as problems that need to be solved. Finally, the challenges and future development trends are proposed for the wide application of NF FTEs in the field of flexible optoelectronics.

In the context of environmental protection and energy conservation, it is of great practical significance to study the design of porous material energy absorbing structures on the ground of spider web biomimetic structures. This study designs a porous material energy absorbing structure on the ground of a biomimetic spider web structure. Through in-depth research and experiments, the characteristics of this structure in efficient energy absorption are demonstrated. It has three types of energy absorbing structures: simple design, spiral and composite. The experimental data showed that the simple structure exhibited an energy absorption of 50 mJ under a 5J impact force, with an energy absorption efficiency of 10 mJ/g. At a 20J impact force, the energy absorption reached 200 mJ and the energy absorption efficiency was 40 mJ/g. Under parameter optimization, the cross-sectional diameter of the spiral and the cross-sectional area of the radial significantly affected the energy absorption effect. Reducing the cross-sectional diameter of the spiral from 0.55 mm to 0.45 mm would result in a decrease in energy absorption from 1.775J to 1.59J. When the cross-sectional area of the radial line changed from 0.5 to 0.45, the energy absorption effect decreased from 1.775J to 1.644J. Under static load, the composite structure had a 700 N triggering force and lower peak stress compared to the spiral structure under a compression displacement of 10 mm without compaction. The comprehensive performance of the composite structure is superior. This study provides a reference for designing more efficient and reliable energy absorbing materials, and the results have theoretical significance and practical application value. On the ground of experimental data and conclusions, biomimetic spider web structures can achieve safe, efficient, and reliable energy absorption protection in modern industrial applications, providing important theoretical support and technical guidance. The study of the energy absorption structure of porous materials based on spider web biosimulation has important theoretical and practical value in improving the safety, efficiency, and reliability of modern industrial applications. It provides a new direction and strategy for the development and application of high-performance energy absorption materials.

“…In a previous study, we reported a transparent electrode film with improved electrical properties and mechanical strength by generating PDMS droplets on metal nanofibers using a spray method. 23 However, the PDMS micro droplets partially covered the metal nanofibers, so the surface of the conductive nanofibers was not completely exposed. In this study, we developed a fabrication process for Conductive nanofiber web film with PDMS side wall selectively coated through the reactive ion etching (RIE) process for highperformance flexible transparent electrodes.…”

“…Because the PDMS and nanofiber were attached, the mechanical strength was excellent; however, it could only be applied to the PDMS substrate and had a high film thickness. In a previous study, we reported a transparent electrode film with improved electrical properties and mechanical strength by generating PDMS droplets on metal nanofibers using a spray method . However, the PDMS micro droplets partially covered the metal nanofibers, so the surface of the conductive nanofibers was not completely exposed.…”
