Nano-and micro-sized devices have great potential for practical use in chemistry, physics, biology, materials science, and medicine. The basis of nano-and Microtechnologies is a class of devices known as nanoelectromechanical systems (NEMS) or microelectromechanical systems (MEMS). With the development of technologies, the production of polymer microstructures, in particular, based on polyvinylidene fluoride (PVDF), becomes more promising compared to traditional materials. PVDF is a thermoplastic fluorinated polymer and is characterized by high chemical resistance over a wide temperature range.
In this article, polytechnics summarized the latest achievements in the use of anodized aluminum oxide (AAO) membranes as templates for producing piezoelectric nano-or microgenerators based on PVDF or polyvinylidene fluoride-trifluoroethylene (PVDF-Trfe). These materials are used in biomedical applications, devices for generating renewable energy as a result of human daily activity, as well as for the manufacture of sensors.
The characteristics of the resulting devices for energy storage and other applications can be significantly improved when using nano - and microstructured piezopolymer surfaces compared to conventional films of the same material. Mechanisms for improving the electrophysical properties of PVDF and its copolymers in nano-and micro-scales are also described in the article.
The results are published in two review papers in the journals Nano Energy (Q1, IF: 16.6; CiteScore 23.1) and Ceramics International (Q1, IF: 3.83; CiteScore 6.1).
