- Аннотация: Charge storing concepts receive an increasing interest in a view of the fast development of flexible textile electronics. The paper reports on initial charging capacity and charge conservation properties of technical textiles modified with UV-cured organic thin films. The results have been evaluated for three types of textile substrates and two types of monomers, an acrylic and allylic, with differing UV-absorption spectral characteristics. The most pronounced increase of the decay time from a few minutes to several hours has been found for polyethylene terephthalate (PET) fibers coated with thin layers of UV-cured tetraallyloxyethane monomer, representing ca 1 wt-% add-on. The mechanisms behind the measured effects could be rationalized along the concepts of “grafting to” and “grafting from” polymerization, which defines the tethering density, layer thickness and the degree of cross-linking. The behavior proved to be stable both under normal conditions and under elevated temperature/humidity conditions. The reported results provide design strategies for thin organic coatings with regards to targeted applications.Highlights•UV-cured organic thin layers improve charge storage performance of textile nonwovens.•Initial charging of modified PET nonwovens increases by an average factor of 3.•poly-TAE modified samples exhibit a significant increase in charge storage.•Charge decay times up to 4 h are attained compared to < 3 min untreated.•Governing factor is the degree of cross-linking, which affects monomer mobility.
