Electrospinning of poly(ethylene oxide)/glass hybrid nanofibers for anticounterfeiting encoding

Abstract

Abstract The use of photochromism to increase the credibility of consumer goods has shown great promise. In order to provide mechanically dependable anticounterfeiting nanofibers, it has also been critical to improve the engineering processes of authentication patterns. Mechanically robust and photoluminescent electrospun poly(ethylene oxide)/glass (PGLS) nanofibers (150-350 nm) integrated with nanoparticles of lanthanide-doped aluminate (NLA; 8-15 nm) were developed using electrospinning technology for anti-counterfeiting purposes. The provided nanofibrous films change color from transparent to green when illuminated with ultraviolet light. By delivering NLA with homogeneous distribution without aggregations, we were able to keep the nanofibrous film transparent. When excited at 365 nm, the NLA@PGLS nanofibers displayed emission intensity at 517 nm. The hydrophobicity of NLA@PGLS nanofibers was improved by raising the pigment concentration. After being triggered by ultraviolet light, NLA@PGLS showed quick and reversible photochromism without fatigue. It has been shown that the suggested method can be applied to reliably produce a variety of anti-counterfeiting materials.
