Layer-by-layer self-assembled porous crustacean-nanofiber structure.

Scientists studied the growth of porous crustacean-nanofiber structures in anti-reflective and anti-fog coatings under existing ions.
anti-reflective surface reduces reflectivity and maximizes light transmission.

. Therefore, these types of surfaces play an important role in optical technology. The development of anti-reflective surfaces is accelerated by precise control of coating thickness and refractive index from nanoscale to micron scale. A promising technique for the production of anti-reflective coatings is the layer-by-layer (LbL) method, which has recently been significantly improved, particularly in the use of fiber materials.
anti-reflective nanogenic fiber coating
however, nanofiber LbL membranes are still difficult to manufacture because ion effects hinder self-assembly and deteriorate porous nanofiber structures. To solve this problem, a new study has created an anti-reflective nanogen fiber coating by controlling the porosity rates under various ion conditions in the LbL method. The addition of NaCl changes the ion condition and the composition of the polymer, thus increasing the porosity of the membrane, which consists of cational butyl nanofibers and anion polyacrylic acid.
transmission rate of the resulting structure at 550nm was 93.7% and the refractive index was 1.30. The coating reduces fog due to the hydroelectural surface of the crustacean nanofibers and the strong hydrogen bonding.
the study was published in May 2020 in volume 142 of Organic Coatings Progress.
