Examination of Biopolymer Electrodeposition with Functional Additives

Abstract

Here we describe how electrodeposition of biopolymers can be used to prepare coatings incorporating additives to control interactions within the RF regime of the electromagnetic spectrum. Specifically, pH changes are used to drive the co-deposition of two polysaccharides (chitosan and alginate) and one proteinaceous material (silk) with one dielectric (strontium titanate) and two magnetic (permalloy and magnetite) additives that are relevant for RF materials. The resulting materials were freeze-dried and characterized using scanning electron microscopy to determine film structure and the uniformity of the additive distribution. It was determined that silk electrodeposition gave the best additive uniformity for both magnetic and dielectric additives.
