Efeitos da modificação a plasma sobre superfícies de nanocelulose bacteriana: fundamentos e aplicações

Abstract

Bacterial nanocellulose (BNC) stands out as one of the most promising biopolymers due to its wide range of applications, spanning from the textile and food sectors to biomedical and tissue engineering fields. Its intrinsic properties, such as high mechanical strength, biocompatibility, biodegradability, and high water-holding capacity, make it a versatile and highly attractive material. However, these same characteristics may pose limitations, especially when the surface properties are not suitable for the intended application. In this context, plasma modification emerges as an effective strategy for tailoring BNC surface properties, enabling both the reduction and enhancement of its wettability, as well as introducing new functionalities such as antimicrobial activity. This review discusses the structure, synthesis parameters, and properties that make BNC a unique material, emphasizing how plasma etching and thin-film deposition techniques can modulate its surface characteristics, thus expanding its potential for applications in various fields, particularly in textiles, biomedical devices, and food packaging.
