Hydrogels are functional materials suitable for a wide range of applications due to their good properties and biocompatibility. Recently, attention has also been focused on the research and preparation of electro-responsive hydrogels, mainly based on biopolymers. The diploma thesis presents examples of electro-responsive hydrogels and their potential applications. As part of the experimental work different mixtures of nanocellulose hydrogels and carbon-based conductive additives were prepared. Based on electrical measurements, we determined the specific electrical resistivity and conductivity of the hydrogels and acknowledged that the addition of graphene nanoplatelets and reduced graphene oxide significantly increased the electrical conductivity of the hydrogels. The hydrogel with added graphene nanoplatelets proved to be the most conductive.
