Nanocompósitos verdes para aplicação em eletrônica flexível

Abstract

In this project, polymeric nanocomposites were made from natural rubber latex reinforced with nanocrystalline cellulose (NCC). Nanocellulose is a very promising material to use as additive on the fabrication of nanocomposites due to its abundance, biodegradability and great mechanical properties. Because of that reason, the utilization of this renewable raw material is even more interesting when applied in natural polymers, leading to environmental benefits. The use of nanocellulose as reinforcement to elastomeric materials improved the mechanical properties of the nanocomposites produced. Carbon electrodes were integrated to the green nanocomposites through direct deposition, aiming the achievement of flexible and transparent electrodes, with excellent electric responses. The materials were characterized on morphological, topographical, mechanical, electrical and adhesive properties between the substrate and nanocomposite.
