Carbon Based Nanomaterials for High Performance Optoelectrochemical Systems

Abstract

Carbon nanotubes (CNT) and graphene are two significant carbon based nanomaterials which have extraordinary physicochemical properties, used in diverse fields of research. Recently, some actual studies were made to associate these carbon nanomaterials to produce CNT‐graphene hybrid with synergic effects of graphene and CNTs. Addressed herein, EDOT‐modified reduced graphene oxide (rGO), functionalized multiwalled carbon nanotube (f‐MWCNT) and hybrid material (rGO‐f‐MWCNT) have been prepared. Then, PEDOT‐modified composite films were synthesized via electrochemical polymerization to examine enhancing electrochemical properties of PEDOT and characterized by SEM, AFM analysis. As a conclusive finding, an improved stability, charge density, electrochromic switching kinetics and optical contrast of polymer composite films were observed on presence of nanocarbon materials in comparison to the control PEDOT film due to facile ion transport, high surface area.

Synthesis and Characterization of a New Collagen-Alginate Aerogel for Tissue Engineering

“…Different biopolymer-based aerogels have been reported to be used as TE scaffolds; nevertheless, there are some limitations with their use, mainly related with mechanical properties [15]. Nowadays, there has been considerable interest in carbon-based nanomaterials to fabricate a new class of materials with unique properties [20]. In this study, a method to improve the mechanical and biological properties of the scaffold by the incorporation of alginate and GO was used, since it has been previously reported as successful [6,28,[35][36][37].…”

“…Graphene oxide (GO) is a subclass nanomaterial from the graphene family [6,17]; it is an oxidized form of chemically modified graphene [18,19]. It is made out of a single-atomthick layer of carbons with carboxylic acid, oxygen (-O-), and hydroxyl (-OH) groups in its edges [18][19][20][21][22] and oxygen and hydroxyl groups on the basal plane [18,20] allowing chemical interactions, hydrogen bonding, and other surface reactions [18]. GO has the capability to upregulate the degree of proliferation and differentiation of cultured cells, suggesting that GO is a biocompatible substrate [23]; besides mechanical properties of graphene and its derivatives, it could be used to reinforce TE scaffolds [18].…”
