Atomically thin 2D materials, currently being at the forefront of scientific and technological interest, can be categorized as metallic, semimetallic, semiconducting, insulating, or superconducting, depending on their chemical composition structural configuration. They also exhibit, in some cases, a transition from an indirect to direct bandgap alignment when bulk materials are scaled down monolayers. An important class is layered metal dichalcogenides (TMDs) with tunable bandgap, because...
Here, for the first time, novel improvement in processing of polymer nanocomposite based on 2D materials as fillers leading to manufacturing by melt mixing is described.Two new strategies were used insert pre-exfoliated material into matrix, liquid-phase feeding (LPF), and solid-solid deposition (SSD).Initially, graphene oxide (GO) polystyrene (PS) templates polymer, respectively.Traditional characterizations (tensile mechanical test, molecular weight, rheological measurements transmission...
Naturally occurring van der Waals crystals have brought unprecedented interest to nanomaterial researchers in recent years. So far, more than 1800 layered materials (LMs) been identified but only a few insulating and naturally LMs were deeply investigated. Phyllosilicate minerals, which are class of natural abundant LMs, recently considered as low-cost source nanomaterials. Within this family an almost barely explored material emerges: phlogopite [KMg3(AlSi3)O10(OH)2]. Here we carry out high...
Surface properties are extremely important for materials applied in the biomedical areas such as poly(vinyl alcohol)—PVA. The precise control of surface characteristics on these may adjust and expand its applications. Here, we present a new strategy to tune alcohol)/graphene oxide (PVA/GO) films by manipulation GO particles (amount level oxidation) also situ reduction GO. Adopting different approach from methods currently proposed, process was carried out exposing PVA/GO hydrazine vapor...
Niobium disulfide is a layered transition metal dichalcogenide that being exploited as two-dimensional material. Although it superconductor at low temperatures and demonstrates great potential to be applied catalyst or co-catalyst in hydrogen evolution reactions, only few reports have demonstrated the synthesis of few-layer NbS2. However, before applications can pursued, essential understand main characteristics obtained material its stability under an atmospheric environment. In this work,...
Polymer nanocomposites are widely studied for improving and developing novel materials. Incorporation of nanofillers in polymer matrices impart strong behavioral changes, with the extent dispersion fillers polymers playing a key role. This not only limits amount filler one can incorporate but also often leads to enhancement some material properties at expense others. Herein, first time, thermoplastic polyurethane (TPU) graphene oxide (GO) improved abrasion resistance ductility produced by...
Polymer nanocomposites based on 2D materials as fillers are the target in industrial sector, but ability to manufacture them a large scale is very limited, and there lack of tools up manufacturing process these nanocomposites. Here, for first time, systematic fundamental study showing how inserted into polymeric matrix order obtain using conventional industrially scalable polymer processing machines leading large-scale described. Two new strategies were used insert pre-exfoliated material...
