Composites are relevant to high-performance materials in the aerospace sector and have attracted attention of scientific technological communities. Bentonites present very fine granulometry which enables their use composites. This study showed development water absorbent composite based on sodium polyacrylate, bentonite coated by epoxy resin. Since there gaps quantification near-infrared spectr...

Advances in carbon nanotube (CNT) based composites over the past decade have demonstrated broad potential of utilizing them as multifunctional sensors because their unique electrical properties. This article studies thermoresistive behavior two-component (CNT-epoxy) nanocomposites and hierarchical (CNT-fiber-epoxy) multiscale using situ resistance measurements during thermal cycling from 25 to ...

Cell rolling is an important physiological and pathological process that is used to recruit specific cells in the bloodstream to a target tissue. This process may be exploited for biomedical applications to capture and separate specific cell types. One of the most commonly studied proteins that regulate cell rolling is P-selectin. By coating surfaces with this protein, biofunctional surfaces th...

Split-ring resonators are excellent left-handed metamaterials for significant electromagnetic coupling behavior. In this work, a split-ring resonator prepared with Ni-doped zeolitic imidazolate framework-67/epoxy resin (ZIF-67/ER) was embedded in the top layer to optimize microwave absorption efficiency 2–4 GHz frequency band. The ZIF-67/epoxy served as bottom improve 4–8 Honeycomb conductive c...

Waterborne epoxy resin (WEP) has been widely used as an anti-corrosive coating for metals. However, it is still a big challenge to further improve its anti-corrosion performance due the poor barrier properties corrosive media. In this study, fluorinated graphene (FG) was filler in WEP properties, which contributes corrosion resistance enhancement. The chemical composition and microstructures of...

Wood polymer composites (WPC) are sensitive to moisture because of the hydrophilic nature wood fibers. The main objective this study was improve dimensional stability WPCs by coating. Polypropylene and polylactic acid were reinforced three pulp fibers (kraft, thermomechanical (TMP), chemothermomechanical (CTMP)) at fiber contents (50, 60, 70% w/w). resulting coated using two commercial coatings...

Abstract In recent years, and with the progress of oil natural gas purification processes, it has been noticed that huge quantities sulfur are produced millions tons as byproducts, which is considered a dangerous substance may threaten safety health environment. So, this study aims to maximize elemental benefits in construction applications, especially coating sector. study, modified be used ep...

A new simple experimental approach is proposed for in situ mechanistic studies of the underpaint stability metal/oxide/polymer interface under immersion. It allows an intelligent screening and fast ranking conversion coatings on Zn alloys designed further application organic coatings. The based a electrochemical aging protocol to samples preliminary coated with model epoxy-polymer. latter enoug...
