Incorporating graphene in polymer nanolaminates paves the way for the development of effective electromagnetic interference shields
The incorporation of centimetre-size monolayer graphene in polymer nanolaminates, paving the way for the development of effective electromagnetic interference (EMI) shields, has been published in Nature Communications
Direct-Deposited Graphene Oxide on Dental Implants for Antimicrobial Activities and Osteogenesis
Graphene, a honeycomb-lattice monolayer comprising aromatic ring carbon atoms, is a potential biomaterial owing to its unique physical and chemical properties
Development of graphene-PVDF composite membranes for membrane distillation
A novel PVDF-graphene composite membrane has been developed. Specifically, a commercial PVDF polymer has been suitably functionalized with the aromatic rings of styrene (PVDF-f) and characterized by spectroscopic techniques. This new material has been used as a base...
Graphene-coated aluminum thin film anodes for lithium-ion batteries
We present a detailed study on graphene-coated aluminum thin films for Li-ion battery anode applications. The best electrode ageing behavior is obtained for Al films encapsulated with four porous graphene layers. Graphene encapsulation prevents “crushed” Al...
Hydrophobicity of graphene as a driving force for inhibiting biofilm formation of pathogenic bacteria and fungi
Objective. To evaluate the surface and wettability characteristics and the microbial biofilminteraction of graphene coating on titanium.Methods. Graphene was deposited on titanium (Control) via a liquid-free technique. Thetransfer was performed once (TiGS), repeated...
Graphene-based stretchable and transparent moisture barrier
We propose an alumina-deposited double-layer graphene (2LG) as a transparent, scalable, and stretchable barrier against moisture; this barrier is indispensable for foldable or stretchable organic displays and electronics. Both the barrier property and stretchability...
Complete long-term corrosion protection with chemical vapor deposited graphene
Despite the numerous reports on the topic, examples of chemical vapor deposited (CVD) graphene-based anticorrosive coatings able to provide long-term protection (i.e., several months) of metals are still unavailable. Here, we finally present a polymer-graphene hybrid...
Graphene onto medical grade titanium- an atom-thick multimodal coating that promotes osteoblast maturation and inhibits biofilm formation from distinct species
The time needed for the osseointegration of titanium implants is deemed too long. Moreover, the bacterial colonization of their surfaces is a major cause of failure. Graphene can overcome these issues but its wet transfer onto substrates employs hazardous chemicals...
Nanoporous atomically thin graphene membranes for desalting and dialysis applications
Dialysis is a ubiquitous separation process in biochemical processing and biological research. State-of-the-art dialysis membranes comprise a relatively thick polymer layer with tortuous pores, and suffer from low rates of diffusion leading to extremely long process...
Graphene-Armored Aluminum Foil with Enhanced Anticorrosion Performance as Current Collectors for Lithium-ion Battery
Aluminum (Al) foil, as the most accepted cathode current collector for lithium-ion batteries (LIBs), is susceptible to local anodic corrosions during long-term operations. Such corrosions could lead to the deterioration or even premature failure of the batteries and...
Graphene-based nanolaminates as ultra-high permeation barriers
Permeation barrier films are critical to a wide range of applications. In particular, for organic electronics and photovoltaics not only ultra-low permeation values are required but also optical transparency. A laminate structure thereby allows synergistic...
