HydroGraph reports successful testing of its fractal graphene in electromagnetic interference (EMI) shielding

HydroGraph Clean Power has announced successful testing of its flagship product, FGA-1, fractal graphene, in electromagnetic interference (EMI) shielding.

The integration of HydroGraph’s graphene in epoxy resin was reportedly able to achieve substantial EMI shielding properties by reaching an 80-decible (dB) attenuation (a reduction of signal strength during transmission) in shielded enclosures of less than 1 mm thick. Minimum ratings for consumer protection are 30 dB and ranges from 60 dB to 80 dB for automotive and aerospace applications.

GrapheneUP launches next-gen graphene-enhanced formulations for textile industry

This is a sponsored post by GrapheneUP

Population growth and improved living standards require solutions for textiles with new functions to meet changing needs. Wherever they are used, graphene-based smart textiles provide added value in terms of improved performance or comfort. GrapheneUP®, a leading graphene company with the largest production of few-layer graphene in Europe, has developed and introduced into the market new graphene-based products for textile industry: INKGUP® Fabric and PRINTGUP®.

INKGUP® Fabric is graphene-based coating formulation for textile industry produced with few-layer graphene GUP®, designed to provide superior finishing properties. This formulation has been certified antiviral (ISO 18184:2019) also for SARS-CoV-2, antistatic and with excellent abrasion resistance and thermal regulation properties.

Several properties of textiles are improved using the formulations developed with GrapheneUP®, in particular the thermal regulation, abrasion resistance, EMI shielding, UV protection, excellent electrical conductivity, antibacterial and antiviral properties.

Versarien launches graphene-based superparamagnetic material

Versarien has announced the launch of a new hybrid nanomaterial that has superparamagnetic properties, which can be used across a range of applications, like defense and healthcare. The new material combines graphene with both iron oxide and manganese oxide nanoparticles and its development was led by Versarien's 62% owned subsidiary, Gnanomat.

The superparamagnetic material combines graphene with both iron oxide and manganese oxide nanoparticles that provide the material with magnetic properties. In return, graphene provides electrical conductivity to these electrically insulating metal oxides. Magnetic nanocomposites can readily respond to external magnetic fields which allow them to be manipulated. Potential applications of the material include the treatment of wastewater whereby pollutants are adsorbed onto the graphene surface. The material could also lends be used in biomedical and biotechnology applications, or defense applications requiring the shielding of electromagnetic fields. Magnetic manipulation could allow the recovery and recycling of the graphene, something that could not be done with normal graphene compounds.
