Both Graphene and Graphyne are 2-D allotropes of carbon that hold exciting promise in a variety of fields, but subtle differences in their structure make a significant impact in how they function. Learn more about the key differences between Graphene and Graphyne on our blog:
Graphene Nanoplatelets (GNP) are short stacks of platelet-shaped graphene sheets. The stack size and shape are what sets this product apart from graphite as it provides barrier properties and the graphene component makes it an excellent conductor. When exfoliated Graphene Nanoplatelets are added to polymers, they add electrical and thermal conductivity, reduce gas permeability, and improve mechanical properties, such as tensile strength and surface hardness.
Measurements of the intrinsic strength of Graphene consistently indicate it’s the strongest material ever discovered. Its simple structure paired with the enormous strength of the individual bonds within, results in very few structural defects across its surface.
Graphene’s strength in combination with its other electrical and mechanical properties open the door for many exciting applications. ACS Material has a range of high-quality Graphene products available for researchers around …

Graphene aerogel (GA) is considered to be the lightest solid material and consists of 99.98% volume of air; it is so light that it can be balanced on even the smallest of plants. They are commonly low in density and thermal conductivity but make excellent insulators as they are almost completely comprised of gases. GAs are also very elastic but can go back to its complete, original form after being compressed. Due to its light weight, graphene has been proposed as a substitute for the …
Graphene is a single layer, two-dimensional crystal allotrope consisting of pure carbon atoms that is only one atom thick, revealing a hexagonal shape resembling a honeycomb. The first method to obtain a single-crystal graphene (SCG) was found by mechanically exfoliating a graphite crystal with adhesive tape and it has been the most efficient way of producing the cleanest, atomically thin nanosheets of layered materials.1 Repeated peeling is necessary but it is not easy to determine the number …
