Thomas Swan & Co. Ltd., one of the UK’s leading independent chemical manufacturers, has built on the previously announced portfolio of patents for the separation of atomically thin 2-dimensional materials, including graphene and Boron Nitride, by today announcing that it has now been granted a US patent [US10,822,238B2] for the production of these atomically thin 2-dimensional materials, using high shear liquid phase exfoliation using their high-volume homogeniser technology.
Thomas Swan’s patents in this area are part of a growing portfolio of international rights in the evolving graphene (and other 2D materials) processing arena. As the challenge to deliver more high-performance composite materials increases, adopting graphene as an additive often demands processing of critically fine laminar particle grades demonstrating superior features and enhanced levels of performance. The Graphene Nanoplatelets (GNP) delivered in various forms using this high-shear processing technique adopting homogenisation technology is a stronghold for the Durham based manufacturing company.
This use of homogenisation in the production of graphene though high shear liquid phase exfoliation builds upon its exclusive licensing of the original patented core exfoliation technology developed with Trinity College Dublin, and puts Thomas Swan in the unique position in owning this production space.
Michael Edwards, Commercial Director – Advanced Materials at Thomas Swan said, “Adding this US patent to our extensive portfolio of 2D materials processes, but specifically graphene nanoplatelets [GNP], places us in a strong global position. Our GNPs can be used as additives in multiple diverse applications, offering the commercial adoption of bulk graphene. The process patents deliver a modular, scalable production capability in our ISO-standard manufacturing operation. We are in the ideal position to support the market demand and we will continue to work with our partners in this field to further develop our unique market position.”
