Interview with Giulio Cesareo

We plan to expand to professional sport sector to consolidate our brand

UK-based Directa Plus is one of the largest producers and suppliers worldwide of graphene-based products for use in consumer and industrial markets. The company's products are natural, chemical-free and produced sustainably. Commercial applications of the products include smart textiles, tyres, composite materials and environmental solutions. Chief executive officer and founder Giulio Cesareo chats about the thermally-conductive applications of graphene nanoplatelets and the potential they hold across different product categories.

TT: How would you describe the market for graphene nanoplatelets (GNPs) in textiles? What is the size of this market?

The market for GNPs in textiles is still small but with high potential due to the versatility of graphene and the different properties it can bring to fabrics. Applications in the textile industry include electrical and thermal conductivity, bacteriostatic properties and flame inhibiting traits. Directa Plus, a pioneer in developing and promoting G+ GNPs in textiles has been working with a small number of carefully selected partner companies to implement the technology in different parts of the market, focusing from the very beginning on safety, sustainability and on matching existing product demand. There are no consistent data on the market size yet.

TT: Which are your major sectoral markets for G+ printed fabrics and G+ membranes?

At present, the major markets for G+ printed fabrics are sportswear and workwear, while for G+ membranes, they are sportswear, citywear and luxurywear.

TT: What are the main growth drivers of this industry?

The main growth drivers of the graphene industry are: being able to produce the graphene materials in a consistent and competitive way in terms of volumes and price; being able to understand and match market demand; collaboration with different players in the value chain to develop and offer the right graphene materials for each specific application and reduce the time to market; being able to scale-up the technology at the proper time; being able to communicate the benefits of using this technology to the end users; and having more and more brands starting to implement the technology, allowing end-users to experience the benefits of graphene-enhanced products.

TT: What kinds of conductive and smart textiles are GNPs being used for? Where do you see the applications growing?

Currently G+ GNPs are used mainly for thermally-conductive applications in sportswear, workwear and city wear. The scope is to improve the thermal comfort of the user in different climatic conditions, via heat dissipation in hot climates, and by evening out heat distribution and homogenisation in cold ones. In workwear, the user will benefit from this technology and focus on his activity without being affected by the discomfort generated by high or low temperature. Electrical conductivity is still under development but could lead to a new generation of smart textiles (i.e. with data transmission for wearables: graphene would allow lighter garments that are easier and safer to wash if compared to metallic wires), not only in the apparel industry but also in home furniture textiles and in automotives. Since the market is still very small, all these applications have the potential to grow significantly.

TT: What are the main challenges of working with GNPs in textiles? How are you overcoming these?

The main challenges are related to the need of using the right GNP morphology and the proper percentage of nanoplatelets for the right application at a competitive cost. Directa is working to understand market demand, applying state-of-the-art technology and identifying where GNPs can be applied to give maximum benefit to the industry at a reasonable cost. This is part of why Directa invested in producing and certifying its G+ materials as non-toxic and non-cytotoxic, safe for the environment. Directa has also a dedicated advanced development area (ADA), where chemical, physical and textile engineers are collaborating to develop and test the different applications. This is part of the service the company is offering to its customers and business partners.
