Hong Kong Patent Secured for Liquid-Exfoliated Nanomaterials

Advanced Material Development Limited (AMD) is delighted to announce the successful grant of its Hong Kong patent for Liquid-Exfoliated Nanomaterials, marking a significant milestone in the company’s mission to deliver sustainable nanotechnology solutions to global industries. This latest patent adds to AMD’s growing portfolio across the US, Europe, India, and China, further validating the company’s pioneering work in advanced materials.

John Lee, CEO of AMD, commented “These inks form the backbone of AMD’s printed RFID antenna technology, designed to replace traditional metallic inks with water-based nanocarbon formulations. Securing this patent strengthens our leadership in sustainable printed electronics, enabling real-world environmental impact across RFID, sensors, and smart packaging. Importantly, Hong Kong serves as a gateway to key Asian markets where demand for this technology is accelerating.”

At the core of this advancement is AMD’s proprietary nHance™ platform, which enables the scalable liquid-phase exfoliation of nanomaterials to produce high-performance, application-specific inks. Unlike conventional metal-based RFID tags, AMD’s carbon-based inks offer multiple advantages:

• Sustainability: Printable on compostable substrates such as paper or card, supporting circular economy goals.
• Flexibility: Chemically stable and mechanically robust, suitable for diverse substrates and demanding environments.
• Non-Metallic Design: Ideal for sectors like food and pharmaceuticals where the presence of any metal is critically important.
• Adaptability: Addresses performance challenges such as detuning tolerance near conductive materials, and includes variants optimised for metal proximity and textile applications — enabling cost-effective deployment across retail, logistics, and industrial sectors.

This patent further positions AMD at the forefront of sustainable materials innovation, underpinning the company’s mission to deliver scalable, environmentally responsible technologies for global supply chains.
