Graphene Glass Radiant Heaters - Is This The future? (Printed Electronics USA 2016)

Graphenes have elevated the science of producing resistive-based elements.

Considerable differences have existed between heater elements. In the context of space heating most heating systems fail to convert 100% of their input energy into heat. A kilowatt of convection heat is prone to heat loss by air circulation and has poorer heat transfer properties when compared to a kilowatt of radiated heat. While both units of output can be a kilowatt, their heat transfer properties vary considerably in efficiency.

Electric space heating has a variety of challenges.

Heraeus graphene enabled inks and pastes provide an efficient effective element for resistive heating. The Pilkington Graphene Glass enabled resistive heater demonstrated on The Heraeus stand operates in the high 90% efficiency range and its performance can be easily verified by analysis of the radiant output of the glass panel heater versus the power being consumed. It is also an advantage that heaters supported by graphene-enabled elements are designed to work only at one temperature for which the internal architecture can be optimized. The glass panel, heat transfer method is radiant, with negligible convection and low-enough "watt density" of heat to create acceptable comfort levels close to the radiator panel, with a non-directional dispersion of radiated heat to objects in the room. This allows the whole room itself to warm up with overall temperature and running time controlled by a thermostat. The Perpetuus graphene enabled Heraeus ink is also available to be applied to other substrates employing conventional coating and printing methods for use as heating elements for white goods, automotive, marine and aerospace applications.

Keith joined Heraeus in 2013 and has been instrumental in the development and commercialization of polymer thick film products within Heraeus Electronics. Prior to joining Heraeus, Keith had worked as a Senior Formulation Chemist at Engineered Materials Systems and Applications Manager at T-Ink. Keith gained diverse experience during his many years at Electro Materials Corporation of America (EMCA) where he held roles as Manufacturing Manager and Research Manager for polymer thick film inks. He has a Bachelors of Science in Chemistry.

Graduated from University of the West of England with 1st Class honours in Forensic Chemistry in 2012 after completing a dissertation in printed sensors and electrochemical testing. Rebecca worked at Gwent electronic materials from July 2012 until January 2015 on Graphene projects in partnership with Perpetuus. Projects included conductive graphene pastes for various printing applications such as screen and flexo printing, PEDOT:PSS clear conductor and Graphene electroluminescent lamps. Rebecca moved to work directly for Perpetuus as Senior Research Chemist in January 2015 and has worked solely on the development of highly conductive Graphene printing inks for the screen, flexo and die slot coating industry. The inks have been tested for a wide range of applications including but not exclusively, electronics, biosensors, heating panels and batteries.

Heraeus manufactures Clevios™ PEDOT conductive polymers, specialty silver inks, highly conductive graphene based inks, and a full line of polymer thick films for electronics. Applications include printable electronics, touch technologies, antistatics, OLEDs and 3rd Generation solar cells. Clevios™ for touch devices combined with low temperature silver ink for bus bars and innovative flexible printed electronic applications will be highlighted by Heraeus.
