PChem Associates, Inc.

OUR TECHNOLOGY:

PChem’s technology includes novel materials (inks), print processing trade secrets, and know how that in total provide PChem with a competitive advantage in the exciting and rapidly growing printed electronics market space. The heart of PChem’s technology is the Company’s patented silver nanoparticles. The conductive inks derived from these uniquely stabilized silver nanoparticles

enables PChem to provide their customers with a cost and performance (superior conductivity and ultrafine resolution) advantage in various printed electronic applications including simple consumer devices, as transparent electrodes in solar and lighting products, and sensors in medical and automotive products. HOW IT WORKS:

PChem’s disruptive technology is enabled by the method by which the metal nanoparticles are stabilized in situ during synthesis. The patented production method and proprietary ink formulation technology enable unique attributes and inherent advantages to the materials. APPLICATIONS:
Next-generation solar power systems:

PChem’s novel silver nanoparticle conductive inks can be used as the top electrode of a photovoltaic system (represents ~2/3 manufacturing cost of the system) in organic photovoltaics, thin film, and Si wafer solar power systems. Compared to incumbent material, PChem technology is:

- More cost effective (up to 67% less expensive)

- Environmentally friendly, water based and lower-input processing at commercial volumes

- Superior in its conductivity and flexibility, enabling more robust and efficient solar cells. Smart packaging:

PChem’s technology enables novel new applications in smart packaging including sensors and interactive pharmaceutical packaging, due to PChem’s inherent advantages, including:

- Significant cost advantage based on lower-input (raw materials and energy) process

- Quantum speed advantage vs. current screen-printing technology enabling extreme volumes

- Ability to print on many flexible substrates including paper

- Environmentally friendly, water-based technology. Lighting:

PChem’s technology can greatly enhance the commercial viability of organic light emitting diode (OLED) and other lighting solutions and accelerate the growth of vast new commercial and consumer markets. Compared to incumbent material used in OLED lighting, PChem technology is:

- More cost effective and able to be processed in large format

- Superior in its conductivity and flexibility, enabling more efficient and brighter lights. Consumer Electronic Devices:

Simple consumer electronic devices like small promotional toys for children and interactive games can be enabled by PChem’s technology. “Extreme” volumes in the billions are made economically feasible because of PChem’s technology, which enables:

- Printing on inexpensive packaging substrates

- Cost effective products that are robust and durable to stand up to extreme handling
Electromagnetic Interference/Radio Frequency (EMI/RF) Shielding:

The highly conductive films possible using PChem’s inks can greatly enhance the EMI/RF shielding effectiveness (SE) of even very thin films. In cases where very high SE is required, PChem’s technology can enable significant cost savings because as much as 75-90% less raw material (i.e., silver) can be applied in order to achieve the same SE as a polymer thick film (PTF) ink. Where less SE is required, or where transparent conductive films (TCF) can be used for shielding, PChem’s printed TCF again enables significant cost savings as it uses less raw material. In addition PChem’s TCF are more flexible and generally have higher optical transparency. Compared to incumbent material, PChem’s technology enables:

- A significant cost advantage

- Flexible, highly transparent, and highly conductive films for many shielding applications
