Nanotechnology is the frontier of science, technology, engineering, and manufacturing in the nano scale. The technology is still emerging and evolving. Nanotechnology has shown promises of being small, fast, strong, lightweight, and smart, while reliable, efficient, and cost-effective. We have aspirations to introduce many of these attributes in product design. In 2007, our founder surveyed the entire research field and completed an assessment on the impact of Nanotechnology to the Xerox printing business. He published a white paper from the study. The recommendation to create a Nanotechnology team in Webster was accepted by senior management. To date, the content of the white paper has been declassified, expanded, updated and polished. The material has since been organized as a 1-day short course entitled "Nanotechnology and Opportunities for Digital Printing". The course was first offered at the Annual IMI Inkjet Conference in Chicago September 2012 and more recently in Las Vegas February 2014. This course has been shortened to 2-hours and was offered at IS&T's Digital Fabrication and Digital Printing Conferences, NIP30 in Philadelphia September 2014 and NIP31 in Portland 2015.
Many exploratory nano projects were initiated in Webster 2008. One of them was to explore the use of nanomaterials and nanocomposites to radically improve the performance of future printer products. The research conducted included: (transparent) conductive coatings, smart components, and printed electronics. Dr. Law, in collaboration with Dr. M. Kanungo (Xerox), discovered new hole injection reactions between nanomaterials (carbon nanotube and PEDOT) and a hole transport layer. They then invented new digital printing processes based on the hole injection reactions. Majority of this work was published in J. Phys. Chem. C, 115, 23964, 2011; and J. Appl. Phys., 112, 074506, 2012. In addition, the research in nanomaterials and nanocomposites generated tremendous amount of intellectual property value for Xerox.
Our founder began his scientific endeavor researching organic photoconductive materials for printers and copiers. His published work ranges from synthesis to spectroscopy to thin films to device fabrication to electrical measurements to charge generation mechanisms. Dr. Law has hands on experience in many classes of photoconductive materials, such as phthalocyanines, squaraines, azo pigments, and perylenes. Most of the work were published as review articles in the 90s [Chem. Rev. 93, 449, 1993; Handbook of Organic Conductive Molecules and Polymers, H. S. Nalwa edited, John Wiley and Sons, 1997, Ch 10; Organic Photochemistry, Vol 1, V. Ramamurthy and K. S. Schanze edited, Marcel Dekker, 1997, Ch 12 ]. In early 90s, Dr. Law was charted to develop new toner materials, where he studied the mechanisms of tribocharging and charge exchange among polymer particles. He also studied and formulated a variety of electrically conductive materials and low surface energy materials for components in printers.
