Presentation Abstract:

Anupam Mukherjee*, Hsiu-Pang Yeh , Hao-Yang Yang General Silicones Co., Ltd. , No.9-1, Lane 52, Nan-Kang St., Hsiang-Shan, Hsinchu City, 30095, TAIWAN, R. O. C.

The demand for flexible, stretchable and wearable electronics has been growing up rapidly in recent years. With the significant development of stretchable electronic devices, elastic polymeric materials like PDMS (silicone rubber) [1] or a PU (polyurethane) [2] has provided most promising platforms for flexible and printed electronics. At present, these two novel emerging substrates have received the great attention for both the industrial and academic communities [3] and constant innovations are in progress for the integration with the electronic devices. However, these two substrates have their own limitations related to stretchability, durability, roll to roll process & manufacturing capability, surface and interfacial properties etc. An ideal solution is still an essential need, but shortage in the market. Here, we’re introducing Compo-SiL® [4], a layer-structured, roll to roll, transparent composite material of silicone and polyurethane. By the combination of these two elastomers with different properties, Compo-SiL® is showing great capabilities and diverse possibilities as being an encapsulant as well as a substrate for flexible or stretchable printed electronics. Also, the features and functionalities of silicone can be modified through blending by fillers or grain transfer printing. Here, we are also demonstrating an application for long-term durable and high consistency capacitive stretching sensor by blending silicone with conductive fillers and layer-by-layered structure with polyurethane. In summary, with our revolutionary Compo-SiL® series product, electronic circuit could be embedded with any standard fabric allowing more functional, more comfortable with unprecedented freedom in wearable electronic design. We have further applied this new technology as stretching sensor for the soft electronic application areas.

Biography:

Dr. Mukherjee has a strong background of achievement in synthetic organic chemistry and material science for optoelectronic applications. Following Undergraduate, Masters Study and one year pharma based industrial experience in his native India, he took a step to study for his PhD in Taiwan, at Department of Chemistry in National Tsing Hua University and then a postdoctoral research at Department of Chemistry at Chung Yuan Christian University. After completing a multi-faceted PhD broadly based on transition metal catalyzed organic transformation using gold and platinum and their optoelectronic applications, he had carried out extensive research in the area of Masked Ortho-benzoquinones (MOBs) strategy in organic synthesis. His in-depth interest to search for a new interdisciplinary research field, led Mukherjee to join OLED based world renowned company Luminescence Technology Corporation in Taiwan as a senior researcher where he worked on development of innovative organic optoelectronic materials & design and production for new product development along with the enhancement of interdisciplinary researches in Chemistry, Physics, Materials Science and Electronic Engineering.

Currently, in General Silicones as Technical Director, Mukherjee is engaged in corporate entrepreneurship to develop new ideas and opportunities within established business  and carrying out investigations on design and development of various innovative large-scale manufacturing of high value silicone products following multi-manufracturing processes (Roll to roll calander, Extrusion, Injection and Compression molding). Under his leadership, a dynamic team oriented interdisciplinary group has developed an unique substrate & material, Compo-SiL®, a roll to roll, transparent composite material of silicone and polyurethane which has opened up great capabilities and diverse possibilities as being an encapsulant as well as a substrate for flexible or stretchable printed electronics with market segmentation in flexible electronic, medical and smart textile industry. Through collaborative work between industry and academia, he is developing high level of successful collaboration towards potential market.
