Composite Coating Structure for Durability Enhancement of Flexible Devices 

Over the recent years, demand for flexible devices has grown rapidly in various technological applications including wearable computers, flexible displays and solar cells. Because these devices are typically packaged with polymeric materials, they are prone to physical damage due to contact and bending stresses experienced during usage. Thus, mechanical durability becomes an important issue to overcome to achieve sufficient reliability for commercialization of flexible devices. In this presentation, coating structures in the form of a composite that may be utilized for flexible device applications are discussed. The effectiveness of a discrete coating structure that allows for sufficient light transmission as well as flexibility is presented. Rather than using a continuous coating, the concept is to use a discretely structured coating so that large angle bending is allowed without causing excessive tensile stress to accumulate within the coating. Also, the flexible property of thin materials is exploited to achieve adequate flexibility with good surface durability. It is expected that surface durability of polymeric flexible materials will be greatly enhanced by using these types of composite coating structures.

Engineering Ceramics and Their Composites - Tailoring Material Variables for Tribological Application  

This presentation will provide an overview of the experimental results from our groups, where we will demonstrate the microstructure-toughness-wear correlation in some of the model ceramic systems. Specific examples of the case studies from our own research will be provided to demonstrate how humid atmosphere or high temperature environment influence the wear properties of structural ceramics of cutting tool cermets, respectively. Towards the end of the presentation, some interesting and recent experimental results on cryogenic wear of brittle ceramics will be presented. In order to demonstrate the tribological properties of ceramics in cryogenic environment, the results of a planned set of sliding wear tests on self-mated Al2O3, ZrO2 and SiC in liquid nitrogen will be discussed. A comparison will also be made with the results of some control experiments carried out at ambient conditions.
