Abstract:

 

Recently, research aimed at obtaining flexibility and functionality in displays, sensors, and photocatalytic devices has attracted considerable interest owing to the developments in the fields of organic materials and nanotechnology. The flexible substrate, which supports the functional device, is the most critical component for the development of ultimate flexible devices. Until now, several materials have been studied as flexible substrates, which include plastic materials such as PET (polyethylene terephthalate) and PEN (polyethylene naphthalate), as well as inorganic materials, such as metal foil and thin glass. Considering the ultimate curvature, device process, convenience, and productivity, plastic is the most suitable material for flexible substrates. However, plastic substrates cannot withstand high processing temperatures and hence, their applications are limited. This talk will be composed as in below; a) theoretical approach of solubility based on Hansen solubility parameters, b) new method for the fabrication of flexible devices using water-soluble ceramic thin films especially focused on NaCl and MoO3, c) fabrication of nano-pattern and its applications using water-soluble nano-crystal, and d) future plan.
