Multilayer ceramic-polymer microcomposite with improved optical tunability and nanomechanical integrity

Here we report for the very first time the intelligent, novel design and synthesis, microstructural, optical as well as nanomechanical characterization of a multilayer ceramic polymer microcomposite (MLCPMC) structure comprising of a spin coated PEDOT:PSSlayer sandwiched between two spin coated TiO2 layers. The results show that in comparison to the nanomechanical properties of the polymeric PEDOT:PSS layer, spectacular improve-ment in nanomechanical properties is achieved in the MLCPMC structure. In addition, excellent optical tunability is achieved in the MLCPMC structures, without compromising the transmittance in the visible range. Thus, the novel MLCPMC structure may provide a further step towards materials for flexible electronics with additional benefit of extraordinary mechanical integrity. These results are discussed in terms of low temperature phase and microstructure development. Further, the mechanism of spectacular improvement in nanomechanical properties is proposed. Finally, the implications of these unique results for development of intelligently designed multilayered micro/nano composite structures for multifunctional applications in various domains such as strategic, space, military, structural, bio-sensing, OLED devices, DSSCs, flexible electronics and bioelectronic applications; are discussed.
