Flexible pigment-nanocellulose substrate for printed electronics with good thermal tolerance
Abstract
In printed electronics, most of the components andstructures are printed on substrates made of syntheticmaterials, such as plastics, ceramics or silicon. Here wepresent a micro/nanocomposite substrate, which consistsof inorganic pigment fillers and nano-fibrillar cellulose(NFC) and demonstrate the feasibility of the substratefor printed electronics applications.The composite structure can contain up to 90% pigmentfiller being still mechanically stable and flexible. Heatand pressure are used to make the surfaces smooth andglossy with a plastic-like feel. The resulting surfacesare smoother than the smoothest paper surface in themarket (photo paper), and the dimensional stability as afunction of moisture is significantly better than fortraditional paper. The composite sheets have a goodthermal tolerance because of high amount of stableinorganic pigments. Additional benefit of the substrateis its good printability. In case of the pigment-NFCsubstrates, the solvent of the ink can penetrate to thestructure and there is no significant spreading of theink.Two pigment types were used to address the effect of rawmaterials on substrate smoothness and porosity.Precipitated calcium carbonate (PCC) gives smoothersurface than kaolin pigment. However, the structureformed using PCC is more porous leading to a weakerconductivity of printed structures. The effect ofdifferent pigment particle sizes on substrate propertieswill be discussed in a more detail. We will alsodemonstrate the feasibility of the pigment-NFC substratefor printed electronic structures (RFID tags).Characteristics of the printed structures will bepresented and compared to the ones printed on referenceplastic substrates.The combination of a good dimensional stability with alow surface roughness, a high thermal tolerance, lowmaterial costs and good printability makes thesebiodegradable substrates potential for printedelectronics applications. In particular, they couldreplace oil-based plastics in some applications.
