   Abstract : This thesis work explores electrical conductors based on few-layer graphene flakes as an enabler for low-cost, mechanically flexible, and high-conductivity conductors in large area flexible and printed electronic devices. The flakes are deposited from aqueous solutions and processed at low temperature. READ MORE

5. 3. Inkjet Printing of Graphene-based Microsupercapacitors for Miniaturized Energy Storage Applications

   Author : Szymon Sollami Delekta; Mikael Östling; Jiantong Li; Donald Lupo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; graphene; supercapacitor; microsupercapacitor; energy storage; printed electronics; printing technologies; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Printing technologies are becoming increasingly popular because they enable the large-scale and low-cost production of functional devices with various designs, functions, mechanical properties and materials. Among these technologies, inkjet printing is promising thanks to its direct (mask-free) patterning, non-contact nature, low material waste, resolution down to 10 µm, and compatibility with a broad range of materials and substrates.

   Abstract : Since the discovery of graphene, substantial effort has been put toward the synthesis and production of 2D materials. Developing scalable methods for the production of high-quality exfoliated nanosheets has proved a significant challenge. READ MORE

7. 5. Liquid-Phase Exfoliation of Two-Dimensional Materials : Applications, deposition methods and printed electronics on paper

   Author : Viviane Forsberg; Magnus Norgren; Luis Miguel Pereira Nunes; Mittuniversitetet; []
   Keywords : molybdenum disulfide MoS2 ; transition metal dichalcogenide TMD ; thin films; inkjet printing; 2D inks; liquid-phase exfoliation; shear exfoliation; printed electronics; organic electronics; PEDOT:PSS; photoresponse; photocurrent; cathodoluminescence;

   Abstract : After the unprecedented success of graphene research, other materials that can also be exfoliated into thin layers, like Transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2), have also become the subjects of extensive studies. As one of the most promising methods for large scale production of such materials, liquid-phase exfoliation (LPE) has also been the subject of extensive research and is maturing as a field to the point that devices using additive manufacturing and printed nanosheets are often reported.
