“…In contrast, with similar ink composition, the graphene inks can unpin the contact lines so that the coffee-ring effects are suppressed. [21] This clear difference between graphene and MoS2 inks is interesting and deserves further extensive studies.…”

“…As a matter of fact, in spite of experimental attempts in the field, [14,23,24] no efficient inkjet printing technology has been demonstrated for mass production of MoS2 patterns/devices in sub-mm scale. In this work we combine the solvent exchange [21,26] and polymer stabilization [27] techniques developed for graphene dispersions to address the above issues concerning inkjet printing of MoS2. First, bulk MoS2 powders are exfoliated in DMF through bath sonication and high-speed centrifugation to obtain thin and small MoS2 nanosheets.…”

“…The attained concentration of 0.1 mg/mL and simultaneous stability period of one week have already approached the best quality of MoS2 dispersions. [2] We regard EC as an excellent stabilizer for MoS2 inks because it can also improve the uniformity of printed patterns, [21,22,27] prevent flake restacking, [28] and importantly, be readily removed through a simple annealing [21,22,27] so that the residual contamination is insignificant.…”

A simple and efficient inkjet printing technology is developed for molybdenum disulfide (MoS2), one of the most attractive two-dimensional layered materials. The technology effectively addresses critical issues associated with normal MoS2 liquid dispersions (such as incompatible rheology, low concentration, and solvent toxicity) and hence can directly and reliably write uniform patterns of high-quality (5-7 nm thick) MoS2 nanosheets at a resolution of tens of micrometers. The technology efficiency facilitates the integration of printed MoS2 patterns with other components (electrodes), and hence allows fabricating various functional devices, including thin film transistors, photoluminescence patterns, and photodetectors, in a simple, massive and cost-effective manner while retains the unique properties of MoS2. The technology has great potential in a variety of applications, such as photonics, optoelectronics, sensors and energy storage.

“…[9][10][11][12][13] The knowledge of conductivity scaling in composites (or percolation systems) comprising CNPs is crucially important for many applications. At present, the overwhelming majority of studies 5,9,14-17 employ a power law to describe the conductivity σ of a CNP percolation system in the form as…”

PostprintThis is the accepted version of a paper published in Nanoscale. This paper has been peer-reviewed but does not include the final publisher proof-corrections or journal pagination.Citation for the original published paper (version of record):Li, J., Östling, M. (2015) Conductivity scaling in supercritical percolation of nanoparticles: not a power law. The power-law behavior widely observed in supercritical percolation systems of conductive nanoparticles may merely be a phenomenological approximation to the true scaling law not yet discovered. In this work, we derive a comprehensive yet simple scaling law and verify its extensive applicability to various experimental and numerical systems. In contrast to the power law which lacks theoretical backing, the new scaling law is explanatory and predictive, and thereby helpful to gain more new insights into percolation systems of conductive nanoparticles.
