“…The SnO2 NPs are regularly distributed on the SWCNT, as shown in Figure 2b. However, in some areas, the SnO2 NPs are specifically agglomerated at points where the carbon nanotubes have a close bond, which has also been seen in our previous work [22], where the NPs agglomerated at defect points onto the surface of carbon nanowalls. The transfer of pixels in a controlled manner, and insight on the morphological properties of the LIFT-printed single-walled carbon nanotubes and hybrid SWCNT@SnO2 are essential in applications aimed at practical devices.…”

Ammonia is one of the most frequently produced chemicals in the world, and thus, reliable measurements of different NH3 concentrations are critical for a variety of industries, among which are the agricultural and healthcare sectors. The currently available technologies for the detection of NH3 provide accurate identification; however, they are limited by size, portability, and fabrication cost. Therefore, in this work, we report the laser-induced forward transfer (LIFT) of single-walled carbon nanotubes (SWCNTs) decorated with tin oxide nanoparticles (SnO2 NPs), which act as sensitive materials in chemiresistive NH3 sensors. We demonstrate that the LIFT-fabricated sensors can detect NH3 at room temperature and have a response time of 13 s (for 25 ppm NH3). In addition, the laser-fabricated sensors are fully reversible when exposed to multiple cycles of NH3 and have an excellent theoretical limit of detection of 24 ppt.

This paper describes a rapid, solvent-free laser based procedure for the fabrication of reproducible sensitive sensors based on hybrid nanocomposites, i.e. single walled carbon nanotubes (SWCNTs) decorated with tin oxide nanoparticles (SnO2 NP) that overcomes challenges associated with solvent-assisted chemical functionalization and integration of these materials into devices. The gas response of the LIFT-ed SWCNT: SnO2 sensors has been evaluated at room temperature and an enhanced 2 fold response to ammonia as compared to the SWCNT sensors is demonstrated. Spontaneous and full recovery of the hybrid nanocomposite signal after exposure to NH3 is achieved without any post treatment. The theoretical detection limit of the LIFT-ed SWCNT: SnO2 sensors at room temperature is calculated to be 0.59 ppb. These results indicate that LIFT is an excellent technique which shows great promise towards advancing future developments in the field of chemical sensors.

“…Several studies have proved the feasibility of LIFT for printing liquids with a wide range of viscosities (from 1 to 10 6 mPa s), [ 33–35 ] and suspensions containing large loading particles (up to 30 µm). [ 36–38 ] Thus, SP inks—with high viscosity (>10 Pa s) and usually loaded with large particles (a few micrometers)—can be printed using LIFT, [ 39–43 ] though not through IJP. [ 19,20 ] These rheological properties are compatible with high solid contents, and in the case of conductive inks, they can result in the fabrication of interconnects with sheet resistances as low as 50 mΩ □ −1 , [ 5,44–46 ] much lower than those resulting from IJP (around 1 Ω □ −1 ).…”

Inkjet printing (IJP) is the most widespread direct‐write technique in paper electronics. However, this technique cannot be used for printing devices on untreated regular paper, since its low‐viscosity nanoinks leak through the cellulose fibers. Thus, a planarization coating is frequently used as a barrier, even though this makes substrates more expensive and less eco‐friendly. Alternatively, high solid content screen printing (SP) inks could allow printing on regular paper due to their high viscosity and large particle size; however, they cannot be printed through IJP. Another digital technique is then required: laser‐induced forward transfer (LIFT). This work aims at proving the feasibility of LIFT for printing devices on regular paper. The main transfer parameters are systematically varied to obtain uniform Ag‐SP interconnects, whose performance is improved by a multiple‐printing approach. It results in low resistances with much better performance than those typical of IJP. After optimizing the functionality of the printed lines, a proof‐of‐concept consisting of a radio‐frequency inductor is provided. The characterization of the device shows a substantially higher performance than that of the same device printed with IJP ink in similar conditions, which proves the potential of LIFT for digitally fabricating devices on regular paper.
