“…The photovoltaic (PV) inkjet printing inks (IP) contain a complex mix of materials, solvent and surfactants that keep the p-type and n-type components de-mixed (Hashmi et al 2015;Ö zkan et al 2016). A piezoelectric laboratory scale drop-on-demand (DoD) materials inkjet printer (Dimatix 2831-DMP) was used to test the printability of the plasma treated MNFC films .…”

Nitrogen plasma surface treatment for improving polar ink adhesion on micro/nanofibrillated cellulose films

We find that nitrogen plasma treatment of micro/nanofibrillated cellulose films increases wettability of the surface by both liquid polar water and nonpolar hexadecane. The increased wetting effect is more pronounced in the case of polar liquid, favouring the use of plasma treated micro/nanofibrillated cellulose films as substrates for a range of inkjet printing including organic-based polar-solvent inks. The films were formed from aqueous suspensions of progressively enzymatic pretreated wood-free cellulose fibres, resulting in increased removal of amorphous species producing novel nanocellulose surfaces displaying increasing crystallinity. The mechanical properties of each film are shown to be highly dependent on the enzymatic pretreatment time. The change in surface chemistry arising from exposure to nitrogen plasma is revealed using X-ray photoelectron spectroscopy. That both polar and dispersive surface energy components become increased, as measured by contact angle, is also linked to an increase in surface roughness. The change in surface free energy is exemplified to favour the trapping of photovoltaic inks.

Versatile Method for the Simultaneous Synthesis of Two Ionic Liquids, Otherwise Difficult to Obtain, with High Atom Economy

et al. 2019

A new synthetic approach and full spectral (NMR, IR, MS) and ion chromatographic characterization (IC) of nitrogen‐based ionic liquids bearing allyl‐ or ethyl‐ substituent and triflate, tosylate, methyl sulfate or methanesulfonate anion has been presented. On a sample of 16 new ionic liquids, the versatility of the anion exchange method has been proven. In the metathesis reactions that have been carried out, the halide anion was exchanged in ionic liquid with an alkyl sulfonate based anion using alkylating agents. The results obtained using ion chromatographic analysis on the newly synthesized compounds have been discussed. Also, the utilization of a gaseous methyl halide by‐product, obtained in the metathesis reaction and otherwise difficult to synthesize, has been presented. This approach ensured high atom economy of the overall process, which makes the proposed methodology sustainable and eco‐friendly.

“…Despite the high power conversion efficiencies (PCEs) achieved by devices fabricated with TiO 2 photoanodes [6][7][8], the intrinsic low carrier mobility of TiO 2 is a matter of great concern [9,10]. This issue has led many researchers to probe the development of alternative photoanode materials.…”
