“…With the increase of the content of m-rGO nanoparticles the contact density between conductive fillers increased, the conductive path became more, and the conductivity increased rapidly. Results are consistent with the literature (Li et al, 2019). In summary, surface modified reduced graphene oxide nanoparticles loaded UV curable conductive inks based on PUA chemistry were formulated.…”

Printed electronics are emerging technology products that we use in every moment of our daily lives. It is used in many fields from health, textile, electronics to communication. Inks with nanometal or organic content can be used in printed electronics. The ability of printed electronics to withstand temperature makes its use widespread in the electronics industry. Main aim of the study is to combine surface modified graphene oxide-based conductive inks with flame retardant materials. In this study, an effective and simple approach for the preparation of polyurethane acrylate (PUA) screen printing ink containing surface modified reduced graphene oxide (rGO) which has flame retardant activity. A new and effective flame-retardant additive; 9,10-dihydro-9,10-oxa-10-phosphaphenanthrene-10-oxide (DOPO), silane coupling agent and reduced graphene oxide was synthesized. In this synthesis, first reduced graphene oxide was modified with (methacryloyloxy)propyltrimethoxysilane, and then reacted with DOPO to obtain a flame-retardant monomer containing P and Si. Based on the successful modification reactions, screen-printing ink containing polyurethane acrylate and different amounts of modified graphene oxide content (0, 5 and 10 wt%) were prepared and screen printed on the paper surface. In addition, coatings were made on the paper surface to determine some the properties. LOI values, thermal properties, contact angle values, conductivity and surface properties of the obtained prints and coatings films were investigated. As a result, conductive screen-printing ink resistant to high temperatures was successfully produced and printed coatings and free films were formed.

CuS is an encouraging photoelectrode candidate that meets the essential requirements for efficient solar‐to‐hydrogen production, but it has not been thoroughly studied. A CuS light absorber layer is grown by the self‐assembly of copper and sulfur precursors on a carbon paper (CP) electrode. Simultaneously, rGO is introduced as a buffer layer to control the optical and electrical properties of the absorber. The well‐ordered microstructural arrangement suppresses the recombination loss of electrons and holes owing to enhanced charge‐carrier generation, separation, and transport. The potential reaching 10 mA cm−2 in 1.0 m KOH solution is significantly lowered to 0.87 V, and the photocurrent density at 1.23 V is 94.7 mA cm−2. The computational result reveals that the potential‐determining step is sensitive to O* stability; the lower stability of O* in the thin layer of CuS/rGO decreases the free‐energy gap between the initial and final states of the potential‐determining step, resulting in a lowering of the onset potential. The faradaic efficiency for the photoelectrochemical oxygen evolution reaction in the optimized 2CuS/1rGO/CP photoanode is 98.60%, and the applied bias photon‐to‐current and the solar‐to‐hydrogen efficiencies are 11.2% and 15.7%, respectively, and its ultra‐high performance is maintained for 250 h. These record‐breaking achievement indices may be a trigger for establishing a green hydrogen economy.
