Design of highly stabilized nanocomposite inks based on biodegradable polymer-matrix and gold nanoparticles for Inkjet Printing

Abstract: Nowadays there is a worldwide growing interest in the Inkjet Printing technology owing to its potentially high levels of geometrical complexity, personalization and resolution. There is also social concern about usage, disposal and accumulation of plastic materials. In this work, it is shown that sugar-based biodegradable polyurethane polymers exhibit outstanding properties as polymer-matrix for gold nanoparticles composites. These materials could reach exceptional stabilization levels, and demonstrated potent… Show more

“…To avoid this, sodium borohydride was employed as a reducing agent. NaBH 4 is a fast-reducing agent commonly employed for nanoparticle growth in the presence of organic capping agents, from biopolymers to proteins [ 28 , 29 , 30 , 31 ]. The fast reaction time linked to borohydride reactions ensured the formation of small and monodisperse particles.…”

“…Information obtained through the use of UV–VIS techniques should also be complemented with TEM measurements if aggregation and medium effects, both subtypes of optical phenomena, must be distinguished. TEM measurements give information about the presence of AuNP aggregates and morphological changes of the clusters during the synthesis process in the presence of different ligands [ 30 , 45 ]. Employing air-dried samples ensures the elimination of all possible interferences from the suspension medium.…”

“…Also, to predict the rheological characteristics of a drop of ink, the inverse Ohnesorge number Z is used i.e., Z = 1/O h . [51]. As increase in demand of selfcharged and wearable devices,highly functionalized conductiveTi 3 C 2 T x (MXene) has attracted attention to directly prepare a highly stable conductive ink in various organic solvents.…”

“…In order to accomplish certain properties, polymeric tailoring could be carried out directly on biopolymers by chemical derivatization [ 7 , 8 ]. Another option is the preparation of synthetic polymers from their corresponding monomers which can lead to a large range of structures and applications [ 9 , 10 , 11 , 12 ]. These are the reasons why polymeric materials are gaining great relevance in nanotechnology in general and are being used as NP precursors for DDSs.…”
