Additive methods for manufacturing materials have recently emerged, particularly for the fabrication of three-dimensional architectures. Because of their long history in thin-film etching and deposition, plasmas offer unique advantages for many of the materials and surface processes associated with additive manufacturing. Here, we review recent efforts that have been primarily focused on the direct writing of patterned structures and the post-treatment of printed materials. Different configurations, materials, and applications are presented. Current challenges and a future outlook are also provided. 3D printing, additive manufacturing, microdischarges, nanotechnology, roll-to-roll

New synergic behavior is always inspiring scientists toward the formation of nanocomposites aiming at getting advanced materials with superior performance and/or novel properties. Carbon nanotubes (CNT), graphene, fullerene, and graphite as carbon-based are great fillers for polymeric materials. The presence of these materials in the polymeric matrix would render it several characteristics, such as electrical and thermal conductivity, magnetic, mechanical, and as sensor materials for pressure and other environmental changes. This review presents the most recent works in the use of CNT, graphene, fullerene, and graphite as filler in different polymeric matrixes. The primary emphasis of this review is on CNT preparation and its composites formation, while others carbon-based nano-fillers are also introduced. The methods of making polymer nanocomposites using these fillers and their impact on the properties obtained are also presented and discussed.

“…This is the case also due to the immanent transformation of micrometer‐sized wrinkles to wires with thicknesses in the nanometer range. Further, the presented proof‐of‐principle allows easy variation of polymers and thereby incorporating many coordination capabilities, finally enabling altered inorganic nanowire composition (e.g., for Ag or Pt nanowires) . In addition, the approach is not only limited to the linearly wrinkled PDMS template, as shown in this paper.…”

Microstructured hydrogel allows for a new template-guided method to obtain conductive nanowire arrays on a large scale. To generate the template, an imprinting process is used in order to synthesize the hydrogel directly into the grooves of wrinkled polydimethylsiloxane (PDMS). The resulting poly(N-vinylimidazole)-based hydrogel is defined by the PDMS stamp in pattern and size. Subsequently, tetrachloroaurate(III) ions from aqueous solution are coordinated within the humps of the N-vinylimidazole-containing polymer template and reduced by air plasma. After reduction and development of the gold, to achieve conductive wires, the extension perpendicular to the long axis (width) of the gold strings is considerably reduced compared to the dimension of the parental hydrogel wrinkles (from ≈1 μm down to 200-300 nm). At the same time, the wire-to-wire distance and the overall length of the wires is preserved. The PDMS templates and hydrogel structures are analyzed with scanning force microscopy (SFM) and the gold structures via scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy. The conductivity measurements of the gold nanowires are performed in situ in the SEM, showing highly conductive gold leads. Hence, this method can be regarded as a facile nonlithographic top-down approach from micrometer-sized structures to nanometer-sized features.
