“…Covering other materials with PPy coatings from chemically derived powder is problematic. The idea to overcome this obstacle was realized by polymer deposition from the gas phase [53] or by the preparation of composites with poly(N-vinylcarbazole) [54], poly(ethylene oxide) [55], polyvinyl chloride [56], poly(vinyl alcohol) (PVA), poly(vinyl acetate) (PVAc) [57], polyurethane [58], carbon black [59] or proteins like silk [60]. Other forms of materials containing PPy are also available, like substituted polymers, self-doped polymers, polymer/macroion materials, and hybrid materials (where the macroion is inorganic, polymeric, or of an organic blend) [61].…”

This review is devoted to polypyrrole and its morphology, which governs the electroactivity of the material. The macroscopic properties of the material are strictly relevant to microscopic ordering observed at the local level. During the synthesis, various (nano)morphologies can be produced. The formation of the ordered structure is dictated by the ability of the local forces and effects to induce restraints that help shape the structure. This review covers the aspects of morphology and roughness and their impact on the final properties of the modified electrode activity in selected applications.

“…Specimens were made of Interglas 92140, a heavyweight twill cloth certified for the aircraft industry, of twill 2×2 structure and high density and weight (2.55 g/cm 3 and 390 g/m 2 respectively). Each specimen used the same type of fibre of the same number of 3 layers, yet of different lay-up.…”

“…The constant development of the composite technology has gradually led to their application in integrated composite aerostructures, with the major advantages of the method including: a reduction in the number of parts and the primary structural weight assembly cost e.g., in civil aircraft, the number of composite elements in an American Boeing 787 amounts to 50% of the total number of parts, and in military aircraft, the composite structure has been used in the forward fuselage of the American F-35 Joint Strike Fighter; furthermore, a cocured skin structure and vertical web are used in the European EP-2000 with a view to substantially improving the validity and reliability of the structural integrity of the aircraft [1]. There are two leading joining methods used in composite structures: mechanical and adhesive [2], [3]. Riveting remains one of the main joining methods in thin-walled aircraft structure applications.…”

Recently, there has been a growing trend towards an ever greater use of composite materials in aircraft structures. This necessitates a search for effective ways of joining these materials. The desirable characteristics of such joints are predominantly high strength and low mass, both of which are features offered by rivet nuts. The study was conducted on one type of glass fabric material, from which two types of composite specimens were prepared. Each specimen used the same type of fibre of the same number of 3 layers, yet of different lay-up. Specimens were joined with aluminium alloy and steel rivet nuts to produce single and multi-row parallel models of riveted joints for further testing and analysis. The specimens were clamped in the grips of tensile machine and subjected to a tensile strength test. In the work, the course of the forces in the rivet nuts joint and the failure modes and effects of joint failure were analysed. The distribution of vertical displacement was examined according to the joint material and two fibre orientation variants. To determine the distribution of displacements, the FE (Finite Element) method was used. Upon completion of the experimental stage, the obtained results were subjected to comparative analysis.

“…They are commonly used as conductors and/or semiconductors in many technological areas such as biosensors, biochips, biofuel cells, and others. 23,27,[29][30][31] Among conducting polymers, polypyrrole (Ppy) is one of the most extensively investigated due to its excellent electrical conductivity, environmental and thermal stability, useful electronic properties, 32 and insolubility in common organic solvents. It has been reported by our group that initially adding [Fe(CN) 6 ] 4À into bulk polymerization solution and then oxidizing it into [Fe(CN) 6 ] 3À by oxidoreductases embedded within the yeast membrane could serve as the pyrrole polymerization reaction initiator.…”
