One of the most frequently used conducting polymers, polypyrrole, can take part in chemical processes with typical components of ambient media: oxygen, acids, bases, redox reactants, water, and organic vapors; it can also incorporate nonreactive ions and surfactants from solutions. The influence of such processes on changes of the polymer structure, composition and on possible degradation is analyzed. The benefits and disadvantages of such processes for analytical characteristic of polypyrrole based electrochemical sensors are considered. This discussion is focused on potentiometric ion sensors, where polypyrrole is either a receptor membrane or an ion-to-electron transducer placed between a solid state electrode support and a typical ion-selective membrane.

“…Electrochemical deposition of metals on electrodes by conducting polymers such as PPy and PAn has been well studied. [7][8][9][10][11][12][13] Electroless deposition for the recovery of metals has also been reported in which polymer films are oxidised by metal ions of relatively high oxidation potential, effectively reducing the metal to its neutral form. Silver, [14][15][16] gold [17] and palladium [18][19] have proved successful in this procedure.…”

Polypyrrole and polyaniline conducting polymer composites with individual fibres of cellulose have been successfully prepared and characterised. For this, individual Kraft paper pulp fibres have been fully encapsulated with polypyrrole and polyaniline by direct polymerisation of the respective monomers using ferric chloride and ammonium persulfate as the oxidants. These novel conducting polymer/cellulose fibre composite materials exhibit the inherent properties of both components. They include the electrical and chemical properties of polypyrrole and polyaniline and the strength, flexibility and available surface areas of the cellulose fibre. This allows for interesting opportunities for the development of new added-value products in the paper and packaging industries. Additionally, by utilising the redox active surface of

Hybrid functional materials, constituting both inorganic and organic components, are considered potential platforms for applications in extremely diverse fields such as optics, micro-electronics, transportation, health, energy, energy storage, diagnosis, housing, environment and the highly relevant area is Internet of Things (IoT). Material properties of hybrid materials can be tuned by modification of the composition on the molecular scale to produce smart materials. Cross-cutting approaches, to synergistically couple molecular engineering and processing allows to tailor complex hybrid systems of various shapes with perfect control over size, composition, functionality, and morphology. The detailed description and discussion of variety of hybrid functional organicinorganic materials and their contribution in the designing of specific modern technologies is the prime focus of this review. There is an enormous demand for hybrid materials to provide technological breakthroughs with the most sought after being the enabling of the IoT. Interest in the field of IoT will witness exponential growth over the next decade as markets realize the true potential of realtime data acquisition for various entertainment, knowledge dissemination, defense, environmental, and healthcare applications. Many of the well-established materials, such as metals, 1 ceramics, 2-4 or plastics 5,6 cannot fulfill all technological desires for the various new applications. In addition to the early interest in structural hybrid materials based on carbon-silicon networks, many recent efforts have centered on the design of functional hybrid materials which harness the chemical activity of their components. This approach has been successfully used in recent years in the design of hybrid polymers 7 with special emphasis on structural hybrid materials based on mixed silicon-carbon networks prepared by sol-gel methods [8][9][10][11][12] which can also entrap additional active species. 13 In this field the stakes are high and scientists aim at producing structural materials with properties between those of inorganic glasses and organic polymers.8 But the expectations go beyond mechanical strength and thermal and chemical stability. These new materials are also sought for improved optical, 14-17 and electrical 18,19 properties, luminescence, 12,20-25 ionic conductivity, [26][27][28] and selectivity, 29-32 as well as chemical [33][34][35] or biochemical 36-38 activity. Chemical activity is of core importance in functional materials. Sensors, selective membranes, all sorts of electrochemical devices, from actuators to batteries or supercapacitors, supported catalysts or photoelectrochemical energy conversion cells are some important devices based on hybrid functional materials.Hybridization is a multifaceted strategy. In some cases, conducting organic polymers act just as a solid polymeric support for active species, whereas in other hybrid systems the activity of organic and inorganic species combines to reinforce or modify each other. But in every case ...
