“…Values given in [17] are used: 300 ± 60 MPa and 0.3, respectively. Therefore, from these values, the piezoelectric constant d 31 defined by (8) is 43.6 ± 10 pC/N in Experiment 1 and 42.7 ± 10 pC/N in Experiment 2.…”

“…A great effort was made in previous work by the authors [8,9,17] in order to choose the most suitable materials and optimizing the mixture percentage between the active material (piezoelectric) and the binder (polymer) of the sensor. For this particular case, the active material is a piezoelectric ceramic PZT (lead zirconate titanate) provided by Piezo Kinetics Inc. (Bellefonte, USA) with the name of PKI-502, commonly known as "Navy type II".…”

“…The specialized applications of coatings are almost unlimited, and developments of special effect pigments offer new possibilities for the design of functional coatings [73,74]. In this context, infrared (IR)-ref lective pigments are in great demand for the development of "cool roof" coatings, while ultraviolet (UV)-resistant coatings have been developed for outdoor applications [75].…”

Today, many objects that we come across in our daily lives, including the house in which we live and the materials we use (e.g., toothbrushes, pots and pans, refrigerators, televisions, computers, cars, furniture) all come under the "umbrella" of coated materials. Likewise, fields such as military applications -for example, vehicles, artilleries and invisible radars -and aerospace products such as aircraft, satellites and solar panels all involve the widespread use of coated materials. Clearly, the importance of coatings has increased hugely during the modern era of technology.Coating is defined as a material (usually a liquid) which is applied onto a surface and appears as either a continuous or discontinuous film after drying. However, the process of application and the resultant dry film is also regarded as coating [1]. Drying of the liquid coating is mostly carried out by evaporative means or curing (cross-linking) by oxidative, thermal or ultraviolet light and other available methods. Paint can be defined as a dispersion that consists of binder(s), volatile components, pigments and additives (catalyst, driers, f low modifiers) [2]. The binder (polymer or resin) is the component that forms the continuous film, adheres to the substrate, and holds the pigments and fillers in the solid film. The volatile component is the solvent that is used for adjusting the viscosity of the formulation for easy application. Depending on their compositions, paints can be divided into three groups: solvent-borne, water-borne and solvent-free (100% solid). Solvent-borne paints consist of resin, additives and pigments that are dissolved or dispersed in organic solvents. Similarly, in water-borne paints the ingredients are dispersed in water. In solvent-free compositions, the paints do not contain any solvent or water and the ingredients are dispersed directly in the resin.The properties of coating films are determined by the types of binders, pigments and miscellaneous additives used in the formulation. Moreover, types of substrates, substrate pretreatments, application methods and conditions of film formation

“…Numerous papers have described the preparation and characterization of ceramic/polymer composites, most of them aimed at their application as sensors, transducers or actuators [3][4][5][6]. The findings published in the literature indicate that ceramic/polymer composites have potential technological applications in several areas because they can be obtained as flexible film.…”

Composite films were prepared by two different routes: lead zirconate titanate (PZT) particles coated with polyaniline (PAni) dispersed in a polymeric matrix of polyvinylidene fluoride (PVDF); and PZT particles and PAni powder dispersed separately in the polymer matrix. The electrical conductivity of the particles was controlled by the protonation and de-protonation of PAni in solution with controlled pH. The results indicate that the percolation threshold of the composite made of PZT coated with a conductive layer (PZT-PAni) is in the range of 20 vol.% to 30 vol.% of PZT-PAni. The PZT-PAni/PVDF composite redoped in solution with pH 3.7 showed the best results in terms of longitudinal piezoelectric coefficient (d 33 ) in samples containing 30 vol.% of ceramic particles due to the equilibrium between conduction and poling effects on the composite. The poling process of the composite sample required just 5 MV/m electric field applied during 15 min. Furthermore, the composite was used as sensor in structural health monitoring (SHM), showing the possibility to propose it as a functional material.
