“…The size and concentration of these nanoparticles can also have a significant impact on the energy conversion efficiency of the PVDF film. For example, increasing the concentration of carbon nanotubes within the PVDF matrix can increase energy conversion efficiency by increasing the number of potential exciton energy transfer pathways [18]. Additionally, using nanoparticles with carefully engineered energy levels can enhance the efficiency of the energy conversion process by reducing the amount of energy lost in the form of heat.…”

In this work, a synthesis technique for highly homogeneous PVDF-CaFe2O4 polymer films direct from solution was developed. The structural characterizations were conducted using XRD, FTIR, and ESEM experimental techniques. The XRD characteristic peaks of CaFe2O4 nanoparticles revealed a polycrystalline structure. The average crystallite size for CaFe2O4 was calculated to be 17.0 nm. ESEM micrographs of PVDF nanocomposites containing 0.0, 0.25, 0.75, and 1.0 wt% of CaFe2O4 showed smooth surface topography. The direct Edir and indirect Eind band gap energies for the PVDF-CaFe2O4 nanocomposites were decreased with the additions of 0.0–1.0 wt% CaFe2O4. In addition, the refractive index (n0) increased from 3.38 to 10.36, and energy gaps (Eg) decreased from 5.50 to 4.95 eV. The nonlinear refractive index (n2) for the PVDF-CaFe2O4 nanocomposites was improved with the addition of CaFe2O4 nanoparticles, exceeding those reported in the literature for PVC, PVA, and PMMA nanocomposites. Therefore, the PVDF-CaFe2O4 nanocomposites are expected to take the lead in optoelectronic applications because of their unusual optical properties.

“…As demonstrated by MacDiarmid [22] CNTs are ideal candidate to fill the polymers because they can increase their electrical conductivity by many orders of magnitude from 10 −10 -10 −5 up to 10 3 -10 5 S/cm. CNTs improve the strength properties of the polymer and make it a stable electroconductive material [14] [23].…”

“…There are different chemical and mechanical methods to prepare CNT/polymer nanocomposites [13] [14], depending on polymer properties, which is the main factor in the filling process. Anyway it is necessary to have high dispersion of CNTs in the polymer matrix and to create a network of CNTs, which play an important role in electrical conductivity of material [15].…”

The article reports the results on the development of highly optimized two-factor mechanical method of dispersion of multiwalled carbon nanotubes (MWCNTs) in polymer matrixes with the aim of preparing of nanocomposites. The investigation of the MWCNTs and nanocomposites was carried out by using scanning electron microscopy, X-ray diffraction and Raman spectroscopy. The effectiveness of the developed method is demonstrated by comparing the electrical conductivity of MWCNT/polymer nanocomposites prepared on the basis of polydimethylsiloxane (PDMS) and the epoxy resin, using two methods-the known chemical and the proposed one-two-factor mechanical.

“…To provide both conductivity and biocompatibility, research has been conducted to hybridize multiple substances and to confirm their effects [122,123]. A CNT-CP composite material can impart conductivity and show superior synergistic conductivity compared with CP and CNT, according to the results of a recent research for developing a conductive hydrogel [124]. Nevertheless, these materials have been widely used because of the high charge characteristics of CP or CNTs [125].…”

In the field of tissue engineering, conductive hydrogels have been the most effective biomaterials to mimic the biological and electrical properties of tissues in the human body. The main advantages of conductive hydrogels include not only their physical properties but also their adequate electrical properties, which provide electrical signals to cells efficiently. However, when introducing a conductive material into a non-conductive hydrogel, a conflicting relationship between the electrical and mechanical properties may develop. This review examines the strengths and weaknesses of the generation of conductive hydrogels using various conductive materials such as metal nanoparticles, carbons, and conductive polymers. The fabrication method of blending, coating, and in situ polymerization is also added. Furthermore, the applications of conductive hydrogel in cardiac tissue engineering, nerve tissue engineering, and bone tissue engineering and skin regeneration are discussed in detail.
