“…High energy ionizing radiation such as proton, 13 gammaray, [14][15][16][17][18][19][20] UV treatment, [21][22][23][24][25] and X-ray 15 has been utilized as an alternative approach for tailoring the structural and electrical conductivities of the lms. Usually, these approaches are temperature independent and in turn results in material with higher purity.…”

“…All the fitting parameters and their respective formulas obtained by loading–unloading curves have been illustrated in our previous study. 22 The as-prepared P-GMA-NGP polymer nanocomposite films were further investigated by load–displacement curve. The nanoindentation method was adopted to analyze the load–depth data by depth sensing of the films using a sharp Berkovich indenter.…”

“…Thus, the judicial selection of processing route diminishes the interfacial tension and suppresses the agglomeration between the filler and the matrix. 16−21 In last few years, we have attempted novel processes such as melt mixing, swift heavy ion irradiation, 22 and click chemistry 23,24 for providing a high density of the interfaces and strong covalent linkages between the filler and the matrix.…”

Polymer nanocomposites (PNCs) have become an exciting field of current research and have attracted a huge interest among both academia and industry during the last few decades. However, the multifunctional single-nanocomposite film exhibiting the combination of desired structure and properties still remains a big challenge. Herein, we report a novel strategy to address these problems by using versatile polymer glycidyl methacrylate (GMA) as a bridging medium between the filler and the polymer matrix, resulting in high density of interfaces as well as strong interactions, which lead to generation of tunable thermal, mechanical, and electrical properties in the materials. The nanocomposites prepared by GMA bridging exhibit the remarkable combination of thermal ( T d = 342.2 °C, T g = 150.1 °C ), mechanical ( E = 7.6 Gpa and H = 0.45 Gpa ) and electrical (σ = 3.15 × 10 −5 S/cm) properties. Hence, the conjugation approaches related to GMA bridging facilitate a new paradigm for producing multifunctional polymer nanocomposites having a unique combination of multifunctional properties, which can be potentially used in next-generation polymer-based advanced functional devices.

“…In addition, with a conductivity exceeding 1000 S·cm –1 , PEDOT:PSS approached the characteristics of ITO and is considered as an appropriate alternative for a convenient replacement for ITO in a number of applications, including as electrodes in solar cells with active organic materials [ 17 , 18 , 19 ]. For the same purpose, PEDOT:PSS is modified by treatment of various external exposure (ion irradiation, gamma-ray irradiation, UV irradiation) [ 21 , 22 , 23 ] or by additional processing using organic and inorganic acids, such as acetic acid, propionic acid, butyric acid, oxalic acid, sulfurous acid, and hydrochloric acid, etc. [ 24 , 25 , 26 , 27 , 28 ].…”

Improving the Conductivity of the PEDOT:PSS Layers in Photovoltaic Cells Based on Organometallic Halide Perovskites

Among conductive polymers, PEDOT films find the widest application in electronics. For photovoltaic applications, studies of their optical properties, stability, and electrical conductivity are of greatest interest. However, the PEDOT:PSS transport layers, when used in photovoltaic cells, have a high electrical resistance, which prevents solar cells from increasing their efficiency. One of the promising ways to improve their electrical properties is the use of composite materials based on them, in which the conductivity can be increased by introducing various additives. In this work, conductive polymer films PEDOT:PSS (poly (3,4-ethylenedioxythiophene):polystyrene sulfonate acid) doped with a number of amines (Pentylamine, Octylamine, Diethylamine, Aniline with carbon nanotubes) were obtained and studied. It is shown that, depending on the concentration of dopants, the electrical conductivity of PEDOT:PSS films can be significantly improved. In this case, the light transmission of the films practically does not change. The process of improving the conductivity by treating the surface of the finished film with amines, followed by heat treatment, was studied. It is assumed that the improvement in conductivity is the result of the self-assembly of monolayers of organic molecules on the surface of the PEDOT:PSS film leading to its p-doping due to intermolecular interaction.
