“…Therefore, researchers have paid great efforts on how to make GOs into solid hybrid materials to overcome the shortages of their dispersion. The polymer/GO solid-state materials have been fabricated and their physical properties are investigated [13]. The polymer matrices include polyamine-ester [14], poly-imide [15], and epoxy resins [16][17][18].…”

A class of graphene oxide (GO) Ormosil glasses with excellent nonlinear optical properties were made with sol-gel method. The as-prepared GO Ormosil glasses were highly transparent in visible and near-infrared region, due to the uniform dispersion of modified GO in the matrix. These Ormosil glasses have a broadband optical limiting effect from 532 to 1570 nm, with lower optical limiting onset energy density (F ON ). The nonlinear absorption coefficients of the Ormosil glass could reach 210.62, 647.96, and 43.10 cm GW −1 at 532, 1064, and 1570 nm. The optical limiting properties of the Ormosil glasses come from nonlinear absorption proved by Z-scan measurements. Therefore, the Ormosil glasses have potential applications in nonlinear optical areas.

“…Recent reports suggest that more and more electrochromic materials have been found and the optical properties are modified in infrared wavelengths, for instance, VO 2 , viologen, polypyrrole, polyaniline, polythiophene, and so on . Compared to the inorganic materials, organic polymers have more extensive applications, especially the usage areas of organic electrochromic materials [poly(aniline‐co‐ o ‐aniside), poly( o ‐aniside), and poly( o ‐aniside‐co‐ o ‐nitroaniline)] are more extensive due to their multicolor capability, fast switching speed, high optical contrast, and low energy consumption …”

An IR electrochromic film constructed by copolymer of aniline and o‐nitroaniline has been successfully prepared by cyclic voltammetry. The effects of polymerization of aniline and o‐nitroaniline on electrochromic properties and optical properties were investigated by cyclic voltammetry, scanning electron microscopy, FTIR spectrometer, and UV–vis spectrophotometer. The results indicate that the film can exhibit three colors (apple green, dark green, and dark blue) at different voltages of −0.1, 0, and 0.8 V. Simultaneously, a fast response time (1.89 and 4.47 s), a high coloration efficiency, a significant optical modulation (60% between −0.1 and 0.8 V) and a large average emissivity range (Δεmax = 0.203) are achieved for the new film. © 2018 Wiley Periodicals, Inc.

“…Among EMI shielding materials, electrically conductive polymeric composites have recently gained popularity because of their light weight, adjustable resistivity, good flexibility, corrosion resistance, and ease of processing . The EMI shielding effectiveness (SE) of a conducting polymeric composite depends on many factors, such as the conductive filler's intrinsic conductivity, size, aspect ratio, content, distribution, and interfacing action, and so on . In recent years, increasingly more conductive fillers, such as carbon based nanomaterials and metalized carbon materials, have been developed, creating more options for conducting composites .…”

Resistance gradient polymeric electromagnetic shielding composites: Preparation and Characterization

et al. 2018

Based on the principle of Stokes’ law, a series of polyvinyl butyral (PVB)/nickel (Ni) composite films with a resistance gradient were successfully prepared using a suspension casting method with the aid of gravity. Gradient distribution structure, conductive and mechanical properties, and electromagnetic shielding effectiveness (SE) were investigated. Scanning electron microscopy (SEM) observations and energy‐dispersive spectrometer (EDS) detection show that the gradient distribution of Ni particles in the PVB matrix was formed along the thickness‐direction. A surface resistivity difference of 10 orders of magnitude appears between the top surface (PVB‐rich side) and the bottom surface (Ni‐rich side). Percolation transformation occurs in the range of Ni content of 3.0∼4.5 vol% at the Ni‐rich side, which is much lower than that of PVB/Ni composites with homogeneous Ni distribution. The gradient distribution structure grants the composite both good electromagnetic shielding performance and good mechanical properties. When the Ni loading reaches 10.5 vol% in the film, its SE value rises to 30 dB, which is 15 dB higher than that of a homogenous film with the same filler content. It is believed that electrically conductive gradient polymeric composites have potential application value in the field of electromagnetic shielding. POLYM.
