Optical and structural properties of (PANI‐CSA‐PMMA)/NiNPs nanocomposites thin films for organic optical filters

Abstract

Synthesized nanocomposite of protonated polyaniline with camphorsulfonic acid (PANI-CSA) hosted in poly(methyl methacrylate) (PMMA) and incorporated with nickel nanoparticles (NiNPs) were coated as thin films on activated fused silica substrates using oxygen-plasma and spin coating techniques. Weight percent ratios of 0, 10, 20, 30, 60, and 90% of NiNPs with respect to PANI-CSA thin films have been studied in order to investigate the optical, structural, and morphological properties of (PANI-CSA-PMMA)/ NiNPs by employing UV-Vis spectrometer, XRD, scanning electron microscopy (SEM), contact angle (CA) goniometry, impedance analyzer, and thermogravimetric analysis. Deduced refractive indices (n) from UV-Vis data were in the range from 1.5 up to 2.2. SEM micrographs show the typical crystalline structure of PANI was vanishing gradually with increasing the NiNPs content. Optical properties such as refractive index (n), extinction coefficient (k), absorption coefficient (α) as well as the band-gap energies (E g ) were mathematically deduced throughout the experimental transmittance and absorbance UV-Vis spectra. Calculated refractive indices (n) were in the range from 1.5 up to 2.2. Optical band-gap energies decrease in a monoexponential decay for samples up to 60% NiNPs/PANI-CSA, samples with 90% concentration had substantial drop in its value due to the NiNPs percolations. The incorporation with NiNPs leads to the development of a new morphological states (sheet-like heterostructure) which start to be obvious at 30%, at this concentration the CA was maxima (54 ), at this concentration and the crystallite size are maximum and the CA was maximum (highest hydrophobicity).

Synthesis and Conductivity Studies of Poly(Methyl Methacrylate) (PMMA) by Co-Polymerization and Blending with Polyaniline (PANi)

“…The use of insulating polymers such as PMMA with conducting polymers such as PANi has proven to produce a new composite material not only with good mechanical properties but also with good electrical conductivity [42][43][44]. Thus, processable conducting PMMA has led to the development of a vast number of applications (Table 1).…”

“…The high PANi electrical properties and the high PMMA mechanical features, when combined, can be useful in many applications, such as for the development of optical [44], electronic and optoelectronic devices [41]. The potential of PMMA/PANi cathode material as a substitution to metal was studied by Jia et al (2017).…”

Trends on Synthesis of Polymeric Nanocomposites Based on Green Chemistry

“…This chemical modification generates tailored surface characteristics, such as roughness. Besides, it is possible to graft functional groups or polymers, perform PPL, modify hydrophilicity, synthesize metal coatings directly on the surface of the PNCs [128] and, obtain metal-polymer film [129,130], synthesis of nanocomposites for organic optical filters [131]. The most common parameters for these treatments remain practically the same since the implementation of plasma technology and are as follows: power, gas/monomer flow, elemental gas composition, treatment time, substrate temperature, and reactor type configuration.…”

PANI-CSA/Co3O4 Nanocomposite Films: Optical, Morphological, and Structural Properties

“…Cobalt(II, III) oxide (Co3O4) is an antiferromagnetic solid oxide that is classified as a ferrite of the spinel-type and can be synthesized in nanoparticles (NPs) form with higher catalytic activity and remarkable optical and magnetic properties and they have promising applications in memory devices, electrical switching and microwave devices and sensors [1]. Nanocomposites of organic/inorganic exhibit integral properties between the organic and the inorganic material [2]. Conducting polymers are used in various applications, including optics [3], electronics, actuators, and sensors [4].…”
