“…The positions at 3081 cm −1 represent the vibrations of the methyl carbon (–CH 3 ) group. The presence of a sharp prominent band at 1729 cm −1 suggests a good possibility of the existence of carbonyl (C=O) stretching from –COOH functional group in the shell part of the copolymer [ 48 , 49 ]. The characteristic peaks that are observed in the fingerprint region at 1031 cm −1 and 910 cm −1 wavenumbers are attributed to C–O–C symmetric stretching vibration, which is associated with the C-COOCH 3 group of MMA located at the shell region of nanoparticles [ 50 ], the intensities of these peaks are weak because of the small amount of MMA monomer involved in the synthetic process, while the peak at 1604 cm −1 can be associated with –C=C stretching vibrations of aromatic double bond in styrene molecule.…”

Structural-coloured poly(styrene-methyl methacrylate-acrylic acid) (Poly(St-MMA-AA)) deposited carbon fabrics (Poly(St-MMA-AA)/PCFs) with fascinating colours (salmon, chartreuse, springgreen, skyblue, mediumpurple) changing with the (Poly(St-MMA-AA) nanoparticle sizes can be facilely fabricated by the thermal-assisted gravity sedimentation method that facilitates the self-assembly of Poly(St-MMA-AA) colloidal nanoparticles to generate photonic crystals. The particle sizes of Poly(St-MMA-AA) copolymer with core/shell structure varying from 308.3 nm to 213.1 nm were controlled by adjusting the amount of emulsifier during emulsion polymerisation. The presence of the intrinsic chemical information of Poly(St-MMA-AA) copolymer has been ascertained by Raman and Fourier Transform Infrared (FT-IR) Spectroscopy analysis. Colour variation of the as-prepared structural-coloured carbon fabrics (Poly(St-MMA-AA)/PCFs) before and after dipping treatment were captured while using an optical microscope. The structural colours of Poly(St-MMA-AA)/PCFs were assessed by calculating the diffraction bandgap according to Bragg’s and Snell’s laws. The Poly(St-MMA-AA) photonic crystal films altered the electrical properties of carbon fabrics with the resistivity growing by five orders of magnitude. The differential electrical resistivity between Poly(St-MMA-AA)/PCFs and wet Poly(St-MMA-AA)/PCFs combined with the corresponding tunable colours can be potentially applied in several promising areas, such as smart displays, especially signal warning displays for traffic safety.

“…As a result, the nucleation of the terpolymer colloidal particles was predicted to occur via homogeneous nucleation mechanism [27,28]. The improvement made to polystyrene (PS) by the complete infiltration of butyl-acrylate/acrylic acid into the interstice of its structure introduced some level of polarity between the non-polar PS interior and the polar PBA/PAA exterior [29]. As such, the ultimate morphology of the terpolymer microspheres was accordingly anticipated to be a core-shell structure [15] (Figure 1).…”

The generation of three-dimensional superb packages of compact hexagonal periodic assembly with multifaceted layers was demonstrated using Poly (styrene-butylcrylate-acrylic acid) on glass substrates. The synthesized P(St-BA-AA) microspheres were used to formulate a fast drying UV curable terpolymer microspheres printing ink for the generation of colloidal crystal microdots on ink-jet paper with remarkable colours. The terpolymer microspheres and their formulated terpolymer ink undergo self-assembly to form blue monochromatic and viewing angle dependent tunable colours, thus affirming the photonic nature of the generated colloidal crystal films. Unlike other printing techniques which usually make use of specialized tools, this study generated a well ordered coloured tunable assembly of spherical shaped core-shell colloidal crystal microdots on the surface of an inkjetpaper by manually writing the as-synthesized P(St-BA-AA) UV curable printing ink microdots on it. The TEM analysis showed core and shell sizes of 198/50nm and 176/30nm for P(St-BA-AA) 1 and P(St-BA-AA) 2 respectively. Whenever the prepared terpolymer microspheres are used within the heating and transition temperatures of 383 C and 110 C, their thermal stability is retained. This simple technique of generating crystals microdots on inkjet paper may find use in optical devices, security applications and other colour coating applications.

“…The coloured PCs were generated following a published procedure (Ifijen et al, 2019). Here, P(St-BA-AA) crystal films were generated from the assynthesized latexes via the evaporative induced selfassembly of colloidal suspension made from P(St-BA-AA) latex and water on the surface of glass slides.…”

“…The observed peaks at 2924 cm-1 and 3027 cm-1 are caused by methylene and aromatic C-H groups respectively. The peaks at 1725cm-1 and 1198 cm-1 are caused by carboxylic acid (C=O stretch) and C-O stretching vibration (ester bond) (Ifijen et al, 2019) respectively. Figure 4 revealed the SEM micrographs of the fabricated photonic crystal films with insets of coloured films and their multi-layer views.…”

“…The manipulation of either the refractive index or lattice constant by thermal (Dai et al, 2011, Markos, 2016, optical (Kim et al, 2018), and mechanical stimuli (Kim et al, 2018) can be carried out in order to tune the structural colours from the PCs. Previous studies have shown that a colour tunable PC is easier to obtain than PC with monochromatic colour (Ifijen et al, 2019). This study, therefore, fabricated series of highly ordered three-dimensional monochromatic photonic colours from crystals of poly (styrenemethylmethacrylate-acrylic acid) colloidal microspheres via the vertical deposition technique.…”

A one-pot synthetic procedure was successfully used to synthesize monodispersed poly (styrene-butyl acrylate-acrylic acid) (P (St-BA-AA)) colloidal spheres via emulsion polymerization. A glass transition temperature (Tg) of 108 o C was obtained by DSC analysis. Core-shell morphology was revealed by TEM micrograph. Evaporative induced self-assembly process was used to fabricate photonic crystals from the as-synthesized P (St-BA-AA) latexes. Microscopic analyses of the fabricated photonic crystal films revealed the assembling of colloidal particles which rearranged into a fascinating compact three-dimensional periodic hexagonal structure with manifold layer arrangement. The photonic crystal films displayed mesmerizing monochromatic yellow, blue and green colours which were obtained by controlling the size of the microspheres. The prospect of deliberately obtaining photonic crystals with monochromatic colours would be very useful in the generation of photonic crystals for sensing application.
