Abstract
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 inkjet-paper 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.
Highlights
Materials that can regulate the flow of light due to their periodic dielectric structural nature are known as Photonic crystals [1, 2]
This study reports on the fabrication of a fast drying P(St-butyl acrylate (BA)-acrylic acid (AA)) UV curable colloidal printing ink microdots with colour tuning property on inkjet-paper substrate using a very simple and precise technique
2.405g of AAm, 0.0481g of BIS, 0.012g of DMAP and 4.27ml of EG was added to P(St-BA-AA) microspheres (11.1g) containing 10.91 wt% P(St-BA-AA) terpolymer microspheres and thereafter, blending in an ultrasonic bath was carried out for 15min
Summary
Materials that can regulate the flow of light due to their periodic dielectric structural nature are known as Photonic crystals [1, 2]. Low cost production of two and three-dimensional photonic crystals with wide areas and distinct shapes can be generated from colloidal self-assembly technique [12, 13, 14]. This approach habitually results in materials with ordered particles and captivating properties. Ink-jet printing has emerged, as an attractive technique for fabricating coloured photonic crystals on substrates especially on polythene and paper surfaces [22, 23] This technique depends on the careful deposition of colloidal based ink on a temporary surface in the form of droplets
