Biobased Photonic Whitener

Photonic color is a fascinating concept that involves manipulating light at the nanoscale level to create a range of colors. Natural and synthetic materials alike can exhibit this phenomenon, from the iridescent wings of butterflies to the vivid hues of peacock feathers. While TiO2 is a commonly used pigment, its manufacturing process is highly energy-intensive and generates significant waste. This has prompted efforts to find alternative materials, and photonic pigments have emerged as a promising solution, drawing inspiration from nature's coloration strategies. Unlike conventional absorptive colorants that are prone to fading, photonic pigments offer greater stability and sustainability, particularly in the production of water-based paints. The ultimate objective of bio-resourced photonic whitener is to replace TiO2 through agreen synthesis process that utilizes bio-based materials.
