Sustainable and recyclable polymer coloring system via size-tunable, pigment-encapsulated silica microspheres: enabling circular economy of plastics
Hirohisa Iwabayashi, Kenji Okada, Arisa Fukatsu, Ryohei Mori, Masahide TakahashiA “recyclable-by-design” platform using size-coded, pigment-embedded silica microspheres enables high-purity polymer recovery and multi-color sorting via mild dissolution and sieving, preventing plastic downcycling for a true circular economy.
