Permanent irreversible structural color based on core–shell chemically bonded SiO2@P(St-BA) particles†
Abstract
Novel core–shell chemically bonded SiO2@P(St-BA) particles were designed and self-assembled to prepare photonic crystals. Due to the irreversible collapse of polymer shells during hot-pressing, SiO2@P(St-BA) particles could provide new ideas for high-stability and bright red-shifted structural color patterns.
