Fabrication of fire-retardant building materials via a hyper-crosslinking chemical conversion process from waste polystyrenes

open access: yesEnergy and Built Environment, 2022
Polystyrene (PS) is rich in plastic materials, but it produces a large amount of waste every year, causing a huge burden on the environment. Although PS plastic is the source of a common ''white pollution'' in daily life, it still has a high utilization ...
