Problems solved by technology

However, since the processing temperature of polyarylethersulfone materials is often between 350 and 380°C, it is difficult for traditional organic dye molecules to maintain good thermal stability at this temperature, which will easily cause dye decomposition, resulting in high energy consumption and poor color fastness. Low dyeing efficiency, low mechanical properties of materials and environmental pollution
