Synthesis of quaternary fluoroalkyl phosphonium salts with high thermal stability and their application as antibacterial agents for polycarbonate (PC)

Two kinds of quaternary fluoroalkyl phosphonium salts with different fluoroalkyl chain length were synthesized as antibacterial agents for polycarbonate (PC). Both of these quaternary fluoroalkyl phosphonium salts had sufficient thermal stability under PC processing temperature, and the quaternary f...
