Synthesis of a novel cationic short-chain fluorocarbon surfactant and its synergistic effect with hydrocarbon surfactants for enhanced foam performance

Short-chain fluorocarbon surfactants are key alternatives to long-chain fluorocarbon surfactants, while the research on their cationic formulations remains limited. This study synthesizes a novel quaternary ammonium cationic short-chain fluorocarbon surfactant ( PFH-QAC ) and enhances its performance by compounding...
