全氟化合物(PFCs)分子中所有氢原子都被氟原子取代。这种取代使得分子具有高度的化学惰性和热稳定性。全氟化合物通常具有极低的表面张力、高电介质常数以及优异的耐腐蚀性能,因此在许多工业和科学领域中得到广泛应用。
全氟化合物可以分为全氟烷烃和全氟化物。全氟烷烃只含有碳-氟键,被用作润滑剂、油漆、涂料和防止油污污染的涂层。常见的全氟烷烃包括全氟辛基磺酰氟(PFOS)和全氟辛酸(PFOA)等。全氟化物中除碳-氟键以外,还含有其他元素,如氧、氮、硫等,常被用作特种涂料、密封材料、电子器件的绝缘材料以及火箭推进剂等。
部分全氟化合物具有持久性、生物积累性和潜在毒性,特别是全氟辛基化合物(PFAS),如PFOS和PFOA等。欧盟、美国、加拿大等国家和地区已经制定了针对全氟化合物的管控法规。中国也积极响应,制定了相关检测标准和限值要求。
