The application relates to the field of biological medicine, and discloses a pH response phase transition sulfonic acid liposome for destroying a virus envelope structure as well as a preparation method and application thereof. The liposome is composed of dioleoyl phosphatidyl ethanolamine, (2,3-dioleoyl-propyl)-trimethylammonium chloride, oleic acid, sodium hexadecyl sulfonate and cholesterol. The liposome constructed by the application can neutralize viruses in the form of adhesion and wrapping of viruses in a high-pH environment in the early stage of virus infection, is endocytosed by cells, and is phase transitioned in lysosomes to realize intracellular inactivation of the viruses. In a low-pH microenvironment of inflammatory tissues caused by the late stage of virus infection, the liposome can directly destroy the virus envelope to realize virus inactivation through phase transition outside cells after adhesion of the viruses. Therefore, the liposome can realize effective killing of viruses in the early stage and the late stage of virus infection, has a spectrum antiviral effect, and has a wide application prospect.
