Zein-thymol nanofiber films were prepared by electrospinning in this study. The microstructure, contact angle, water vapor transmission rate, and the rate of releasing anti-bacterial substances from the film were investigated. The results showed that when the mass ratio of zein to thymol was 10∶1, the film exhibited a slow-releasing property. Moreover, the water vapor transmission rate of the film was 4.32 g·mm/(m2·h·kPa), and the contact angle was 104.36°. This demonstrated that the zein-thymol nanofiber film had good air permeability and hydrophobicity. Furthermore, the antibacterial effect of the film on Escherichia coli was effective when the ratio of zein to thymol was in a range of 5∶1-1∶1. The minimum and maximum diameters of inhibition zone was 8.68 mm and 20.42 mm, respectively. Besides, due to the safety of the film, it is suitable for medical purpose, such as medical wound dressings.
