摘要：
The lipase was immobilized on nano-silca and used as a modifying agent for epoxy resin. The effect of modification was evaluated by measuring the enzyme activity, physical properties and corrosion inhibition of coatings. As a result, the activity of lipase reached 2300 U/g, the hardness of coating reached level two and the adhesive force reached level three. The resistance reached the highest and was significantly higher than unmodified epoxy resin when 2% mass fraction immobilized lipase was added, which indicated that the immobilized lipase improved corrosion inhibition of epoxy resin. © 2017, Editorial Office of Acta Petrolei Sinica(Petroleum Processing Section).
