A Simple Method to Functionalize PCL Surface by Grafting Bioactive Polymers Using UV Irradiation

摘要

Background: Polycaprolactone (PCL) is a biodegradable polymer which is used in tissue engineering applications thanks to its many favorable characteristics. However, PCL surfaces are known as hydrophobic leading to a lack of favorable cell response. To overcome this problem. PCL surfaces will undergo a surface functionalization by grafting bioactive polymers bearing ionic groups.
