Description

General description

Polycaprolactone (PCL) is a semi-crystalline linear resorbable aliphatic polyester that is composed of repeating units of hexanoate. It has good mechanical properties, miscibility, and biodegradability. PCL is a soft and hard-tissue compatible material that can be used in sutures and drug delivery systems.

Application

PCL can form a nanocomposite with graphene for the fabrication of biodegradable systems for bone tissue engineering.

Features and Benefits

Biodegradable polymer
Non-toxic, biodegradable in soil, broad miscibility, mechanical compatibility with many polymers and good adhesion to a broad spectrum of substrates.
