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.
Synonyms: 2-Oxepanone homopolymer; 6-Caprolactone polymer
Linear Structural Formula: (C6H10O2)n
Melting Point: 56-64 C; 60 C (lit.)
Application: PCL can form a nanocomposite with graphene for the fabrication of biodegradable systems for bone tissue engineering.
