Polycaprolactone (PCL) is a semi-crystalline, hydrophobic, biodegradable polyester that has gained popularity as a biomedical polymer due to its biocompatibility, ease of manipulation both chemically and physically, and tunable degradation rates. It is a versatile polymer that can be processed into various forms, including films, fibers, and 3D printed scaffolds, making it suitable for a wide range of applications in tissue engineering, and drug delivery. PCL is degraded by hydrolysis of its ester linkages under physiological conditions at a slower rate than other common biodegradable polymers such as polyglycolide (PGA), poly lactic acid (PLA), and their copolymers, thus making it useful for longer term implants.
