FAQs
What is Polycaprolactone?
Polycaprolactone (PCL) is a synthetic polymer synthesized through the ring-opening polymerization of ε-caprolactone monomer. It is a linear, semicrystalline polymer with excellent biocompatibility, processability, and biodegradability. PCL has widespread applications in various fields, particularly in drug delivery, tissue engineering, and environmental protection. Due to its low melting point and good mechanical properties, PCL is commonly used to prepare microspheres, scaffolds, and films.
Is Polycaprolactone Biodegradable?
Yes, Polycaprolactone (PCL) is biodegradable. Its degradation process mainly occurs through hydrolysis, with the resulting products eventually broken down by microorganisms into harmless substances. Because PCL degrades slowly, typically over several months to years, it is considered an environmentally friendly material and is widely used in fields such as biomedicine, packaging, and agriculture.
