Synthetic polymers have attracted much attention in tissue engineering due to their ability to modulate biomechanical properties. This study investigated the feasibility of processing poly(epsilon-caprolactone) (PCL) homopolymer, PCL-poly(ethylene glycol) (PEG) diblock, and PCL-PEG-PCL triblock copolymers into three-dimensional porous scaffolds ...

AbstractTo create new biofunctional materials, a polycaprolactone‐polysiloxane‐polycaprolactone (PCL‐PMVS‐PCL) carrying lactose was developed by ring‐opening polymerization and esterification reaction. 1H NMR and Fourier transform IR spectroscopy confirmed synthesis of the product.

Polycaprolactone microparticles and their biodegradation
Polymer Degradation and Stability, 2000Abstract Polycaprolactone (PCL) microparticles were prepared by an emulsification-solvent evaporation technique using various stabilizers such as gelatin, hydrophobically modified polyacrylamide derivative (PAM) and poly(vinyl alcohol) (PVA). It was shown that the particle size distribution of PCL microparticles was 13.4±4.7 (μm) in diameter with ...

Fungal degradation of polycaprolactones
Journal of Applied Polymer Science, 1983AbstractThree high molecular weight polycaprolactones (M̄w= 35,000, 18,600, and 7,130) were utilized as the sole carbon source by five of six fungi tested by the American Standards for Testing and Materials (ASTM) agar plate method. The fungi wereAspergillus flavus, A. niger, A.

Abstract Poly(e-caprolactone)–polydimethylsiloxane–poly(e-caprolactone) (PCL-PDMS-PCL) triblock copolymers with a wide range of block lengths (1000–32,000 g/mol) were synthesized by the ring-opening polymerization of e-caprolactone using aminopropyl terminated PDMS oligomers as the initiator. Reactions were carried out in bulk or solution at 125 ± 5 °

The product is a sterile, totally bioresorbable implant, whose principle components are polycaprolactone (PCL) microspheres suspended in a gel carrier of carboxymethyl cellulose. Microspheres have a size range of 25–50 μm, and it should be injected with a 27G needle or a 27G or 25G cannula.

DTA identification of polycaprolactone
Journal of Thermal Analysis, 1991Polycaprolactone (PCL) is a new material used in orthopedics. It is characterized by an endothermic melting peak at about 61‡C, an endothermic decomposition peak at about 380‡C and an exothermic peak at about 453‡C. These three observed phenomena and the corresponding thermodynamic data made it easily possible to identify PCL among the other polymers ...

Abstract Bioceramic or inorganic nanoparticles made of SiO2, TiO2, SrO, and hydroxyapatite (HAP) have been reported to improve cell adhesion onto polymers. However, direct mixing of these nanoparticles with polymers often leads to their aggregation within the polymer matrix and subsequent deterioration of the material’s mechanical strength.
