Effect of Molecular Modification on PCL Foam Formation and Morphology of PCL

Macromolecular Symposia, 2005
AbstractPoly(ϵ‐caprolactone) was chemically modified by using dicumyl peroxide from 0.25 to 2 % (w/w) and the effects of molecular architecture on the density and morphology of PCL foams were examined. The polymer was first blended with dicumyl peroxide at a low temperature (80°C), to prevent premature peroxide decomposition.

PCL and PCL/PLA scaffolds for bone tissue regeneration

2013
This paper investigates the use of PCL and PCL/PLA scaffolds, produced using a novel additive biomanufacturing system called BioCell Printing, for bone tissue engineering applications. Results show that the BioCell Printing system produces scaffolds with regular and reproducible architecture, presenting no toxicity and enhancing cell attachment and ...

Miscibility of TPU(PCL diol)/PCL Blend and Its Effect on PCL Crystallinity

Macromolecular Symposia, 2007
AbstractPoly(ε‐caprolactone) (PCL) was melt blended with thermoplastic polyurethane based on polycaprolactone diol (TPU(PCL diol)). The amount of PCL was varied from 20% to 50% by weight. A single composition dependent glass transition temperature (from DSC) shows the miscibility of system. Also the negative value of polymer‐polymer interaction density,

Construction of PCL-collagen@PCL@PCL-gelatin three-layer small diameter artificial vascular grafts by electrospinning

Biomedical Materials, 2022
Abstract The demand for artificial vascular grafts in clinical applications is increasing, and it is urgent to design a tissue-engineered vascular graft with good biocompatibility and sufficient mechanical strength. In this study, three-layer small diameter artificial vascular grafts were constructed by electrospinning. Polycaprolactone (

Water-responsive shape memory PLLA via incorporating PCL-(PMVS-s-PAA)-PCL-PTMG-PCL-(PMVS-s-PAA)-PCL

European Polymer Journal, 2021
Abstract Poly(L-lactide) (PLLA) was one of the most well-known biodegradable polyesters. Although its thermo-responsive shape memory (SM) function has been studied by proper program, high transformation temperature is not suitable in some biomedical applications.

Allografts in PCL Reconstructions

2013
Posterior cruciate ligament (PCL) injuries are often associated with other ligament lesions. Multiligament reconstructions require an important quantity of grafts and often determine the need for cadaver allografts during the surgical repair procedures.

The role of PCL reconstruction in knees with combined PCL and posterolateral corner deficiency

Knee Surgery, Sports Traumatology, Arthroscopy, 2007
AbstractAlthough many PCL injuries are in combination with posterolateral corner (PLC) injuries, there has been little work done on combined injury reconstruction; the literature includes differing recommendations. It was hypothesised that a double‐bundle PCL reconstruction would restore both posterior drawer and external rotation laxities closer to ...

A historical perspective of PCL bracing

Knee Surgery, Sports Traumatology, Arthroscopy, 2012
AbstractPurposeCurrently there are many functional knee braces but very few designed to treat the posterior cruciate ligament (PCL). No PCL braces have been biomechanically validated to demonstrate that they provide stability with proper force distribution to the PCL‐deficient knee.
