Photochemically cross-linked poly(ε-caprolactone) with accelerated hydrolytic degradation

3D-printed poly-ε-caprolactone-CaCO3-biocomposite-scaffolds for hard tissue regeneration

“…In the literature values of 300 MPa are mentioned. In this context it is important to note that in this study relatively short chained PCL (45 000 kD) is used, which is characterized by a higher proportion of the crystalline material, what justifies the higher values in this study [32,33,37,38]. The modulus of the bulk materials increases up to 600 MPa at a concentration of 50% calcium carbonate.…”

“…This effect can be explained by the matrix-additiveinteraction, which increases with higher amounts of the additive and smaller particle size, due to higher specific surface. These interactions limit the movement of molecule chains and therefore increase the viscosity [30][31][32][33].…”

“…The crosslinked chains cannot reorient into crystalline regions and will decrease the mechanical properties of the material. Also the crosslinked chains will increase the degradation time [32,33,41,42]. Viana et al [43] showed that the high-energy gamma radiation has minor effects on calcium-carbonate.…”

Recent Progress in Isotropic Magnetorheological Elastomers and Their Properties: A Review

“…During processing, these radicals recombine with the present oxygen and cause an increased amount of carbonyl and hydroxyl groups in the oxidized TPE [ 143 ]. In FTIR spectra, a broad intensity peak appearing at around 3300 cm −1 presented the former group [ 144 ], whereas the absorption levels, varying at about 1650 cm −1 , were assigned to the later ones [ 145 ]. The minimum-oxygen-containing groups were observed in the original material; however, oxygen-containing groups increased as the TPE was subjected to reprocessing cycles (R0–R3).…”

Syntheses, characterization, and hydrolytic degradation of P(ε‐caprolactone‐co‐δ‐valerolactone) copolymers: Influence of molecular weight

“…A huge resurgence of interest during the 1990s and 2000s has propelled PCL back into the biomaterials. Introduction of functional groups into PCL, irradiation of doped PCL films, blends of copolymers, or copolymerization with co‐monomers with different architectures provide different strategies to tailor the PCL film properties thereby widening the range of their possible applications . It has been observed that co‐polymerization alters the chemical property that indirectly affects all others properties such as crystallinity, solubility, and degradation pattern resulting in a modified polymer with expanded properties for drug delivery …”
