Thijssen, Quinten published the artcileFrom Chain Growth to Step Growth Polymerization of Photoreactive Poly-ε-Caprolactone: The Network Topology of Bioresorbable Networks as Tool in Tissue Engineering, Recommanded Product: Pentaerythritol tetra(3-mercaptopropionate), the main research area is photoreactive polycaprolactone step growth polymerization thermal mech biol property.
Control of the network topol. by selection of an appropriate crosslinking chem. is introduced as a new strategy to improve the elasticity and toughness of bioresorbable networks. The development of novel photocrosslinkable and bioresorbable oligomers is essential for the application of light-based 3D-printing techniques in the context of tissue engineering. Although light-based 3D-printing techniques are characterized by an increased resolution and manufacturing speed as compared to extrusion-based 3D-printing, their application remains limited. Via chem. modification, poly-ε-caprolactone (PCL) is functionalized with photoreactive end groups such as acrylates, alkenes, and alkynes. Based on these precursors, networks with different topologies are designed via chain growth polymerization, step growth polymerization, or a combination thereof. The influence of the network topol. and the concomitant crosslinking chem. on the thermal, mech., and biol. properties are elucidated together with their applicability in digital light processing (DLP). Photocrosslinkable PCL with an elongation at break of 736.3 ± 47% and an ultimate strength of 21.3 ± 0.8 MPa is realized, which is approx. tenfold higher compared to the current state-of-the-art. Finally, extremely elastic DLP-printed dog bones are developed which can fully retrieve their initial length upon stress relieve at an elongation of 1000%.
