3D printing of linear and three-arm star supramol. polymers with attached hydrogen bonds and their nanocomposites is reported. The concept is based on hydrogen-bonded supramol. polymers, known to form nano-sized micellar clusters. Printability is based on reversible thermal- and shear-induced dissociation of a supramol. polymer network, which generates stable and self-supported structures after printing, as checked via melt-rheol. and X-ray scattering. The linear and three-arm star poly(isobutylene)s PIB-B2 (Mn = 8500 g mol -1), PIB-B3 (Mn = 16 000 g mol -1), and linear poly(ethylene glycol)s PEG-B2 (Mn = 900 g mol-1, 8500 g mol -1) are prepared and then probed by melt-rheol. to adjust the viscosity to address the proper printing window. The supramol. PIB polymers show a rubber-like behavior and are able to form self-supported 3D printed objects at room temperature and below, reaching polymer strand diameters down to 200-300 μm. Nanocomposites of PIB-B2 with silica nanoparticles (12 nm, 5-15 wt%) are generated, in turn leading to an improvement of their shape persistence. A blend of the linear polymer PIB-B2 and the three-arm star polymer PIB-B3 (ratio ≈ 3/1 mol) reaches an even higher structural stability, able to build free-standing structures. In addition to this study using Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine, there are many other studies that have used Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Category: triazoles) was used in this study.
Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8) is a polytriazolylamine ligand which stabilizes Cu(I) towards disproportionation and oxidation thus enhancing its catalytic effect in the azide-acetylene cycloaddition.Category: triazoles
