Efficient Functionalization of Additives at Supramolecular Material Surfaces

Abstract: Selective surface modification reactions can be performed on additives that are supramolecularly incorporated into supramolecular materials. Hereby, processing of the material, that regularly requires harsh processing conditions (i.e., the use of organic solvents and/or high temperatures), and functionalization can be decoupled. Moreover, high-resolution depth profiling by time-of-flight (ToF) secondary-ion mass spectrometry clearly shows distinct differences in surface and bulk material composition.

“…This would of course hold true for any material system that is developed on simple 2D substrates and later further processed into more complex 3D structures. However, since the increase in required additive is only five times, it could be hypothesized that a certain gradient of additive concentration is present from the bulk to the surface of the material, as was seen before in another supramolecular functionalization study . If this gradient is present, the cross‐sectional shape and surface area would influence this gradient, which is different for one solid layer and a thin electrospun fiber.…”

“…This result indicates that UPy-Tz is enhanced at the surface of the material. 39 A decrease in the nitrogen content is observed after the modification of the surface with bi-functional-PEG-BCN (4) and star-PEG-BCN (5) (4.8 atom% and 5.1 atom%, respectively) compared to the bare PCLdiUPy surface (5.5 atom%). An increase of fluorine to 0.2 atom% was detected after surface modification with the hydrophilic PEG polymers, which could be an effect of the incubation in aqueous medium that results from the rearrangement of UPy-Tz at the supramolecular material surface.…”

“…An increase of fluorine to 0.2 atom% was detected after surface modification with the hydrophilic PEG polymers, which could be an effect of the incubation in aqueous medium that results from the rearrangement of UPy-Tz at the supramolecular material surface. 39 The wettability of the modified surfaces was investigated by static water contact angle measurements. No major changes were observed for the bare PCLdiUPy surface and the PCLdiUPy surface after incubation with the mono-functional-PEG-BCN (3), bi-functional-PEG-BCN (4) and star-PEG-BCN (5) (Fig.…”

“…Previously, supramolecular polymers based on bisurea (BU) and 2-ureido-4[1H]-pyrimidinone (UPy)-modified supramolecular polymers were used to develop electrospun microporous vascular grafts that finally are proposed to be biocompatible and fully resorbable (Figure 1A;Van Almen et al, 2016;Kluin et al, 2017;van Haaften et al, 2017;Ippel et al, 2019;van Haaften et al, 2019). These supramolecular polymers have been identified as promising candidates to synthetically mimic the complexity of extracellular matrix (Goor et al, 2017;Diba et al, 2018). Due to their reversible and adaptable nature, the supramolecular materials possess extraordinary mechanical, tunable, responsive and processable properties which cannot be achieved with conventional macromolecules (Aida et al, 2012).…”
