Web25 apr. 2005 · Hold on tight: The dynamics, rather than thermodynamics, of reversible cross-links are the primary determinants of bulk viscosities in a family of supramolecular networks. This result comes from a study in which a series of structurally similar pincer complexes (see picture, OTf=CF 3 SO 3 − ) that have different ligand-exchange … WebThermosets composed of cross-linked polymers demonstrate enhanced thermal, solvent, chemical, and dimensional stability as compared to their non-cross-linked counterparts. …
Web15 mar. 2012 · Cross‐linked organic materials or polymer networks have found numerous applications and technologies that are indispensable in everyday life. Networks formed via molecular recognition events that act as noncovalent cross‐linkers exhibit rather unusual properties due to the dynamic character and tunable strength of the supramolecular ...
WebA nanostructured thin film obtained from a polystyrene-block-poly(4-vinylpyridine) diblock copolymer was used as a template to produce Janus-type nanoparticles. This was achieved by functionalizing the poly(4-vinylpyridine) microdomains with a diene molecule and by cross-linking them with diiodo compounds. crash team racing hot air skywayWeb21 apr. 2014 · Cross-link density is an important parameter for the macroscopic mechanical properties of hydrogels. Increasing network density leads to an increase in the storage and loss moduli of the gel and can be accomplished by either increasing the concentration of cross-linkers, or by reducing the fraction of mechanically inactive cross-links. … diy with old booksWebUniversity Medical Center Groningen. jan. 2011 - jan. 20132 jaar 1 maand.
