Switching Supramolecular Polymeric Materials with Multiple Length Scales

Hybrid Supramolecular and Colloidal Hydrogels that Bridge Multiple Length Scales†

Hybrid nanocomposites were constructed based on colloidal nanofibrillar hydrogels with interpenetrating supramolecular hydrogels, displaying enhanced rheological yield strain and a synergistic improvement in storage modulus. The supramolecular hydrogel consists of naphthyl-functionalized hydroxyethyl cellulose and a cationic polystyrene derivative decorated with methylviologen moieties, physica...

Self-Organization on Multiple Length Scales in "Hairy Rod"-Coil Block Copolymer Supramolecular Complexes

The last two decades have seen an explosion of research activity in the area of self-assembled polymeric and supramolecular materials. Self-assembly schemes rely on an often delicate balance between competing repulsive and attractive forces between structural elements. In traditional coil-coil block copolymers, microphase separated structures are dictated by the balance of immiscibility between...

Supramolecular Interfacial Polymerization: A Controllable Method of Fabricating Supramolecular Polymeric Materials

A new method of supramolecular polymerization at the water-oil interface is developed. As a demonstration, an oil-soluble supramonomer containing two thiol end groups linked by two ureidopyrimidinone units and a water-soluble monomer bearing two maleimide end groups are employed. Supramolecular interfacial polymerization can be implemented by a thiol-maleimide click reaction at the water-chloro...

Investigation on the Achievable Flow Length in Injection Moulding of Polymeric Materials with Dynamic Mould Tempering

A variety of parts in microsystems technology are manufactured by injection moulding of polymeric materials. In Particular the high cooling velocity affects negatively the process and the resulting part properties. The scope of this paper is to investigate the influence on the reachable flow length in injection moulding of different polymeric materials. The results indicate that the mould tempe...
