Chain-folding polydiimide

F. 9 Structures of the chain-folding polydiimide (5) and pyienyl-terminated PDMS (6) synthesized by Colquhoun, Hayes and co-workers... 

Fig. 22 Proposed cross-linked network produced through D-A interactions resulting from addition of P-AuNPs to the chain-folding polydiimide 5...

To improve the mechanical properties of the nanoparticle-containing nanocomposite, a novel three-component blend was designed (Fig. 23) [87]. These materials contained P-AuNPs, a pyrenyl-containing polymer 7 (Fig. 12) and the chain-folding polydiimide 8. 

Scheme 3 Proposed healing mechanism for the supramolecular polymer blend comprising a chain-folding polydiimide (7, in blue) and bis-pyrenyl-end-capped polysiloxane (8, in red). See Figure 14. (Reproduced with permission from Ref. 32. Royal Society of Chemistry, 2009.)...
