The self-assembly effect in NLO polymers containing isolation chromophores: enhanced NLO coefficient and stability
关键字：NLO polymers, isolation chromophores
In this paper, a facile route was designed to prepare four new NLO polyaryleneethynylenes, which were constructed by two different chromophore moieties with the regular AB structure, to achieve a high NLO coefficient according to our recent work on ‘‘isolation chromophores’’. Meanwhile, normal aromatic rings or perfluoroaromatic rings were also introduced as isolation groups to investigate t...

β-cyclodextrin and its hyperbranched polymers-induced micro/nanopatterns and tunable wettability on polymer surfaces
关键字：β-cyclodextrin,hyperbranched polymers,micro/nanopatterns
This paper reports an efficient strategy to fabricate micro/nanopatterns on the surfaces of polymers for obtaining tunable wettability. Tepee-like bundles as micro/nanopatterns, composed of irregular polygon ‘‘podium’’ and ‘‘valley’’ structures, are formed by adding b-cyclodextrin (b-CD) or its hyperbranched polymers [HBP(b-CD)s] into a polystyrene (...

Bulk versus fiber crystal structures of polymers and biopolymers
关键字：biopolymers, Bulk versus fiber crystal structures of polymers
Processing of crystalline polymers such as injection moulding or fibre spinning produces usually the mechanically more stable crystal modification of any polymer. Also, especially in fibre spinning, the chain axis is supposed to remain...

Intrinsic Self-healing of Covalent Polymers Based on Alkoxyamines Units
关键字：intrinsic self-healing, covalent polymers, alkoxyamines units
Cracks in intrinsic self-mending polymers can be healed as a result of crossover interconnection of reversible covalent bonds at the broken faces. Typical reversible covalent bonds served as basis for self-healing of ...
