Hierarchical Self-Assembly of Symmetric Supramolecular Double-Comb Diblock Copolymers
Abstract
<p>A double-comb diblock copolymer was constructed experimentally using a double supramolecular approach. Addition of 3-nonadecylphenol (3-NDP) amphiphiles to a symmetric, double hydrogen bond accepting poly(4-vinylpyridine)-<i>block</i>-poly(<i>N</i>-acryloylpiperidine) (P4VP-<i>b</i>-PAPI) diblock copolymer resulted in microphase separation on both the block copolymer and polymeramphiphile level. Variation of the comb density <i>x</i> in these [P4VP-<i>b</i>-PAPI](3-NDP)<i><sub>x</sub></i> supramolecular complexes gave rise to several unique hierarchical nanostructures. For high comb densities (<i>x</i> = 0.8 - 1.2) double perpendicular lamellae-<i>in</i>-lamellae were observed, while lowering the density to <i>x</i> = 0.5 resulted in a double parallel lamellar morphology as demonstrated by small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM). Further decreasing the concentration of 3-NDP (<i>x</i> = 0.3) caused the complex to self-assemble into cylinders-<i>in</i>-lamellae, while for <i>x</i> = 0.1 3-NDP only serves as a plasticizing agent. The phase transitions identified as a function of x are all in excellent agreement with our previously performed theoretical analysis.</p>
