Surfactant Mediated Microphase Separation in Miscible Block Copolymer of Poly(4-vinyl pyridine-b-hydroxybutylacrylate)
Based on the disordered miscible block copolymer P4VP-b-P4HBA
we constructed the ordered microphase separation structure via blending with amphiphilic surfactants. Through the noncovalent interaction between P4VP and different amphiphilic molecules. ordered microstructures were obtained
giving rise to a new perspective for the fabrication of hierarchical nanostructures and nanomaterials from miscible block copolymers.
Abstract
Miscible disordered block copolymers (BCPs) are rarely studied due to the limits in self-assembly into ordered microstructures. Herein
we proposed a facile method for the transformation of disordered miscible BCPs to comb-like BCPs with well-ordered microphase separation structures
via
blending with amphiphilic surfactants. In this work
poly(4-vinyl pyridine-
b
-hydroxybutylacrylate) (P4VP-
b
-P4HBA) was applied as a model of miscible disordered BCPs and the microphase separation was induced
via
blending with surfactants of dodecylbenzene sulfonic acid (DBSA) and 3-pentadecylphenol (PDP). The ordered microstructures including spherical and cylindrical morphologies were confirmed by transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS) investigation. These ordered microstructures thermal sensitive
in which ordered and disordered transformation (ODT) was observed in the blend of P4VP-
b
-P4HBA and PDP whereas it disappeared in the blend of P4VP-
b
-P4HBA and DBSA. The results show that the thermal stability of the ordered microstructures are strongly depends on the interactions between the miscible BCPs and surfactants
which investigated by
in situ
SAXS and Fourier transform infrared spectrometer (FTIR). The combination of miscible BCPs and surfactant creates a feasible strategy to fabricate ordered nanostructures
which could be employed to develop complicated nanomaterials.
