Self-assembly of Amphiphilic Graft Copolymer in Selective Solvent

The self-assembly of amphiphilic graft copolymer in different selective solvent was studied by coarse-grained molecular dynamics(CGMD) simulations.Influence of the rigidity of the backbone chain is mainly focused on.The results show that,when the solvent is good for the backbone while bad for the branches,flower micelle,flower-bridge micelle and bridge micelle can be obtained by increasing the rigidity of the backbone,when the solvent is bad for the backbone while good for the branches,core-shell structure with spherical or ellipsoidal shape,as well as the bunch structure,can be observed.Only the single core-shell structure can be obtained even for long chains in this selective solvent.

Self-Assembly of Amphiphilic Graft Copolymer with Poly(acrylic Acid) Backbone and N-Octylphenyl Poly(oxyethylene) Side Chains in Water

The self-assembly of the amphiphilic graft copolymer AA-C8PhEO10Ac in water was investigated by fluorescence technique using 8-anilino-1-naphthalene sulfonate(ANS) as a probe and transmission electron microscopy (TEM), the effects of inorganic salt , copolymer concentration and pH on the micellar size and structures of AA-C8PhEO10Ac were discussed. It was found that the micelle morphologies and sizes were related with the micellar preparation methods. The sizes of micelles increased with the addition of NaCl and decreased at high pH values.
