Table 1 Molecular characteristics of worm-like PAA-b-PS diblock copolymers.
SamplesMn,PAA*Mn, PS*PDI†
Sample 19.6 K4.8 K1.19
Sample 211.1 K5.2 K1.16
Sample 36.8 K5.0 K1.15

*Molecular weight (Mn) of each arm was calculated from 1H NMR data.

†Polydispersity index (PDI) of PtBA-b-PS, the precursor of PAA-b-PS, was determined by GPC using polystyrene standards for calibration and THF as solvent. Samples 1 to 3 are the diblock copolymer templates for CdSe, Fe3O4, and BaTiO3, respectively.
