Graphical Abstract

On page 1905 (DOI: 10.1002/pola.27193), Haoyu Tang, Ying Ling, Yong Deng, and Donghui Zhang describe the preparation of a series of coil-rod poly(ethylene glycol)-b-poly(γ-benzyl-L-glutamate)s (PEG-b-PBLGs). FTIR analysis shows they adopt an α-helix in the solid state. S/WAXS analysis reveals a lamellar structure of the PEG-b-PBLGs where PBLG segments pack into hexagonal arrays when frod is less than 0.28. Incorporation of single-walled carbon nanotubes (SWCNTs) causes a d-spacing increase in both lamellar and hexagonal packing. This suggests that in the intercalation of SWCNTs into the PEG-b-PBLGs matrices, the SWCNTs are oriented normal to the lamellar interface.
