Effect of the hydrogen bond on stabilization of the intramolecular structure of comb-like polymers with amide groups in the side chain

In-plane oriented highly ordered lamellar structure formation of poly(N-dodecylacrylamide) induced by humid annealing

“…Usually, long-range lamellar ordering in comb-like polymers is ascribed to crystallization of the long alkyl side chains. 9,23 However, from the GI-XRD results, the dodecyl side chains in the in-plane oriented pDDA lamellar lm are in an amorphous state. Therefore, the formation mechanism of the highly ordered in-plane oriented lamellar pDDA lm greatly differs from that in semicrystalline comb-like polymers.…”
