Crystal melting and its kinetics on poly(ethylene oxide) by in situ atomic force microscopy

Linear Terpyridine‐Ruthenium(II) Poly(ethylene glycol) Coordination Polymers

“…The ordering is most probably caused by the poly(ethylene glycol) chain folding. [25] To confirm this assumption, a covalent poly(ethylene glycol) (M n of 100 000 Da) was investigated using similar preparation conditions. In this case, a lamellar morphology was also observed (Figure 7, right) with a similar periodicity (20 nm).…”

Moisture-Induced Surface Crystallization of Spray-Dried Amorphous Lactose Particles Studied by Atomic Force Microscopy

“…The literature on the use of AFM for the quantification of crystallization processes is limited. Trojak and coworkers reported that the surface roughness increased significantly as a film of amorphous felodipine crystallized,14 and Beekmans and coworkers used AFM to study the kinetics of crystal melting of poly(ethylene oxide) 19…”

Branched Crystalline Patterns Formed Around Poly(ethylene oxide) Dots in Humidity

“…But, in an ultrathin or thin film, a constrained geometry system, the properties of polymer chains, such as crystallinity, chain packing and orientation, are different from the bulk state. Atomic force microscopy (AFM) studies of thin polymer films have visualized the growth [1][2][3][4][5][6][7][8] and melting [7,9] of crystalline lamellae in spherulites and the lamellar growth in shishkebab structures, [10,11] and also given rise to some controversial topics in the field of existing polymer crystallization theories. [3] Branched crystalline patterns different from spherulite have been observed in ultrathin polymer films.…”
