Preparation and evaluation of poly (1-allyl-3-methylimidazole chloride@1,6-hexanediol dimethacrylate) conventional size monolithic column for HPLC

A combined experimental and molecular dynamics simulation study on customizing surface chemistry of graphene oxide toward high‐performance natural rubber composites

“…The peak at 3142 cm −1 was associated with C–H stretching vibrations (C(4)–H and C(5)–H of AMI in supporting information, Fig. S1), while the peak at 3078 cm −1 was related to the C(2)–H stretching vibration along with the intermolecular hydrogen bonds (C–H⋯Cl − ) formed between aromatic C(2)–H and ionic Cl − 25 . After mixing with GO, the peaks at 3142 and 3078 cm −1 of AMI shifted to 3156 and 3103 cm −1 , respectively.…”

“…S1), while the peak at 3078 cm −1 was related to the C(2)-H stretching vibration along with the intermolecular hydrogen bonds (C-HÁ Á ÁCl − ) formed between aromatic C(2)-H and ionic Cl − . 25 After mixing with GO, the peaks at 3142 and 3078 cm −1 of AMI shifted to 3156 and 3103 cm −1 , respectively. The blue-shifted frequency of the C-H stretching vibration of the imidazolium ring suggested that the intermolecular hydrogen bond in AMI was weakened by the newly formed hydrogen bond between Cl and the hydroxyl groups on the surface of GO.…”
