“…13 The introduction of aldehyde groups on the cellulose molecular chain makes dialdehyde cellulose easy to further functionalize. The dialdehyde cellulose composite materials can be obtained by Schiff base reaction, [14][15][16][17] cationization reaction, 18 and carboxylation reaction. 19 The composite materials have been increasingly applied in the field of analytical chemistry.…”

A novel high‐performance liquid chromatography (HPLC) multifunctional immobilized chiral stationary phase was prepared by bonding dialdehyde microcrystalline cellulose to aminosilica via Schiff base reaction and then derivatized with 3,5‐dimethylphenyl isocyanate. The HPLC multifunctional immobilized chiral stationary phase could not only achieve chiral separation but also achieve achiral separation. Chiral separation evaluation showed that 1‐(1‐naphthyl)ethanol and mandelonitrile got separation in normal phase (NP) mode. Ranolazine, benzoin ethyl ether, metalaxyl, and diclofop were successfully separated in reversed phase (RP) mode. Aromatic compounds such as polycyclic aromatic hydrocarbons (PAHs), anilines, and aromatic acids were selected as analytes to investigate the achiral separation performance of the multifunctional immobilized chiral stationary phase in NP and RP modes. The achiral separation evaluation showed that six PAHs could get good separation within 10 minutes in NP mode. Four aromatic acids were well separated in RP mode. The retention mechanism of aromatic compounds on the stationary phase was discussed, founding that π‐π interaction, π‐π electron‐donor‐acceptor (EDA) interaction, and hydrogen bonding interaction played important roles during the achiral separation process. This multifunctional immobilized chiral stationary phase had the advantages of simple bonding steps, short reaction time, and no need for space arm.

“…The high reactivity of the aldehyde groups makes the DAC easy to functionalize, especially through the Schiff base reaction with the amino reagent to prepare the DAC composites. [32][33][34][35] As a chiral selector, DAC has been applied as HPLC CSPs, which proves that DAC has both chiral and achiral separation ability. 36 Cyclodextrins are one of the most commonly used chiral selectors in HPLC for enantioseparation 37,38 due to their ability to form host-guest inclusion with a large variety of chiral compounds.…”

A novel biselector bonded‐type multifunctional chiral stationary phase (MCSP) was prepared by covalently crosslinking dialdehyde cellulose (DAC) with 6‐monodeoxy‐6‐monoamino‐β‐cyclodextrine (CD) via Schiff base reaction. The biselector bonded‐type MCSP had good chiral and achiral chromatographic performance in normal phase (NP) and reversed phase (RP) modes. Seven and eight enantiomers were successfully separated on the prepared biselector bonded‐type MCSP in NP and RP modes, respectively. The biselector bonded‐type MCSP showed enhanced chiral resolution ability compared with single selector chiral stationary phases due to the simultaneous introduction of DAC and 6‐monodeoxy‐6‐monoamino‐β‐CD on the surface of silica gel. Aromatic compounds including polycyclic aromatic hydrocarbons, anilines, phenols, phenylates, and aromatic acids were choosed as analytes to investigate the achiral chromatographic performance of the biselector bonded‐type MCSP in NP and RP modes. Chromatographic evaluation results showed that the above aromatic compounds were essentially capable of achieving baseline separation by hydrophobic interaction, π‐π interaction, and π‐π electron‐donor‐acceptor interaction. Moreover, the host‐guest inclusion effect of 6‐monodeoxy‐6‐monoamino‐β‐CD and the multiple interactions made the biselector bonded‐type MCSP have good steric selectivity. The preparation method of the biselector bonded‐type MCSP was simple and provided a new idea and strategy for the preparation of the subsequent novel biselector MCSP.

“…This could be attributed to the cross-linking reaction between CNC and GA via hydrogen bonding. [25][26][27] Besides, the crosslinking reaction between chitosan and glutaraldehyde could increase the activation energy due to the reduced chain mobility of cross-linked network and hence, higher amount of energy was required for cross-linking of the reactants. [28] Similar finding was reported by Correia et al [29] in which the activation energy was increased for cross-linked samples.…”

Cross‐linking of chitosan film composites was carried out by using conventional heating and microwave curing methods in this study. Non‐cross‐linked and glutaraldehyde (GA) cross‐linked neat chitosan and cellulose nanocrystals (CNC)/chitosan film composites were cured by either conventional oven heating or microwave irradiation. Tensile strength and Young's modulus of chitosan composites were enhanced significantly by the addition of CNC and GA especially for the microwave‐cured samples. The changes in chemical interaction of the chitosan film composites was determined by Fourier transform infrared (FTIR) spectroscopy. The microwave‐cured GA‐cross‐linked chitosan film composites were more thermally stable than non‐cross‐linked and conventionally heated GA‐cross‐linked chitosan film composites due to the formation of a more stable structure between GA and chitosan. Nevertheless, the reduced antimicrobial efficacy of film composites against Escherichia coli, Bacillus subtilis, and Saccharomyces cerevisiae was observed in cross‐linked film composites compared with non‐cross‐linked composites.
