Preparation and Morphology Characterization of Glucose-based/Maltose-based Macroporous Materials by High Internal Phase Emulsion Templating Method

Glucose/maltose-based monomers (G-GM/M-GM) were synthesized by the reaction of glucose/maltose with glycidyl methacrylate using potassium hydrate as the catalyst. FT-IR,1H NMR analysis confirmed the corresponding structures. Then the CO2-in-water high internal emulsions (HIPE, the internal phase fraction is more than 74.05%) were prepared by using G-GM/M-GM solution as the continuous phase, liquid CO2 as the dispersion phase, PVA-1788 as the surfactant. The results indicated that the HIPEs had sufficient stability, and could keep stable for more than 48 h. After the continuous phase was polymerized by ammonium peroxydisulfate/N,N,N',N'-tetramethylethylenediamine as the redox initiator system, the G-GM/M-GM-based macroporous materials were obtained. SEM analysis indicated that G-GM/M-GM-based materials had rich cell structure with open-cell morphology, and the average pore sizes were distributed in 10-25 μm. These structures endowed these mate-rials with the potentiality to be used in tissue engineering applications. © 2019, Materials Review Magazine. All right reserved.
