This work describes the fabrication, characterization, and properties of a novel hybrid poly(ethylene glycol) (PEG)-based hydrogels via in situ polymerization.The hybrid hydrogels were fabricated by free-radical redox polymerization using ammonium persulfate (APS), N,N,N,N-tetramethylethylenediamine (TEMED) as initiators and N,N-methylenebisacrylamide (BIS) as cross-linker at 60 ℃.To create a hybrid hydrogel, 0.2 wt % of MgAl LDH was added to the aqueous solution by ultrasonic dispersion.The physicochemical properties of hybrid hydrogels under vacuum freeze-drying processing were characterized by FT IR, TGA, SEM, while swelling kinetics and gel content were calculated.These studies indicated swelling degree in distilled water was varied from 94-125% with a gel content of 83-91%.SEM images showed the micron pore size of hydrogels could be adjusted within the range of several micrometers by changing the cross-linker content from 2% o m 2%-s showedd with roved the phsical to 10%.The results showed that the hybrid hydrogels exhibited excellent physicochemical behavior and might be a promising material for applications in tissue engineering and drug delivery.
