synthesis and characterization of hydrogel nanocomposite polyacrylamide /halloysite nanotubes /chitosan for wound dressing

In this research, polyacrylamide/ halloysite nanoclay/ chitosan hydrogel nanocomposite were produced by the free radical polymerization. the obtained hydrogels were charactrised by scanning electron microscopy (sem), fourier transform infrared (ftir), thermal gravimetric analysis(tga). hydrogel wound dressings have many criteria of an ideal and advanced wound dressing. these bandages have the ability to absorb and retain a lot of water and drugs. therefore, hydrogel dressings are used for wounds with little discharge
