Drying and shrinkage of polymer gels
Brazilian Journal of Chemical Engineering
The polymer hydrogel was synthesized by photo-polymerization process (UV light, 60 O C) in presence of Photo-initiator (Irgacure R ) and Cross-linker (NN'-methylene bisacrylamide; MBAM). In the present work, the drying of polymer hydrogel was carried out to study the effect of temperature, gel-sheet thickness, monomer ratio of acryl acid to acrylamide (AA/AM), concentration of MBAM and quantity of monomers. A correlation has been developed for modified sheet thickness as a function ofdoi:10.1590/s0104-66322005000200007 fatcat:gwobn32l4fcj3pdv6opvngytiq
