It can be seen from Tab.1 that G increased with the increase of GMA monomer concentration and reached the maximum value of 83.7%at the GMA mass fraction of 36%.This finding is consistent with literature[4].The existence of a large number of micro-porosities in sample 1#can help to uptake the grafting solution many times as its own weight during the immersing and padding process.The polymerization and radiation heats may change grafting into bulk polymerization,and all the monomers can be completely converted into the crosslinked polymers.The polymerization heat is unable to escape from the inside of the fabric due to the poor thermal conductivity,which is beneficial to the grafting.
