聚四氟乙烯(以下简称F

)具有优良的机械性能和热稳定性及化学稳定性,以它为基材而制得的离子交换膜具有较理想的性能。由于F

耐氧化,不为任何已知的溶剂溶胀,若采用热化学法来实现F

接枝改性是十分困难的,因此,F

辐射接枝改性是一个极为有效的途径。
Acrylic acid was grafted onto a 0.02~0.03mm thick polytetrafluoroethylene (PTFE)film by irradiation. The effect of monomer concentration
dose
dose rate and temperature on the grafting was investigated. The results suggested that the rate of graft polymerization increased with the monomer concentration. Specific electric resistance of the grafted film
dimensional changes
water absorption were dependent only on the grafted amount
but not on the irradiation conditions. The relationship between the specific electric resistance and the grafted amount of the grafted film was calculated by empiric formula: PG
1.2696
=2857 where
P is the specific electric resistance and G is the percentage of grafted amount. At a higher dose rate
the kinetic curves show a self-acceleration. At a lower dose rate
the kinetic curves tend to saturation
with no critical irradiation intensity.
