Specific embodiment
The utility model is further described with reference to embodiments.
Embodiment 1
Full fluorin proton exchange film notacoria described in the utility model, referring to Fig. 1, including PET polyester film substrate layer 1,
Active layer 2 and grafting layer 3, grafting layer 3, active layer 2 and PET polyester film substrate layer 1 are successively set in accordance with the order from top to bottom
It sets, the upper surface of grafting layer 3 is bonded fuel cell membranes 4.
The thickness of PET polyester film substrate layer 1 is between 50-200 μm.
Active layer 2 be passed through by using plasma treatment instrument activated gas it is modified to PET polyester film substrate layer 1 and
At.
Activated gas is Ar2.Activated gas pressure used in the utility model is 20-90Pa, by increasing pressure, pressure
When big, gas concentration is big, and the active particle number of generation increases, but in accelerator, collision probability increases active particle simultaneously
Greatly, particle inactivation probability increases, so keeping PET polyester film surface contact angle maximum there are an optimal conditions.This is practical new
Activated gas power used in type is 60-140W, changes power, and power hour, activated species number is few, and graft numbers are few,
Contact angle variation is small, and as power increases, graft numbers are gradually increased, and contact angle becomes larger, and after reaching certain power, continues
Increase power, group falls off from polymer surfaces decomposition, and contact angle is caused to become smaller.
Grafting layer 3 is to be passed through grafting gas by using plasma treatment instrument to form the modification of active layer 2, grafting layer 3
Thickness is between 1-50nm.
Being grafted grafting time used in layer 3 is 5-20min, handles the incipient stage, grafting rate is gradually increased, with the time
Extension, grafting amount continues to increase, while more and more active particles can have an effect with the group of grafting, causes group de-
It falls, when being grafted suitable with exfoliation rates, is at a kind of equilibrium state, treatment effect is made to tend towards stability.Used in the present embodiment 1
Grafting power is 90-190W, and frequency is high, and ion concentration is high, and single ion energy is small, and process uniformity is good, but the excessively high meeting of frequency
Concentrate material surface energy excessively, if material surface is too thin to perforate, frequency is low, and ion concentration is low, single ion
Concentration is high, and process uniformity is more weaker.
