Characterization and performance test are carried out to membrane sample obtained below.
Fig. 1 is the infrared spectrum for the AN-St-AMPS copolymers that the membrane sample PAN and embodiment 1-4 of comparative example 1 are obtained, from
Fig. 2 can be seen that for pure PAN, 2240cm-1The spike at place is the stretching vibration peak of three keys of-CN；AN-St-AMPS is copolymerized
Object, wave number 1650cm-1It is the stretching vibration peak of-C=O in amide group, 1550cm-1Bending vibration for-NH- and C-N
Stretching vibration, 1100cm-1The peak at place belongs to the symmetrical stretching vibration for O=S=O, illustrates the success on polymer molecular chain
Introduce sulfonic acid group.Positioned at 760cm-1And 700cm-1The strong face external extension for being absorbed as proton on 5 adjacent carbons of phenyl ring at place shakes
It is dynamic, the above result shows that PAN and AN-St-AMPS copolymers are successfully prepared.
Fig. 2 is that the water absorption rate for the AN-St-AMPS that the membrane sample PAN that comparative example 1 obtains and embodiment 1-4 are prepared is bent
Line chart.Water absorption rate has extremely important influence to the proton conductivity of proton exchange membrane, and according to proton transfer mechanisms, film is dry
It is almost nonconducting under state, proton only could be preferably transmitted under aqueous conditions, to discuss the introducing of AMPS to AN-
The influence of St-AMPS film water absorption rates, we test the water absorption rate of the film of difference AMPS contents under different soaking times.From figure
As can be seen that as soaking time extends, water absorption rate gradually rises, and identical in soaking time, with AMPS
Content increases, and water absorption rate is also continuously increased, this is because AMPS is a kind of water-soluble monomer, containing hydrophilic sulfonic acid group,
AMPS contents, which increase, can be such that sulfonic acid group quantity increases, and film is made to have good water imbibition, when AMPS contents are 50wt%, immersion
When time is 12h, the water absorption rate of film can reach 42% or so.
Fig. 3 is that the AN-St-AMPS that is prepared of the membrane sample PAN that comparative example 1 obtains and embodiment 1-4 impregnates after 12h not
With the swelling ratio of content AMPS films, swelling ratio size reflects the dimensional stability of film, and swelling ratio is higher to cause film-strength to be deteriorated.
Theoretically, swelling ratio is low preferably.As AMPS contents increase, the swelling ratio of AN-St-AMPS films can increase.This is because whole
In a proton exchange film system, AMPS contains sulfonic acid group, has stronger water absorbing capacity.As AMPS contents increase, absorb
Moisture increase, cause the swelling ratio of proton exchange membrane to increase.When AMPS contents reach 50wt%, the swelling of proton exchange membrane
Rate reaches 8.64%, it was demonstrated that the dimensional stability of film is good.
Fig. 4 is the ion exchange capacity figure for the AN-St-AMPS proton exchange membrane that embodiment 1-4 is prepared, and IEC values are anti-
What is reflected is the quantity containing sulfonic acid group in film, and IEC values are bigger, it is meant that the sulfonic acid group quantity of proton exchange membrane is more,
It connects and illustrates that the proton conductivity of film is bigger.From curve it can be seen that as AMPS contents increase, the ion of proton exchange membrane is handed over
Transducing power gradually increases, this is because sulfonic acid group number increases, can form more mutually continuous hydrophilic phase regions, be conducive to
The enhancing of ion-exchange capacity.When AMPS contents are 50wt%, the IEC of proton exchange membrane reaches 1.92mmol/g.
Fig. 5 is that the AN-St-AMPS membrane samples that the membrane sample PAN that comparative example 1 obtains is prepared with embodiment 1-4 are different
At a temperature of proton conductivity figure.It can be found that the proton conductivity of all films is improved with the raising of temperature.This be by
It is increased in temperature, molecular chain movement is accelerated, and free volume increases in film, and proton transmitting channel increases.Temperature increases simultaneously, moisture
The transmission rate of son and proton hydrate improves, and therefore, proton conductivity is improved with temperature rise.Under temperature the same terms, with
The increase of AMPS contents, the number of sulfonate radical increases, is easy to form continuous proton transmitting channel, is conducive to the transmission of proton,
Thus proton conductivity can dramatically increase.When 80 DEG C, when AMPS contents are 50wt%, since which create more H+It is higher
Water absorption rate, the proton conductivity of film reaches 1.35mS/cm, compared with pure PAN films, improve five orders of magnitude.
The membrane sample PAN that comparative example 1 obtains and the AN-St-AMPS films that embodiment 1-4 is prepared are subjected to mechanical performance
Test, the results are shown in Table 1.
Table 1
As it can be seen from table 1 the film prepared by us has more excellent intensity, as AMPS contents increase, proton
The tensile property of exchange membrane is in the trend being gradually reduced.When wherein AMPS contents are 20wt%, the stretching of AN-St-AMPS films is strong
Degree and stretch modulus are best, and tensile strength reaches 31.79MPa, and purer PAN film-strengths are declined, but remain to meet fuel electricity
Performance requirement of the pond to proton exchange membrane.
