Performance test:
Zeta potential test: surface of solids Zeta potential analyzer (SurPASS3) test comparison example 1 and embodiment are used
The Zeta potential on the surface epoxy coating F0, F1, F2, F3 obtained by 1-3.The results are shown in Table 1.
Table 1
| Epoxy coating | F0 | F1 | F2 | F3 |
| Zeta potential (mV) | -33.7262 | -0.0145 | -27.0029 | 2.0013 |
By table 1, it can be seen that, the Zeta potential of F1, F2, F3 are significantly larger than F0, and with coating surface quaternary ammonium salinity
Increase, film surface current potential tends to positive potential, this is because F1, F2, F3 coating surface are all covered with positively charged quaternary ammonium salt,
Therefore provable F1, F2, F3 coating is successfully introduced into quaternary ammonium salt.
Contact angle test: using contact angle tester (JC 20CODI) test water on the surface epoxy coating F0, F1, F2, F3
Contact angle.The results are shown in Table 2.
Table 2
| Epoxy coating | F0 | F1 | F2 | F3 |
| Contact angle (°) | 113.7 | 113.2 | 111.4 | 114.4 |
As can be seen from Table 2, contact angle of the water on the surface coating F0, F1, F2, F3 does not have notable difference, illustrates certain
Under concentration range, the addition of quaternary ammonium salt does not influence the hydrophilic and hydrophobic of coating significantly.
Stability test: stability test is carried out to F0, F1, F2, F3, F4 coating sample.Steps are as follows: samples weighing
(m0) after sample is soaked in 4 week in water, then take out weighing after sample filter paper removes the water on surface and obtain the flat of sample
Weighing apparatus swelling quality ms；Then it is dried under vacuum to constant weight mf, percent swell Ws (%) and mass loss ratio W1The calculating of (%)
It is as follows:
The results are shown in Table 3.
Table 3
| Epoxy coating | F0 | F1 | F2 | F3 | F4 |
| Percent swell Ws (%) | 9.1 | 10.1 | 9.4 | 10.8 | 14.2 |
| Mass loss ratio W1(%) | 1.3 | 0.5 | 0.4 | 0.7 | 7.3 |
The percent swell of F1, F2, F3 and F0 contrast difference are little, and the swelling of sample is mainly related with hydrophilic and hydrophobic, this
Data are consistent with the result of contact angle test, in addition, the swelling problem of F4 is more obvious, illustrate quaternary ammonium salt is excessively added meeting
Influence the hydrophilic and hydrophobic of epoxy coating.For the mass loss ratio of sample, compared with F0, after impregnating for 4 week in water,
F1, F2, F3 only have a small amount of mass loss, illustrate coating stable；The mass loss of F4 is more (> 5.0%), illustrates that F4 coating is unstable
It is fixed.This shows that in a certain range the addition of quaternary ammonium salt does not influence the stability of coating；Once it goes beyond the scope, quaternary ammonium salt
Be excessively added and can destroy coating structure so that coating is easy to fall off in water, be not available.
Chlorella adhesion experiment: the sample of coating F0, F1, F5, F6, F7 are respectively placed in 24 orifice plates, ultraviolet sterilization
Then 2mL chlorella algae solution (concentration: 10 is added in 30min7Cell/mL), 24 orifice plates are set in the light incubator in 25 ± 1
DEG C, 12h daytime: 12h night, illumination be 4800LUX under conditions of cultivate 5 days.Sample is taken out to 24 new orifice plates, 2mL PBS is added
Solution is placed in shaking table, and 10min, the sample laser confocal scanning microscope of taking-up are rocked under conditions of 150rpm
(CLSM) it is observed, CLSM result is as shown in Figure 1 to Figure 3.
By CLSM analysis as can be seen that F0 surface adhesion more chlorella, F5, F6, F7 surface adhesion have on a small quantity
Chlorella, and the surface F1 illustrates compared with F0 almost without frustule, F1, F5, F6, F7 significantly can inhibit chlorella to exist
The growth and adherency on its surface have good antifouling property, and compared with F5, F6, F7, the effect of algae restraint of F1 is more preferable.
It is understood that being merely to illustrate the present invention above with respect to specific descriptions of the invention and being not limited to this
Technical solution described in inventive embodiments.Those skilled in the art should understand that still can be carried out to the present invention
Modification or equivalent replacement, to reach identical technical effect；As long as meet use needs, all protection scope of the present invention it
It is interior.
