Table 1 shows the mass ratios of the resin/vinyl silicone oil-modified resin to triclosan in examples 1-6 step (2)
Experimental example 1
The resin coatings prepared in examples 1-5 were subjected to a water slip angle test.
The experimental results show that:
as shown in FIG. 1, the increase in triclosan content has little effect on the liquid blocking resistance. This is because no silicone oil is added, and no micro-nano structure with low surface energy is formed on the surface of the resin coating, so that the anti-adhesion performance is not greatly different.
Experimental example 2
The resin coatings prepared in examples 3 and 6 were subjected to a water sliding angle test.
The experimental results show that:
as shown in fig. 2, the resin coating with silicone oil has a significantly smaller sliding angle to water than the non-silicone oil resin coating in example 3, which shows that the silicone oil segment in the resin coating in example 6 acts to form a micro-nano structure with low surface energy, thereby achieving the effect of waterproof adhesion.
Experimental example 3
An antibacterial test was performed on the resin coatings prepared in examples 1 to 5. First, 0.5mL of E.coli bacterial liquid (bacterial liquid concentration: 10) was added to the resin coating (1 cm. Times.1 cm) and 1 blank glass substrate prepared in examples 1 to 5, respectively 7 and/mL) and then inoculated in a tube with 4.5mL of PBS solution for 12h. After the culture is completed, 500uL of the cultured liquid is diluted and shaken uniformly in 4.5mL of PBS solution, 100uL of the diluted liquid is taken in an agar culture medium, and the agar culture medium is uniformly coated by a coating rod. Finally, placing the culture dish into a constant temperature incubator at 37 ℃ for culturing for 14 hours, observing the phenomenon of the culture dish, and taking a picture.
The experimental results show that:
as shown in fig. 3, the blank glass substrate and the resin coating without triclosan had no remarkable antibacterial effect, but the more triclosan was added, the better the antibacterial effect, but when the triclosan content was too much, the film forming property was poor. Thus, example 3 (resin: triclosan=2:1) was selected for further anti-bacterial adhesion experiments herein.
Experimental example 4
The resin coating prepared in example 3 was subjected to a mildew-proof experiment. The Aspergillus niger liquid was first diluted, then placed in a spray bottle, PDA medium (potato dextrose agar medium) was prepared and poured into a plate. 100uL of the resin coating solution prepared in example 3 was taken in a petri dish and uniformly coated with a coating rod. Finally, placing the culture dish into a constant temperature incubator at 28 ℃ for 7 days, observing the phenomenon of the culture dish, and taking a picture.
The experimental results show that:
as shown in FIG. 4, the black flocked colonies of the blank group are obviously more than those of the experimental group by comparison of the growth conditions of Aspergillus niger, which shows that the resin coating added with triclosan has good mildew-proof effect.
Experimental example 5
The resin coatings prepared in examples 3 and 6 were subjected to an anti-bacterial adhesion test. First, 0.5mL of E.coli bacterial liquid (bacterial liquid concentration: 10) was added to each of the resin coating layers (1 cm. Times.1 cm) and 1 blank glass substrate prepared in example 3 and example 6 6 and/mL) and then inoculated in a tube with 4.5mL of PBS solution for 4h. After the incubation was completed, the glass sheet was removed using forceps, rinsed with an appropriate amount of PBS buffer, then placed into a tube containing PBS buffer, and sonicated for 3min. 100uL of the sonicated liquid was placed in agar medium and uniformly spread with a spreading bar. Finally, placing the culture dish into a constant temperature incubator at 37 ℃ for culturing for 14 hours, observing the phenomenon of the culture dish, and taking a picture.
The experimental results show that:
as shown in fig. 5, it can be seen from comparison that the experimental group in which the vinyl silicone oil was added in example 6 has a smaller relative colony count than that of the blank glass substrate, indicating that the low surface energy antibacterial resin coating has a good antibacterial adhesion effect due to the low surface energy of the substrate surface, and bacteria are difficult to grow on the coating surface, thereby reducing adhesion of bacteria.
The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, and yet fall within the scope of the invention.
