从图7d可以得知，原油粘度与温度存在一个负相关的关系。原油粘度在60

It can be seen from Figure 7d that there is a negative correlation between crude oil viscosity and temperature. The viscosity of crude oil drops to 0.02 (Pa·s) at 60 °C, which is only about 1/50 of that at 30 °C. Therefore, the light-heat effect of the oil-absorbing material will greatly increase the rate of crude oil absorption. It can be seen from Figures 7e and 7f that the absorption speed of crude oil droplets under light conditions at the same time differs greatly based on different absorption materials. CF has not absorbed it completely after 60 s. In contrast, CF-SA-PPy only takes 20 seconds to absorb crude oil. It can be seen that the photothermal conversion effect of the modified fabric effectively increases the temperature of the crude oil in contact with CF-SA-PPy, reduces the viscosity of the crude oil, increases the rate of adsorption of crude oil, and improves the efficiency of oil-water separation in practical applications. .

As can be seen from Figure 7d, there is a negative correlation between crude oil viscosity and temperature. The viscosity of crude oil drops to 0.02 (Pa.s) at 60 degrees C, which is only about 1/50 at 30 degrees C. Therefore, the photothermal effect of oil-absorbing materials will greatly improve the rate of crude oil absorption. As can be learned from Figures 7e and 7f, crude oil droplets at the same time under lighting conditions, based on the absorption speed of different absorption materials have a greater difference. CF absorbs more than 60 s and still does not fully absorb it. By contrast, CF-SA-PPy only needs 20s to absorb crude oil. It can be seen that the photothermal conversion effect of modified fabric effectively improves the temperature of crude oil in contact with CF-SA-PPy, reduces the viscosity of crude oil, improves the speed of adsorption of crude oil, and then improves the efficiency of oil and water separation in practical applications.

It can be seen from figure 7d that there is a negative correlation between crude oil viscosity and temperature. The viscosity of crude oil is 60 ° 02 (PA · s), only 30 ° About 1 / 50 of C. Therefore, the oil absorption material with photothermal effect will greatly improve the speed of crude oil absorption. It can be seen from figures 7e and 7F that the absorption speed of crude oil droplets under the condition of light at the same time is quite different based on different absorption materials. CF could not absorb it completely after more than 60 s. In contrast, it takes only 20 s for cf-sa-ppy to absorb crude oil. It can be seen that the photo thermal conversion effect of the modified fabric can effectively improve the temperature of crude oil in contact with cf-sa-ppy, reduce the viscosity of crude oil, improve the speed of adsorption of crude oil, and then improve the oil-water separation efficiency in practical application.<br>
