Polyether modified polysiloxane defoaming agents which was prepared by using hydrogenous polysiloxane and polyether as startintg materials, has good properties. 在聚硅氧烷鏈段上引入聚醚鏈段而得到的聚醚改性聚硅氧烷消泡劑是一種性能優良的消泡劑。
It was shown that the modified membranes with higher grafting rate expressed better anti-fouling ability in the ultrafiltration of protein solutions. 實驗結果表明，隨著接枝率的提高，改性聚碸膜抗蛋白質吸附污染的能力顯著增強。
