超疏水聚氨酯泡沫具有吸附剂的潜力,基于此,以生物质来源的木质素为原料,通过液化得到多元醇,并在合成过程中引入氟化碳化硅(F-SiC)和聚磷酸铵(APP),制备出一种木质素基超疏水聚氨酯泡沫。结果表明:随着F-SiC和APP的加入,所得泡沫的水接触角可达151.6°,表现出优异的疏水特性。此外,该聚氨酯泡沫在机械稳定性、油水分离性能、可降解性和阻燃性能方面均有出色表现,为其在原油吸附及相关应用领域的进一步开发提供了良好的基础。
Superhydrophobic polyurethane foam has the potential as an adsorbent.This study used lignin,a biomass-derived material,as a raw material to obtain polyols through liquefaction.Fluorinated silicon carbide(F-SiC) and ammonium polyphosphate (APP) were incorporated during the synthesis process,successfully preparing a lignin-based superhydrophobic polyurethane foam.The results showed that with the addition of F-SiC and APP,the water contact angle of the foam reached 151.6°,demonstrating excellent hydrophobic properties.Furthermore,the polyurethane foam exhibited outstanding mechanical stability,oil-water separation performance,biodegradability,and flame retardancy,providing a strong foundation for further development in crude oil adsorption and related applications.
