通过电子束诱导接枝聚合和开环反应制备了一种具有亲疏水微畴的两亲性聚丙烯非织造布，并将其用于邻苯二甲酸酯的吸附。为了说明这种两亲性微域的优越性，我们构建了一个不含亲水部分的独特结构作为比较。此外，还系统地研究了吸附动力学、等温线和pH效应等吸附行为。结果表明，两亲结构以及亲疏水微域之间的协同作用可以显著提高吸附能力、吸附速率和亲和力。特别是亲水性微畴的存在降低了吸附过程中的扩散阻力和能垒。这些吸附结果表明，两亲性PP非织造布具有环保应用的潜力。
A kind of amphiphilic polypropylene nonwoven with hydrophilic and hydrophobic microdomain was prepared through electron beam induced graft polymerization and subsequent ring opening reaction and then utilized in the adsorption of phthalic acid esters (PAEs). To elucidate the superiority of such amphiphilic microdomain, a unique structure without hydrophilic part was constructed as comparison. In addition, the adsorption behaviors including adsorption kinetics, isotherms and pH effect were systematically investigated. The result indicated that the amphiphilic structure and the synergy between hydrophilic and hydrophobic microdomain could considerably improve the adsorption capacities, rate and affinity. Particularly the existence of hydrophilic microdomain could reduce the diffusion resistance and energy barrier in the adsorption process. These adsorption results showed that the amphiphilic PP nonwoven have the potential to be used in environmental application.
