两亲性分子在HDPE表面的包埋及持久的亲水改性
Hydrophilic improvement and water immersion durability of the HDPE surface by the entrapping with the amphiphilic modifier
摘要
Abstract
An entrapping modification was carried out on the high?density polyethylene ( HDPE) surface by applying the poly ( ethylene oxide ) monooleate ( OEO?5 ) modifier and introducing 2, 2′?azobisisobutyronitrile( AIBN) initiator into the swollen HDPE surface. By X?ray diffraction ( XRD) and scanning electron microscopy ( SEM) ,a swelling layer was proved to locate in the amorphous region on the swollen HDPE surface,from which the modifier could penetrate into the surface. Therefore,a higher swelling degree would facilitate modifier entrapment into the surface. The lowest contact angle of 15. 3° was reached on the surface based on the highest swelling degree of 16. 3%. Benefiting from introduction of AIBN and the double bond of OEO?5,excellent water immersion durability was exhibited on the modified surface with a lower contact angle of 47. 0° even after 5 weeks of water contact.关键词
