EPDM Ultrafine Fiber and Oil Sorption Application Thereof
The EPDM ultrafme fiber (EUF) was prepared by electrospun for oil sorption application. Through microwave radiation, the unsaturated side-chain of EPDM formed a crosslinking tri-dimensional network structure, which greatly improved physical properties. Infrared (IR) spectra were used to study the structure of EUF both before and after crosslink. The morphology of EUF was investigated by scanning electron microscopy (SEM). The oil swelling process of the gel EUF was studied. Oil sorption properties were measured by method ASTM (F726-81) while swelling kinetics was evaluated by an experimental equation. Compared with the granular and bulk oil sorbents based on EPDM, the gel EUF showed a fast swelling property and better oil sorption ability. tlle swelling time of EUF to kerosene, toluene, chloroform were 30min, 25min, 15min, the maximum values of oil sorbency were 20.12g/g, 22.739g/g, 35.22g/g, and the swelling kinetic constant were 8.42min<-1>, 14.22 min<-1>, 18.77 min<-1>, respectively.
