摘要
Melt-blown polybutylene terephthalate (PBT) nonwoven materials treated by usingplasma is regarded as one of the excellent materials to filter white blood cells (WBC) from blood.In this paper, dielectric barrier discharge (DBD) plasma source at an improved quasi-stable at-mospheric pressure is achieved when discharge voltage, discharge current, and gap between theelectrodes are carefully controlled. This plasma source has been used to modify the surface ofPBT melt-blown nonwoven materials. Experimental results indicate that both the wettablity andpermeation of treated PBT melt-blown nonwoven materials are greatly improved.
