In vitro studies of PBT Nonwoven Fabrics adsorbent for the removal of low density lipoprotein from hyperlipemia plasma

► Heparin and polyacrylic acid were grafted on PBT Nonwoven Fabrics surface to study their effect on the adsorption of low density lipoprotein and blood compatibilities. ► The adsorption efficiency of LDL was greatly increased by immobilized of PAA. ► And the immobilization of heparin could improve PBTNF-PAA's blood compatibility and decrease the adsorption capability of useful high density lipoprotein significantly.
