| ABSTRACT |
|
The retention capacity of microbes on the polyethylene surface was improved through the modi¬fications of polymer surface Out of six different chemical modifications, the LDPE(low density poly¬ethylene) samples treated by chlorosulfonic acid only and by chlorosulfonic acid + PEl(polyethylene imine) show most high retention capacities. The LLDPE(linear low density polyethylene) sample treated by chlorosulfonic acid + PE1 also shows good retention capacity of microbes. The surface analyses from ATR-FTIR and ESCA support that the sulfonyl group formed by chlorosulfonic acid treatment and the amide group formed by PEI treatment enhance the adhesion of microbes on the polymer surface. |
