Özet

The paper presents the mechanical, morphological, thermal and the electrostatic charge dissipative (ESD) properties of binary blends of low-density poly (ethylene) (LDPE) blended with poly (1-amino-2-hydroxy naphthalene-4-sulfonic acid) (PANSA). Blends were prepared by loading 0.5, 1.0 and 3 wt% of PANSA into LDPE matrix in the twin-screw micro extruder. The interaction between PANSA and LDPE was then characterized by FT-IR, DSC, TG, DMA, AFM, SEM and X-RD techniques. The resulting polyolefin-based blends were also investigated by stress-strain curves in order to analyze some physico-mechanical properties. Percentages of the crystallinity of the blends were calculated by FT-IR, DSC and X-RD analyses. The conductivity of PANSA/LDPE blends was determined to be in the range of 10(-11) - 10(-12) S cm(-1) using ESD applications. The antistatic decay time of blend films was found to be of the order of 0.103-1.721 secat corona voltages between -3 kV and 3 kV, concluding that PANSA can be used as an effective ESD material for antistatic coatings of LDPE.
