Enhancement of mechanical and barrier properties of LLDPE composite film via PET fiber incorporation for agricultural application

Abstract

A study was conducted to determine the potential of linear low‐density polyethylene (LLDPE)‐PET fiber composite films to be used as an agricultural mulching film. Incorporation of 1 wt% PET fiber into the LLDPE matrix improved the tensile strength and percent elongation. The water vapor transmission rate was significantly lowered because of the presence of PET fibers. Also, the effect of continuous exposure of films to pesticide and UV light has been reported in terms of deterioration of mechanical and optical properties of the films. Differential scanning calorimetry shows that there is no effect of the presence of PET fibers on processing temperature of LLDPE at optimized loading; however, it was found that it lowers the latent heat of fusion and crystallization.

“…Poly(ethylene terephthalate) (PET) fibers are synthetic fibers with a high mechanical strength and elastic recovery ability and thus often used in the processing of clothing. 11 In this case, we use PET fibers as substrate material to design a flexible electronic device since it provides flexibility and conformability of the material as well as effectively avoids plastic deformation caused by mechanical pressure. 12 MWCNTs have a shielding effect against EMI due to their conductivity and internal porous structure and morphology.…”
