Synergistic augmentation of polypropylene composites by hybrid morphology polyaniline particles for antistatic packaging applications

Abstract

In current study polyaniline filled polypropylene (PP/PAni) conductive composites were prepared by a novel premixing technique followed by melt mixing. The PP/PAni composites were also compatibilized by addition of polypropylene grafted maleic anhydride. Polyaniline was prepared by using ammonium per sulphate and ferric chloride as single oxidants. Effects of oxidizing agents (of polyaniline) on composites were studied by morphological, electrical and mechanical properties on composites. FTIR analysis was also carried out to study the nature of interactions and possible bonding between polyaniline and polypropylene matrix. Thermal analysis was carried out to study the thermal stability of composites. Morphological analysis revealed that the proposed premixing technique was quite successful in depositing polyaniline to polypropylene matrix. This analysis was also supported by the results of electrical conductivity where formation of conductive pathways were observed by addition of polyaniline thus converting insulating nature of polypropylene to a semiconducting one.

Synthesis and Conductivity Studies of Poly(Methyl Methacrylate) (PMMA) by Co-Polymerization and Blending with Polyaniline (PANi)

“…It is undeniable that by increasing the amount of PANi, a higher improvement in PMMA/PANi composites' conductivity is achieved [164][165][166][167]. However, many researchers agreed that the excess amount of PANi loading leads to the reduction of conductivity in the composite prepared [168][169][170]. Research done by Moussa et al (2017) reported that the direct current (DC) conductivity increased by about two orders of magnitude by increasing the PANi loading from 10% to the saturation loading of 70%.…”

Structural design of poly(vinyl alcohol)/carbon fiber composite film used for antistatic packaging via asynchronous biaxial stretching

“…To achieve light weight and good processability, the usually selected polymer matrices for antistatic packaging are polypropylene (PP) 10 and low density polyethylene (LDPE), 11,12 but they are generally electrical insulation 13 . So, polymer matrix with certain antistatic property and environmentally friendly will be appreciated.…”
