Abstract Insertion of 2:1 organo‐modified phyllosilicate tactoids into rheologically tough thermoplastics has extraordinary potential candidate in oxygen permeability and microstructural toughening. Herein, two commercially abundant clays have been taken for improvement the thermoplastic's gas barrier property reasonably low loading. The cause loading accounted to usage maleated polyethylene (MA‐g‐PE) during melt mixing tenure. optimized nanocomposite compression molded film tested against uniaxial stretching, which showed a negligible change residual permanent set with sacrificing elongation at break feature. Moreover, nanoindentation was also performed get hardness sample surface. flow behavior nanocomposites thixotropic likely increasing frequency. Oxygen transmission rate (OTR) significantly decreased tallow amine‐modified nanoclay system (cloisite 15A) comparison cloisite Na + providing 'tortoise path' formation inside matrix. Thus, hitherto, work could demonstrate provide information comparative studies between organo‐clay simple phyllosilicates, be remediation loopholes mechanical toughening lineaments.
