Summary Understanding structure-property relationship between polymer-nanoparticle interface and the distribution of interfacial region and its properties is crucial in establishing the bulk properties of polymer like mechanical stability and conductivity. In this article we try to draw a comparison of the effect of silica nanoparticles modified with three different modifiers on the properties of oxy-polybenzimidazole (OPBI) to understand the role played by the chemical structure of the organic modifying molecule. We highlight how small changes in the structure of the chosen molecule can bring about substantial improvements in polymer nanocomposites owing to the self-assembly of nanofillers. We use aminopropyltriethoxysilane (AMS), N-(3-trimethoxysilylpropyl) diethylenetriamine (LAMS) and ionic liquid modified silica (ILMS) for the surface modification of silica nanoparticles. The extent of interfacial interaction between each of these silica nanoparticles with OPBI matrix was found to be in the order OPBI/AMS
