Filem hibrid yang dihasilkan telah mempamerkan ketelusan optik yang sangat tinggi. Dengan penambahan 30 wt% zirkonium(IV)-n-propoksida, zarah-nano zirkonia telah diagihkan secara seragam dan homogen di dalam matriks ENR-50 dengan julat saiz zarah yang terdiri dari 50 hingga 70 nm.

Epoxidized natural rubber (ENR-50) was used as the polymer matrix and its composition with zirconium (IV)-n-propoxide and polyaniline (Pani) was investigated. The hydrogen bonding which contributes to the formation of the composite materials was observed by calorimetric and various spectroscopic analyses.
