ABSTRACT

 

Polyaniline montmorillonite nanocomposite was prepared using H2O2 as the oxidant. The catalytic environment of montmorillonite favours polymerization. Intercalation and composite formation was proven from various techniques such as XRD, FTIR, DRS and thermal analysis. XRD patterns give the dimension of the intercalated PANI, from the shift of 2θ values, which is in the nano range. FTIR showed that PANI composite formation occured without affecting the basic clay layer structure. Thus the successful development of an alternative cheap route for polyaniline–montmorillonite nanocomposite was well established.

 

Keywords: Chemical synthesis; montmorillonite; polyaniline nanocomposite

 

ABSTRAK

 

Komposit nanopolianilin-montmorilonit telah disediakan dengan menggunakan H2O2 sebagai pengoksida. Montmorilonit bersifat pemangkin yang dapat membantu pempolimeran. Kemasukan dan pembentukan komposit telah dibuktikan melalui berbagai ujian seperti XRD, FTIR, DRS and analisis terma. Corak ujian XRD membuktikan adanya kemasukan PANI yang dapat dilihat melalui perubahan nilai 2θ, yang merupakan julat nano. Ujian FTIR menunjukkan pembentukan komposit PANI terjadi tanpa mengganggu struktur asas lapisan tanah liat. Kajian ini telah menghasilkan kaedah alternatif untuk menghasilkan komposit nano polianilia–montmorilonit dengan kos yang rendah.

 

Kata kunci: Komposit nanopolianilia; montmorilonit; sintesis kimia
