Morphological Parameter Study of Polymer By Using Small Angle X-Ray Scattering Method

Thermoplastic natural rubber sample is found isotropic based on SAXS pattern. Morphological parameter was obtained based on ideal lamellar morphology using 1-D correlation function. The fitting was carried out using Porod tail model and Vonk for back-extrapolated model. It is found that the long period value is 15.7nm which is comparable to results obtained from Lorents corrected profile, 20nm. Crystalline thickness and amorphous thickness was found as 13.4 and 2.31nm respectively. ABSTRAK Sampel getah asli termoplastik didapati isotropi berdasarkan corak SAXS. Parameter mofologikal diperolehi berdasarkan morfologi lamela unggul dengan menggunakan rangkap korelasi 1-D. Pemadanan dijalankan menggunakan ekor Porod model dan Vonk untuk belakang mengekstrapolasikan model. Ia didapati bahawa nilai jangka masa yang panjang ialah 15.7nm keputusan-keputusan setanding dengan yang mana diperolehi dari Lorents membetulkan profil, 20nm. Ketebalan berhablur dan ketebalan amorfus didapati kerana 13.4 dan 2.31nm masing-masing.
