Abstract

Telah dilakukan penelitian pengaruh kosentrasi HCl dan Sodium Dodecyl Benzene Sulfonate (SDBS) terhadap konduktivitas listrik polianilin dengan metode polimerisasi emulsi. Polianilin dibuat dari monomer anilin dengan metode polimerisasi emulsi. Polianilin yang telah terbentuk, konduktivitas listrik ditingkatkan melalui doping HCl dan SDBS. Konsentrasi HCl divariasikan 0, 1, dan 3 M, sedangkan SDBS divariasikan 0; 0,2; dan 0,4 mol. Serbuk PANI hasil sintesis dibentuk menjadi pellet, kemudian dilakukan karakterisasi. Gugus fungsional pada PANI terdoping diamati dengan FTIR, struktur kristal menggunakan XRD dan konduktivitas listrik menggunakan RCL meter. Hasil uji FTIR menunjukkan adanya gugus fungsional benzoid dan kuinoid masing-masing pada bilangan gelombang sekitar 1454 dan 1531 cm-1 yang mengindikasikan terbentuknya garam emeraldin PANI. Terdapat puncak bilangan gelombang sekitar 1250 cm -1 sesuai dengan keadaan konduktif polimer PANI yang didoping. Pola difraksi sinar-X teridentifikasi puncak difraksi pada 2θ sekitar 19 dan 25°. Ukuran kristal dihitung menggunakan persamaan Scherrer untuk PANI didoping HCl 0, 1 dan 3 M masing-masing adalah 0,4235; 0,5547; dan 0,4432 nm sedangkan PANI dengan penambahan SDBS 0; 0,2; dan 0,4 mol adalah 0,4762; 0,5547; dan 0,5143 nm. Hasil uji RCL meter menunjukkan konduktivitas listrik AC tertinggi pada PANI didoping HCl 1 M dan penambahan SDBS 0,2 mol dengan rentang 226 hingga 1220,2 S/m dalam interval frekuensi 103- 106 Hz. Semakin tinggi doping HCl yang diberikan akan meningkatkan konduktivitas dan kristalinitas PANI, namun jika HCl melebihi 1 M akan menyebabkan degradasi rantai polimer dan penambahan SDBS lebih dari 0,2 mol molekul PANI menghambat transmisi elektron, sehingga menurunkan konduktivitas listrik PANI.

Research the effect of concentration of HCl and Sodium Dodecyl Benzene Sulfonate (SDBS) on the electrical conductivity of polyaniline by emulsion polymerization method has been carried out. Polyaniline was made from aniline monomer by emulsion polymerization method. The electrical conductivity of formed polyaniline increased through HCl and SDBS doping. The concentration of HCl was varied 0, 1, and 3 M, while SDBS 0; 0.2; and 0.4 moles. The synthesized PANI powder was formed into pellets, then characterized by FTIR to observe functional groups in doped PANI. The crystal structure be identified using XRD and electrical conductivity measured by RCL meter. FTIR results showed the presence of benzoid and quinoid functional groups at wave numbers around 1454 and 1531 cm-1, respectively, which indicate the formation of PANI's emeraldine salt. There is a peak wave number of about 1250 cm-1 in accordance with the conductive state of the doped PANI polymer. The X-ray diffraction patterns were identified at 2θ around 19 and 25°. The crystal size be calculated using the Scherrer equation for doped PANI with HCl 0, 1, and 3 M were 0.4235; 0.5547; and 0.4432 nm respectively. Crystal sizes of PANI with the addition of SDBS 0; 0.2; and 0.4 mol were 0.4762; 0.5547; and 0.5143 nm respectively. The results of the RCL meter test showed the highest AC electrical conductivity for 1 M HCl doped PANI and the addition of 0.2 mol SDBS in the range of 226 to 1220.2 S/m at frequency interval of 103-106 Hz. The higher HCl doping given will increase the conductivity and crystallinity of PANI, however if HCl exceeds 1 M it will cause polymer chain degradation and the addition of SDBS of more than 0.2 moles of PANI molecules inhibits electron transmission, thereby reducing the electrical conductivity of PANI.
