P08 ELECTRODEPOSITION OF POLYPYRROLE/REDUCEDGRAPHENE OXIDE/IRON OXIDE NANOCOMPOSITE FORSUPERCAPACITOR APPLICATIONY.C. Euu, H.N. Lim*Department of Chemistry, Faculty of Science, Universiti Putra Malaysia, 43400 UPMSerdang, Selangor, MalaysiaCorresponding author: hongngee@upm.edu.myIn this research, polypyrrole (PPy) was reinforced with reduced graphene oxide (rGO)and iron oxide to achieve electrochemical stability and enhancement. The ternarynanocomposite was prepared using a facile one-pot chronoamperometry approach,which is inexpensive and experimentally-friendly. The x-ray diffraction(XRD) profileshowed the presence of PPy and a combination of Fe 2 O 3 and Fe 3 O 4 . The typical peakof graphene oxide (GO) was absent from XRD, indicating reduction of GO. This wasalso confirmed by the presence of a peak at 26 o , indicating π-π stacking interaction ofrGO sheets. The cyclic voltammetry (CV) analysis illustrated enhanced current for thenanocomposite by more than twofold and sevenfold compared to its binary andindividual counterparts, respectively. After the 20 th cycle, the ternary nanocompositeremained stable and still adhered onto its substrate. The initial and final specificcapacitances were 115.3 F/g and 102.2F/G after 200 cycles. The sample exhibitedexcellent specific capacitance retention as there was only 11.4% of reduction.23 |16 th Industrial Chemistry Seminar: Chemistry- A Passport to a Brighter Future
P09 SYNTHESIS AND CHARACTERISATION OFPROBENECID-LAYERED DOUBLE HYDROZIDENANOCOMPOSITE1 H.H. Chua, 2, M.Z. Hussein*, 2 S.M. Nabil Mohsin and 1 R. Abdul Manap1 Department of Chemistry, Faculty of Science, Universiti Putra Malaysia, 43400UPM Serdang, Selangor, Malaysia2 Material Synthesis and Characterization Laboratory (MSCL), Institute of AdvancedTechnology (ITMA), Universiti Putra Malaysia, 43400 UPM, Serdang, Selangor,Malaysia.Corresponding author: mzobir@putra.upm.edu.myProbenecid has antibiotic, antiviral and antimicrobial properties. In the past fewdecades, probenecid has been widely used in prevention of rheumatism and treatmentof Parkinson’s disease. Probenecid has potential use as inotrope drug for heart failuretreatment due to its competitive inhibitor characteristicS. In this study, Probenecidwas intercalated in its anionic form into layered double hydroxide (LDH), ahydrotalcite-like material, using direct co-precipitation method. Synthesis parameterssuch as pH condition, metal cation molar ratio and guest anion concentration wereinvestigated to optimize drug intercalation. Successful intercalation of Probenecid intoLDH interlayer was confirmed with powder x-ray diffractometer (PXRD), Fouriertransform infrared spectrometer (FTIR), direct injection mass spectrometer (DIMS)and carbon, hydrogen, nitrogen and sulfur (CHNS) analyzer. PXRD patterns of thenanocomposite showed an increase of basal spacing from 7.9 Å (pristine Zn/Al-NO 3LDH) to 27.9 Å. In addition, controlled released property of the intercalated LDH wasinvestigated using simulated gastrointestinal fluid (pH 4.8) and plasma fluid (pH 7.4).The results showed that drug release from LDH layers is a relatively slow andsustained process. This indicates potential for the synthesized Probenecid-LDHnanocomposite to be used as an effective drug delivery system.24 |16 th Industrial Chemistry Seminar: Chemistry- A Passport to a Brighter Future
