“…Faktor seperti nisbah surfaktan:kosurfaktan (S/KoS), panjang rantai kosurfaktan dan jenis rantai hidrokarbon fasa minyak dilaporkan mempengaruhi pembentukan mikroemulsi (Basheer et al 2013;Sripriya et al 2007). Contohnya, panjang rantai fasa minyak perlu sesuai dan mudah berinteraksi dengan panjang rantai surfaktan (Sripriya et al 2007). Fasa minyak-air distabilkan apabila molekul surfaktan berupaya menyusun dengan membentuk lapisan filem yang mengurangkan tegangan permukaan seterusnya mendorong percampuran minyak dan air (Basheer et al 2013;Sripriya et al 2007).…”

Penambahan kosurfaktan dalam penyediaan mikroemulsi adalah perlu untuk mengurangkan ketegangan fasa minyak-air, seterusnya meningkatkan pembentukan sistem mikroemulsi (Basheer et al 2013).…”

“…Penyediaan mikroemulsi dilakukan dengan peningkatan berat air yang diwakili oleh anak panah sebagai garis pencairan air seperti yang ditunjukkan setiap gambar rajah fasa. Gambar rajah fasa pseudo-ternari bagi sistem mikroemulsi yang terdiri daripada fasa minyak tunggal ( Pembentukan mikroemulsi dipengaruhi oleh struktur dan sifat fasa minyak, surfaktan dan kosurfaktan (Agubata et al 2014;Basheer et al 2013;Sripriya et al 2007 (Fanun 2010(Fanun , 2007Sripriya et al 2007). Hal ini adalah kerana minyak daripada kumpulan ini dilihat berupaya menembusi serta menyusun di antara lapisan molekul surfaktan pada fasa antara muka minyak-air dan memperluaskan keratan rentas per surfaktan, seterusnya menstabilkan pembentukan sistem mikroemulsi (Fanun 2010 (<100 nm) (Talegaonkar et al 2008).…”

“…To obtain the composition of the microemulsion phase after the separation, the volume of the oil phase in excess (WIII systems) and the aqueous phase in excess (WII and WIII systems) were measured and it was assumed that all active material (C/S ratio) remained in the microemulsion phase. According Sripriya et al (2007), in microemulsion systems, viscosity is a macroscopic property which largely depends upon to the type of aggregates present, on their interactions, and on its concentration. Thus it is mainly used to monitor the microstructure of the system.…”

-Microemulsion systems were used to remove chromium from an aqueous solution obtained from acid digestion of tannery sludge. The systems were composed by: coconut oil soap as surfactant, 1-butanol as cosurfactant, kerosene as the oil phase, and chromium solution as the aqueous phase. Two-and three-phase microemulsion extraction methods were investigated in the experiments. Viscosity, effective diameter of the droplets, and extraction and re-extraction efficiencies were evaluated for each system. Two-and three-phase systems showed small variations in droplet diameter, which can be attributed to the formation of micellar structures. Chromium recovery efficiencies for the studied systems were over 96%. The re-extraction step showed that the stripping solution used can release more than 96% of the chromium from the microemulsion phase. Experimental results confirm that chromium can be recovered efficiently using microemulsion systems.

In recent decades, there has been a great deal of interest in conducting polymers due to their broad applications. At the same time, various synthetic techniques have been developed to produce various nanostructures of the conducting polymers with their fascinating properties. However, the techniques for the manufacture of 2D nanosheets are either complex or expensive. No comprehensive approach for constructing 2D and 3D materials or their composites has been documented. Herein, a simple and scalable synthetic protocol is reported for the design of 2D, 3D, and related conducting polymer nanocomposites by interface manipulation in a bicontinuous microemulsion system. In this method, diverse bicontinuous thin layers of oil and water are employed to produce 2D nanosheets of conducting polymers. For the fabrication of 3D polypyrrole (PPY) and their composites, specially designed linkers of the monomers are applied to lock the 3D networks of the conducting polymers and their composites. The technique can be extended to the fabrication of most conducting polymer composites, being cost‐effective and easily scalable. The optimum electrical conductivity obtained for 2D PPY nanosheets is 219 S cm−1, the highest literature value reported to date to the best of knowledge.
