GRAPHENE OXIDE MICROCAPSULES (GOMs) WITH LINSEED OIL CORE VIA PICKERING EMULSION METHOD: EFFECT OF DISPERSE SPEED
نویسندگان
چکیده
Graphene oxide microcapsules (GOMs) have been prepared through Pickering emulsion method by varying the disperse speed to study its effect on GOM’s size. The GOMs were characterized phase separation observation, polarized optical microscope (POM), and particle size analyser (PSA). Phase observation showed more viscous cloudy was produced when increased. After 24 hours, only 800 rpm did not show any separation. POM characterization depicted that increasing emulsification energy led finer with 1200 sample showing smallest microcapsule of around 8 ?m. However, PSA analysis suggested although controls size, amount GO in plays an important role for maintain stability. Emulsion at possesses satisfactory stability diameter 11.15 result also graphene encapsulated linseed oil may act as a promising candidate healing self-healing coating system. ABSTRAK: Mikrokapsul oksida telah dihasilkan melalui kaedah emulsifikasi dengan memvariasikan tenaga pengemulsi untuk mengkaji kesannya terhadap saiz GOMs. dicirikan pemerhatian pemisahan fasa, mikroskop optik polarisasi (POM) dan penganalisis zarah Pemerhatian fasa menunjukkan emulsi yang lebih likat keruh apabila kelajuan meningkat. Selepas jam, hanya tidak fasa. Pencirian meunjukkan bahawa peningkatan menghasilkan halus sampel mikrokapsul terkecil, sekitar Walau bagaimanapun, analisis mencadangkan walaupun mengawal GOMs, jumlah dalam memainkan peranan penting mengekalkan kestabilan mikrokapsul.

متن کاملHollow hybrid polymer-graphene oxide nanoparticles via Pickering miniemulsion polymerization.
The preparation of hybrid hollow capsules consisting of a cross-linked polymer shell and a coating of graphene oxide (GO) is demonstrated. The capsules are prepared by Pickering miniemulsion polymerization, exploiting the surface activity of GO for its use as a colloidal surfactant. This approach represents a simple and convenient route towards hollow carbon nanostructures for a variety of appl...
متن کاملCore-shell microcapsules from clay-based Pickering emulsions
Core-shell microcapsules are typically made by preparing an emulsion and forming a polymer shell around the droplets. Conventionally, the emulsion is stabilised by surfactants or polymers. Alternatively, emulsions can be stabilised by fine particles; we discuss capsules made from ultrafine kaolin stabilised Pickering emulsions via interfacial polymerisation. This approach has a number of potent...
