Designing dual phase sensing materials from polyaniline filled styrene-isoprene-styrene composites
Sadasivuni, Kishor Kumar; Ponnamma, Deepalekshmi; Kasak, Peter; Krupa, Igor; Al-Maadeed, Mariam Ali S.A. ( Elsevier Ltd , 2014 , Article)The demand for developing oil detectors is ever increasing since the cleanup and recovery from oil spill usually take long time. Here we propose oil sensors made of polyaniline (PANI) filled poly(styrene-isoprene-styrene) ... -
Electrospun Polysulfone Hybrid Nanocomposite Fibers as Membrane for Separating Oil/Water Emulsion
Ponnamma, Deepalekshmi; Elgawady, Yara; Hassan, Mohamed K.; Adham, Samer; Al-Maas, Mashael; Alamgir, Karim; Al-Maadeed, Mariam Al Ali... more authors ... less authors ( Springer Nature , 2023 , Article)Commercial polymer membranes are largely utilized to separate oil/water mixtures; however, membrane fouling, flux decline, and short lifetime often inhibit their high performance. In order to resolve these drawbacks of the ... -
Laser Induced Periodic Surface Structures on Nano Metal Oxide filled Polyvinylidene Fluoride Nanocomposites
Ponnamma, Deepalekshmi; Sivakumar, Velautham; Popelka, Anton; Hussein, Yasser H. A.; Al-Maadeed, Mariam Al Ali ( Elsevier , 2018 , Article)The ability of polarized pulsed laser in surface modification of substrate surfaces without thermally destroying them is a well-established concept of scientific procedure. In this work, we report the laser induced surface ...
