Development of PVA/PEG-silane composites pillared activated bentonite for hydrophilic sponge material

Abstract Hydrophilic sponge composites were designed with a combination of polymers using silane agent (Polydimethylsiloxane (PDMS), Octhyltriethoxysilane (OTES)), Polyethylene glycol (PEG), Polyvinylalcohol (PVA) and activated natural bentonite (B). We describe simple method hydrophilic preparation characteristics. The was proceeded by washing in distilled water followed curing heated at 150°C for 1 hour. V1 prepared the ratio PDMS: Zn: PVA: PEG= 1: (w/w). Through same synthesis steps, we also V2 (2:1:1:1), V3 (1:1:2:1), V4 (1:1:1:2). Then, (B) added to V1, V2, V3, composites, respectively, obtained B-V1 PDMS, B-V2 B-V3 B-V4 OTES, OTES. research studies physical characteristics bentonite, PVA/PEG-silane X-Ray diffraction (XRD), Attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, Scanning Electron Microscopy (SEM). Even though, characteristic sponges identified contact angle measurement. It has been observed that most materials are PDMS presence more PEG can cause be smaller or hydrophilic, but its needs limited further reviewed regarding solubility fuel oil. concludes potential application as separation from
