One of the alternatives for overcoming this problem is by adding an inorganic material into the polymer. Therefore, the objective of this work is to prepare PVDF/bentonite (BNT) hybrid membranes and to study intensively the effects of BNT on the properties of the resulting hybrid membranes. An exhaustive study covering the surface polymorphism, hydrophilicity, porosity, morphology, topography, mechanical properties and membrane performance toward two types of dyes have been carried out in this work. The ATR-FTIR analysis indicates that the β-phase structure coexists with the α-phase in all the membranes, while the contact angle measurement shows that all hybrid membranes are hydrophilic. The membranes also show high selectivity toward methylene blue and Reactive Yellow 145, indicating that the hybrid membranes can be used for improving the filtration of dyes.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Filtration process,High selectivity,Hybrid membrane,Inorganic materials,Membrane performance,Poly(vinylidene fluoride),Polyvinylidene fluorides,Separation process[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]bentonite,dyes filtration,hybrid membranes,Polyvinylidenefluoride[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors are thankful to Lembaga Penelitian dan Pengabdian Masyarakat (LPPM) Institut Teknologi Bandung Indonesia for providing the financial support for this research through the KK Research-Program A 2017.
