In order to prove the validity of this theory, various polymer and solvent mixture had been used for the data sample. There were six kinds of polymer solution to be analyzed in this study. Each type of polymer solution shows a different relation with solution concentration. This situation signifies that there was another parameter contributes in determining fiber diameter besides solution concentration. Based on data, the electronegativity of polymer and vapor pressure of solvent takes a significant contribution in determining fiber diameter. This empirical study results a fiber diameter equation as a function of terminal jet radius, electronegativity of polymer, the vapor pressure of solvent, and flow rate. The resulting equation provides higher accuracy compared to the previous empirical equation, where the fiber diameter only depends on solution concentration. Besides, these results prove that ambient parameter provides great impact in solidification phase in electrospinning. Thus, the contribution of the solution, ambient condition, and electrical parameters to fiber diameter in electrospinning could be summarised in a single equation.[/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]Ambient conditions,Electrical parameter,Empirical equations,Empirical studies,Single equation,Solution concentration,Solvent mixtures,Solvent parameter[/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][/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][/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/1445/1/012025[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
