Abstract
Electrospinning itself allows production of composite membranes, while two nozzle set-up is used1. In our studies we electrospun layer by layer two types of polymers: hydrophobic polystyrene (PS) and hydrophilic polyamide 6 (PA6) to obtained controlled wetting and mechanical properties of the produced membranes. PS (25%wt.) was dissolved in dimethylformamide (DMF) and PA6 (12%wt.) in mixture of formic and acetic acids (volume ratio 1:1). The prepared solutions were electrospun according to our previous study2. We produced PS-PA6 layer composites using two nozzles electrospinning setup (Apparatus ECDIG with Climate-control, IME Technologies, the Netherlands) and with control of hydrophobic and hydrophilic part by deposition time. The fibers and composites morphology were analyzed using Scanning Electron Microscope (SEM, Merlin Gemini II, ZEISS, Germany). The mechanical properties were verified by tensile module with 1 N Load Cell (Kammrath Weiss GmbH, Germany). Advancing and dynamic water contact angles were measured on produced mats in horizontal and vertical position respectively. The advancing contact angle for PS fibers mat was 142 ± 2°, whereas for PA6 was 45 ± 2°. The combining of hydrophobic PS and hydrophilic PA6 caused that received contact angle was 123 ± 2°. This fiber based composite showed the increased mechanical stress than mats based on PS fibers only. The dynamic contact angle in vertical settings showed that our composite are able to collect water to increase the already used membranes in water harvesting applications.
