Fig. 1

a Photograph of 3D hybrid aerogels prepared with 50:50 w/w ratio of PCL NF and MF coated with 1% gelatin (NF/MF-A1). b Photographs of NF/MF-A1 aerogels supported by a wooden wall or powder-free hand glove against gravity due to electrostatic forces. c–e Density, porosity, and pore size measurements of samples. Data are presented as mean values ± SD, N = 5. The significant difference was detected by one-way ANOVA with Tukey’s multiple comparisons test. The ‘ns’ indicated no significant difference, *p <  0.01, ****p <  0.0001. f–j SEM images of NFA, MFA, NF/MF-A1, NF/MF-A2, and NF/MF-A3. Right panel: enlarged images of yellow rectangular areas in the left panel. SEM imaging was repeated three times and similar results were obtained. NFA nanofiber aerogels coated with 1% gelatin. MFA microfiber aerogels coated with 1% gelatin. NF/MF-A1 hybrid aerogels containing NF/MF at a ratio of 50:50 (w/w) coated with 1% gelatin. NF/MF-A2 hybrid aerogels containing NF/MF at a ratio of 75:25 (w/w) coated with 1% gelatin. NF/MF-A3 hybrid aerogels containing NF/MF at a ratio of 25:75 (w/w) coated with 1% gelatin.
