Synthetic leathers made of PU (polyurethane) and fibrous nonwoven substrate are used in various industries. However, most of the materials cause health hazards and environmental constraints. An alternative solution is fungi-based leathers. It can be facilitated by less water and energy use in polymer manufacturing in few weeks. To further influence its properties such as flexibility and toughness, we conduct the synthesis and characterization of fungal leather developed from a waterborne polyurethane(WPU) surface, which is customized without any harmful compatibilizer or solvent. The recyclability and degradability provided by these materials at the end of its useful life make it more suitable for leather. Several instrumental analysis such as FT-IR, SEM and DSC were performed to characterize the structure and properties of the prepared WPU and fungal substrate. The WPU has a lower glass transition temperature and a higher decomposition temperature than the conventional PU sample. |
