Abstract Superior thermal insulating and fire-retardant ceramic membranes are urgently demanded in the aerospace, construction and chemical engineering industries. However, the generic characteristics of ceramic membranes, such as brittleness, structural collapse and crystallization-induced pulverization behavior, present a great plague to their practical applications. Herein, we report a highly flexible, mechanically stable, fire retardant and high-temperature-resistant ceramic membrane based on the interlocked Si3N4 nanowires formed by the precursor pyrolysis method. The Si3N4 nanowires membrane (SNM) has excellent high temperature resistance under alcohol lamp and butane spray lance. The thermal insulation with a thermal conductivity as low as 0.056… More >
