“…[1] Making paper with inorganicn anowires instead of organic plant cellulose fibers seems to overturn the common understanding of the traditional papermaking, especially when the inorganic paper not only has the basic functions of the paper such as being writable, printable and copyable, but also exhibits features such as nonflammability and resistancet oh igh temperatures, which traditional plant cellulose paper does not possess. [2][3][4][5] Flexible, fire-resistant, and adiabatic paper is widely demanded in many fields such as aerospace, [6] vehicles, [7,8] batteries [9,10] and communication engineering. [11,12] The advantages of free-standing paper,s uch as being flexible, tailorable, writable, printable, user-friendly,a nd easy to use, can distinguish the paper from substrate-supported films, membranes and coatings.…”
