Phosphorus and inorganic fireproof paper

A research paper presents an experimentally developed phosphorus and inorganic based non-combustible nano-composite paper, using glass fibres (GF) coated with networked hydroxyapatite (calcium phosphate) ultra-long nano-fibres (HS-HANWs), generating a three-dimensional weave similar to cellulose paper structure.

The HS-HANW/GF paper offers smooth finish, high mechanical (tensile) strength, bio-compatibility (hydroxyapatite is the structure of bones), stability up to 1000°C and good thermal insulation. Experiments demonstrated the effectiveness of the HS-HANW/GF paper as a refractory protection for optical fibre cables. Possible other applications, if the product can be industrialised, could include non-flammable printing papers, fire-retardant wallpaper and biomedical applications.
