▎ 摘　　要

NOVELTY - Creating an aerogel (131), comprises forming a mixture of solid ammonia borane (111) and either (a) a two-dimensional nanostructured material (134) or (b) hydrocarbon polymer colloids (122), allowing the mixture to self-assemble to form many hybrid particles, and annealing the many hybrid particles at a first temperature to form the aerogel. USE - The method is useful for creating an aerogel which is useful: as a coating or as a structural component (claimed) e.g. fire-retardant, solar absorber, catalyst, electrode for energy storage, solar cells, supercapacitors, water desalination, purification, and separation, drug delivery, water purification and thermal platforms; or for e.g. mechanical damping, packaging, building insulation, automotive and aerospace applications. ADVANTAGE - The method provides the aerogel i.e. ultralight weight, environmentally friendly, heat-resistant and fire-resistant. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an aerogel obtained by the method; and (2) an aerogel comprising the colloidal nanoparticles (132) containing two-dimensional nanostructured material and hexagonal boron nitride. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the formation of aerogel.
