Buckypaper improves fire retardancy of plastic materials
Flame retardant materials have become a major business for the chemical industry and can be found practically everywhere in modern society. Unfortunately, conventional methods for making plastic flame retardant involve a range of often very toxic chemicals. Researchers have now shown that the use of buckypaper – macroscopic aggregates of intertwined CNTs in which the nanotubes collectively behave as a random web – is more efficient as a fire retardant in polymer composites in comparison to directly mixing carbon nanotubes (CNTs) into the composite matrix. According to the team, the buckypaper was far more efficient as a fire retardant in fibre/polymer composites than MWCNTs that were directly mixed with the polyimide resin. The buckypaper survived the burning test as a fire retardant shield with ash deposited on the burned composite surface. They conclude that the buckypaper acted as a shielding layer, obstructing the flow of heat and oxygen to the inner polymer matrix. To fabricate their buckpaper, the researchers purchased SWCNTs and MWCNTs off the shelf and used them without further purification. Through grinding and mixing with de-ionized water they formed a thick paste which they subsequently diluted, sonicated and filtrated through a nanomembrane (450 nm pore size) under vacuum pressure. Buckypaper with a thickness of 40 µm remained on the membrane and could then be peeled off.
