Abstract
resumo fibras de baixa densidade e métodos para sua formação são fornecidas fibras que são formadas de uma composição termoplástica que contém um polímero e nanoestruturas de alta área de superfície. as fibras têm uma estrutura oca e baixa densidade, mantêm boas características de resistência. para conseguir tal estrutura, um agente de expansão na composição termoplástica é ativado durante a extrusão para formar bolhas nas fibras. as nanoestruturas de alta área de superfície nas fibras formadas podem ser formadas por ou podem transportar o agente de expansão e podem aumentar a resistência das fibras e compensar os vazios não estruturais das fibras. 1/1
