Abstract
estruturas de múltiplas camadas não tecidas, tendo camadas de nanofibr. estruturas de múltiplas camadas não tecidas tendo pelo menos duas camadas de nanofibras são aqui descritas. a estrutura de múltiplas camadas não tecidas pode ter duas camadas de nanofibras que têm propriedades diferentes uma da outra, tal como o diâmetro da fibra. uma camada de nanofibra pode ser produzida por um processo de eletrofiação, enquanto outra camada de nanofibra pode ser produzida por um processo de sopro por fusão.
