Abstract

Se proporciona un artículo absorbente que contiene una película de poliolefina. Se proporciona la película de poliolefina que se forma por una composición termoplástica que contiene una fase continua que incluye un polímero de la matriz de poliolefina y aditivo de nanoinclusión. El aditivo de nanoinclusión se dispersa dentro de la fase continua como dominios discontinuos de fase a nanoescala. Cuando se estiran, los dominios de fase a nanoescala son capaces de interactuar con la matriz de una manera única para crear una red de nanoporos.
