Abstract

componente de transferência de calor e massa compreendendo uma superfície impregnada de lubrificante. a presente invenção refere-se a um componente de transferência de calor e massa que compreende uma superfície impregnada de lubrificante contendo elementos superficiais hidrofóbicos, que compreendem saliências superficiais nanoestruturadas que incorporam uma espécie hidrofóbica. os elementos superficiais hidrofóbicos são impregnados com um lubrificante à base de flúor que tem uma viscosidade em uma faixa de cerca de 400 mpa.s a cerca de 6000 mpa.s. um método para fabricação de uma superfície impregnada de lubrificante sobre um componente de transferência de calor e massa compreende: limpar um substrato termicamente condutor para formar um substrato limpo; expor o substrato limpo a uma água quente ou solução alcalina quente para formar um substrato termicamente condutor dotado de saliências superficiais nanoestruturadas; depositar uma espécie hidrofóbica sobre as saliências superficiais nanoestruturadas para formar elementos superficiais hidrofóbicos; e revestir os elementos superficiais hidrofóbicos com um lubrificante à base de flúor que tem uma viscosidade em uma faixa de 400 mpa.s a 6000 mpa.s. o componente de transferência de calor e massa pode exibir um aumento substancial do coeficiente de transferência de calor durante a condensação de hidrocarbonetos.
