Abstract

<p>SE DESCRIBEN MÉTODOS PARA FORMAR UNA CAPA DE BARRERA SOBRE UN SUSTRATO PARA FORMAR UNA CONSTRUCCIÓN MULTICAPA SIN HALÓGENO CONFIGURADA PARA AUMENTAR LAS PROPIEDADES DE BARRERA DEL SUSTRATO. LA CAPA DE BARRERA PUEDE REDUCIR LA VELOCIDAD DE TRANSMISIÓN DE OXIGENO A TRAVÉS DE LA CONSTRUCCIÓN Y PUEDE REDUCIR LA CANTIDAD DE AIRE EN UN LADO DE LA CONSTRUCCIÓN. LOS MÉTODOS INCLUYEN DISOLVER UN POLÍMERO DE ALCOHOL VINÍLICO ALTAMENTE AMORFO EN DISOLVENTE PARA FORMAR UNA SOLUCIÓN Y APLICAR LA SOLUCIÓN AL SUSTRATO. LA SOLUCIÓN SE SECA PARA FORMAR UNA CAPA DE BARRERA SOBRE EL SUSTRATO. LA CAPA DE BARRERA ES CONTINUA, RELATIVAMENTE FINA Y TIENE UN ESPESOR CONSTANTE A LO LARGO DE LA CAPA DE BARRERA, PERO PROPORCIONA PROPIEDADES DE BARRERA MEJORADAS. LOS MÉTODOS PUEDEN INCLUIR EL USO DE CAPAS INTERIORES Y EXTERIORES IMPERMEABLES AL AGUA PARA EVITAR QUE EL AGUA LÍQUIDA Y EL VAPOR DE AGUA AFECTEN NEGATIVAMENTE AL FUNCIONAMIENTO DE LA CAPA DE BARRERA, Y UNA CAPA ADHESIVA PARA REDUCIR EL FALLO POR AGRIETAMIENTO POR FLEXIÓN DE LA CAPA DE BARRERA.</p>
