Nanoclay-Based PVA Aerogels: Synthesis and Characterization

Nanoclay-based PVA aerogels have been synthesized at pilot-plant scale, using an environmentally friendly freeze-drying method. In the present work, the influence of different types of nanoclays on the physical, mechanical, and thermal properties of the resulted PVA aerogels were evaluated. In addit...

En el presente trabajo se evaluó la influencia de diferentes tipos de nanoarcillas en las propiedades físicas, mecánicas y térmicas de los aerogeles de PVA resultantes. Además, se estudió el efecto de la relación de masa nanoarcilla/PVA. La incorporación de nanoarcilla en la matriz polimérica dio como resultado estructuras compactas con una distribución de tamaño de poro pequeña. Además, la adición de nanoarcillas (hasta un 3 % en peso) permitió mejorar las propiedades mecánicas de los aerogeles obtenidos. Los aerogeles de PVA basados ​​en nanoarcillas mostraron propiedades interesantes, como alta ligereza, buenas propiedades mecánicas, baja conductividad térmica y resistencia al fuego.ACS Publications202220222018info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/29770reponame:RUIdeRA.
