摘要

With the increase in development in various countries, energy consumption across the world has increased mainly due to environmental comfort such as space heating and air conditioning in a building. This energy consumption can be reduced by the application of thermal insulation material. Aerogels are the promising material for thermal insulation property. Among various types of available polymer for preparation of aerogels, cellulose is a bio-polymer having renewable, biodegradable and biocompatible property. In this work, cellulose aerogel composite was prepared with cellulose aerogel and polyester batting by dissolving cellulose in N-methyl morpholine N-oxide solvent. Cellulose solution was then allowed to form gel within batting, which was regenerated with water, washed and freeze dried. The prepared composite has three dimensional porous structure. Density of the prepared composite is 0.05 g/cm3 and porosity is 96.5%. The thermal insulation value of prepared composite is 0.133 m2K/W which is 48.27% higher than the batting. The tensile strength and elongation was found 36 N and 20.8% respectively.
