Multifunctional carboxymethyl cellulose nanofiber/liquid metal aerogels for sound absorption and heat insulation
Functional aerogels have attracted intensive attention due to their large specific surface area and light weight. In this study, liquid metal (LM) was uniformly dispersed into carboxymethyl cellulose nanofiber (CCNF) for fabricating sustainable CCNF/LM aerogel using a freeze-drying method. The as-fabricated CCNF/LM aerogel was characterized to understand its morphology, chemical components, crystal structure and surface structure, and the sound absorption together with thermal insulation of the aerogel were measured. The CCNF/LM aerogel exhibited good sound absorption, which can be attributed to the unique three-dimensional layered structure. Furthermore, the surface temperature of the CCNF/LM aerogel can be effectively decreased due to the heat absorption, reflection, and radiation of liquid metal. This work provides strategies in developing LM-aerogels toward application of in noise reduction and thermal insulation.
期刊介绍：
Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
