摘要

In this work

PTFE aerogels with excellent sound absorption and thermal insulation properties were successfully prepared. In addition

the PTFE aerogels had good temperature and corrosion resistance

which exhibit great potential for application in harsh environments.

Abstract

As the application scenarios of aerogels expand

higher requirements are put forward for the materials used to prepare aerogels. Due to the unique chemical structure

polytetrafluoroethylene (PTFE) has excellent properties such as high-temperature resistance

hydrophobicity

and chemical stability. However

the PTFE aerogels are difficult to be molded due to the weak interaction between resin particles. In this work

poly(ethylene oxide) (PEO) was selected as the carrier to assist the PTFE aerogels molding. The pure PTFE aerogels were prepared by homogeneously mixing PTFE aqueous dispersion and PEO

freeze-drying

and high-temperature sintering. When the mass fraction of PTFE and PEO were appropriate

the porosity of PTFE aerogels exceeded 90% and had a hierarchical honeycomb structure. Results showed that the PTFE aerogels not only had excellent hydrophobicity but also possessed superior acoustic insulation

mechanical strength

thermal insulation

and heat resistance properties. Specifically

the water contact angle is about 140°. The noise reduction coefficient is 0.34 and the average sound absorption coefficient is greater than 88% in the frequency range of 2000–6400 Hz. Meanwhile

the thermal conductivity in the air is about 0.045 W/(m·K)

and the initial thermal decomposition temperature is 450 °C. More importantly

the PTFE aerogels had excellent temperature and corrosion resistance. Even after extremely thermal and chemical treatment

they remained unchanged porous structure as well as acoustic and thermal insulation properties

which exhibits great potential for application in many harsh environments.
