Abstract

This article reports the results of an investigation of the influence of single-walled carbon nanotubes (SWCNTs) functionalized with carboxyl groups on PVT data of water. Specifically, the impact of an aqueous suspension of SWCNTs (maximum concentration of 3.0 mg \(\cdot \) mL \(^{-1}\) ) on the isobaric thermal expansion of water in the temperature and pressure ranges of 293 K to 342 K and 0.1 MPa to 152.3 MPa, respectively, was investigated. The obtained results are discussed in terms of different structures of water confined inside and outside SWCNTs.
