Abstract
In this paper, preparation of novel organic phase-change materialsceramics nanofluids with high efficiency for thermal-energy storage and release is carried out, namely, the (PVA-PAA-NbC-H 2 O) nanofluids' and (PVA-PAA-NbC) nanocomposites' films are fabricated. The structural and dielectric properties of (PVA-PAA-NbC) nanocomposites are studied. The results show that the dielectric constant and dielectric loss of nanocomposites decrease with increase in frequency, while the electrical conductivity increases with increase in frequency. The dielectric constant, dielectric loss and electrical conductivity of (PVA-PAA) blend increase with increase in NbC nanoparticles' concentration. The results of thermalenergy storage and release for (PVA-PAA-NbC-H 2 O) nanofluids show that the melting and solidification times decrease with increase in NbC nanoparticles' concentration.
