“…As a result, PEG is one of the most widely used polymers for the creation and growth of a wide range of vital applications [14]. There are several studies on PEG and PVA nanocomposites for various applications like energy storage [15][16][17], antibacterial [18] and humidity sensors [19][20][21]. This paper aims to prepare the PVA-PEG-Cr2O3 nanocomposites and investigating its optical properties.…”

In this study, many samples have been synthesized by using solution casting technique with different additive content of Chromium oxide nanoparticle (Cr2O3NPs), poly vinylalcohol (PVA) and polyethylene glycol (PEG). The UV-Vis. spectrophotometer used to record the absorbance spectrum in the range of (200-800) nm. The absorption of UV waves is improved while the transmittance is reduced when Cr2O3 NPs were added to the polymeric system which are useful for a number of applications including low-cost UV protection and solar radiation shield. When Cr2O3 NPs concentrations increased, the optical energy gap for indirect transition (allowed and forbidden) was decreased. Furthermore, all the optical constant has been improved.

“…Effective dispersion of (SnO2-TaC) and (SnO2-SiC) nanoparticles into base fluid were accelerated the conductive heat transfer during the process of melting and solidification where the nanoparticles form a paths network inside the nanofluids. The water/PEGwith (SnO2-TaC) and (SnO2-SiC) nanoparticles nanofluids could be considered efficient for solar water heating system due to their characteristics of enhanced heat transfer [5][6][7][8][9][10][11][12].…”

The thermal energy storage and release application of water- phase change material- (SnO2-TaC) and (SnO2–SiC) nanoparticles system has been investigated for cooling and heating applications. The water - polyethylene glycolwith (SnO2-TaC) and (SnO2–SiC) nanoparticles have been used. The results showed that the melting and solidification times for storage and release of thermal energy of water - polyethylene glycoldecrease with increase in(SnO2-TaC) and (SnO2–SiC) nanoparticles concentrations. The melting and solidification times decrease with increasing of TaC nanoparticles concentrations to water-polyethylene glycol/SnO2nanofluidand SiC nanoparticles concentrations to water-polyethylene glycol/SnO2nanofluid.

Nanocomposites are actually promising materials in many modern industrial or medical applications, which are attributed to their good properties such as light weight, high flexibility, resistance to oxidation, cheap price, good electrical, optical, and mechanical properties. In this paper, fabrication of polyvinyl alcohol (PVA)-polyacrylic acid (PAA)-titanium nitride (TiN) nanocomposites with low weight, low cost, high corrosion resistance and high efficiency for thermal energy storage and release is investigated. The structural and dielectric properties of (PVA-PAA-TiN) nanocomposites are studied. The experimental results show that the dielectric constant and dielectric loss of (PVA-PAA-TiN) nanocomposites decrease with increase in frequency, while the electrical conductivity increases as frequency increases. The dielectric parameters of polymer blend increase with increase in TiN-nanoparticles' concentration. The results of solar energy storage and release show the decrease in melting and solidification times as the TiN-nanoparticles' concentration increases.Нанокомпозити насправді є перспективними матеріялами в багатьох сучасних промислових або медичних застосуваннях, які приписуються їхнім хорошим властивостям, таким як невелика вага, висока гнучкість, стійкість до окиснення, дешева ціна, хороші електричні, оптичні та механічні властивості. У цій роботі досліджено виготовлення нанокомпозитів полівінілалкоголь (ПВА)-поліакрилова кислота (ПАК)нітрид титану (TiN) з низькою вагою, низькою вартістю, високою корозійною стійкістю та високою ефективністю для зберігання та вивільнення теплової енергії. Досліджено структурні та діелектричні властивості нанокомпозитів (ПВА-ПАК-TiN). Експериментальні результати показують, що діелектрична проникність та діелектричні втрати нанокомпозитів (ПВА-ПАК-TiN) зменшується зі збільшенням частоти, в той час як електропровідність збільшується зі збільшенням частоти. Діелектричні параметри полімерної суміші збільшуються зі збільшен-
