The polysiloxane–TiO2 nanocomposites were prepared by a solvent casting method in triethanolamine and tetrahydrofuran solvents. The prepared nanocomposites were characterized by X-ray diffraction technique, Fourier transform infrared spectroscopy, and scanning electron microscopy for structural analysis and surface morphology. The amorphous nature of polysiloxane observed in XRD spectra and FTIR spectra shows the characteristic peaks of Si–CH2, Si–CH3, and Ti–O–Ti, confirming the formation of nanocomposites. The surface morphology shows the nanoparticles are completely embedded in the polysiloxane. Furthermore, the DC conductivity shows the increase in conductivity with the increase in temperature due to tunneling phenomena. The wet contact angle of pure polysiloxane was 78.3° before being exposed to UV light and upon the addition of TiO2 in PS the WAC increased to 88.2° which clearly indicates that the nanocomposites are superhydrophobic in nature. Among all the nanocomposites of different weight percentages, 0.3 wt% shows the highest DC conductivity of 6 × 10−5 S/cm. The dielectric spectroscopy study reveals low dielectric constant and tangent loss for 0.3 wt% nanocomposite; as a result it shows the highest conductivity of 1.35 × 10−4 S/cm. The quality factor confirms that there is a small damping loss for 0.3 wt% of nanocomposites which is favourable for high conductivity.

Composite alloys are said to be the materials mixture two or more components which gives more strength and effectiveness to the fabricated component where it is used. Majorly these composites are being played a vital role in consideration to heat transfer in these days. We all know that the Heat Exchanger is gadget constructed for environment friendly heat transfer from one fluid to any other in which either wall to cease them from mixing separates fluids or fluids are allowed in direct contact with each other. The exact goals of this job were to select the most satisfying materials, designs, and optimize manufacturing processes.. After fabrication, man or woman diagram idea prototypes had been examined to decide their thermal performance. Materials like SS304+Flyash and SS316+Cu are used as composites alloys for fabrication of CHE
