“…Flyash is a fine ash byproduct commonly produced by the combustion of coal during the generation of electrical power. The results of many experimental studies conducted with flyash have shown that the addition of flyash filler does increase the stiffness of a plastic formulation, but like most fillers, reduces impact resistance 17–26. Chand18 introduced flyash into thermosetting polyesters and found that the impact strength and the ultimate tensile strength decreased with the addition of the flyash.…”

Fillers are used along with various commodity as well as engineering polymers to improve the properties of polymers. The performance of filled polymers is generally decided on the basis of the interface attraction of filler and polymers. Fillers of widely varying particle size and surface characteristics are responsive to the interfacial interactions with polymers. The present study deals with the effect of a coupling agent, tetra isopropyl titanate (TPT), on the properties of flyash filled nylon 6. It is observed that tensile strength, impact strength, and heat distortion temperature improved with the addition of TPT as compared to without the coupling agent filled nylon 6.

“…The storage and disposal of coal fly ash, designed to avoid environmental pollution, have become a worldwide problem, and the reuse of fly ash is becoming increasingly important. During the last few decades, the wide use of fly ash has been studied by many researchers, and fly ash has been used in many areas, such as cement and concrete applications, brick, ceramic tile, light‐weight aggregates, highway pavement, road bases, subgrades, and backfills 1–3. Most of these are low‐added‐value uses.…”

“…Polymers filled with fly ash have been investigated by a numbers of researchers,2, 7, 8, 11 but so far, not much work has been reported on the use of plerospheres as fillers for polymers. Chand7 introduced fly ash into a thermosetting polyester and found that the impact strength and ultimate tensile strength decreased with the addition of fly ash.…”

Plerospheres, defined here as superfine spherical particles (0.5-5 m) separated from fly ash (rather than as other solid spherical particles, as some have used the term), are separated from coal fly ash but are dramatically different from it. Plerospheres can be used as polymer fillers to improve the properties of composites. With plerospheres used as fillers for polypropylene (PP) and unplasticized poly(vinyl chloride) (UPVC), the effects of the filler content, the particle sizes of the plerospheres, and the coupling agent on the composite properties were studied. The particle sizes of the plerospheres were 2 and 5 m. The results suggested that the notched impact properties both at a normal temperature and a low temperature and the tensile and flexural properties of plerosphere/PP increased significantly when the content was increased from 0 to 30 wt % and further increased with the addition of a coupling agent. Differential scanning calorimetry indicated that the thermal properties of the plerosphere/PP composite improved. The surface characteristics and morphology of the impact fracture surface were examined in detail with scanning electron microscopy. The rheological performance of plerosphere/UPVC pipe composites obviously improved; the plasticizing time was shortened, and the maximum torque was reduced.

“…3,4 Therefore, the good dispersion of nanollers in a polymer matrix is required to fabricate the thermal properties of a PC/FAC composite for electronic operable applications. 6 In general, the major chemical components of cenosphere comprises silicon, aluminum, and iron, whose precise concentration varies in the range of 50-65 wt% SiO 2 , 20-37% Al 2 O 3 and 1-11 wt% Fe 2 O 3 . These are usually incorporated in metals, ceramics and polymer matrices for producing low cost composite materials and coating foams for industrial applications.…”

The configuration of thin film polycarbonate (PC) is formulated, aiming for a financially efficient approach of the solvent casting method by grafting waste fly ash cenosphere (FAC) encapsulated with tetraethoxysilane (TEOS) as a grafting agent. The research study emphasized on the routine practice of controlled thermal dissipative electronic widgets by a systematic characterization analysis. FTIR exemplifies the surface adherence characteristics of the GFAC (Grafted Fly Ash Cenosphere) over PC, by confirming the efficient grafting between silane and FAC at 2950 cm À1 due to the flexible vibrations by the -OH group. The PC-FAC composite showed the characteristic triplet signature peaks of PC at 1152, 1188 and 1227 cm À1 .Following the hierarchy, the morphological study analyzes the surface molecular interaction between the PC/GFAC and their electronic properties by FESEM. AFM confers the topographical study of pristine PC, which measures the surface roughness of pristine PC as 4.5 nm which mitigates to 0.7 nm for the PC/GFAC and justifies the homogenous dispersion of GFAC in PC, thus directing the consequential study of TGA. It examines controlled surface thermal conduction and authenticates the noble thermal stability of the PC/GFAC with a char yield of 36% (approximately more than twice that of pristine PC) at 800 C by TGA. The PC/GFAC affirms a 70 C lag in the onset of thermal degradation, at 430 C, as compared with pristine PC, which starts to decompose at 360 C. Thus, the silane grafted nano composites of PC expands the operable temperature range for the electronic elemental properties usage. The present investigation procures attention on the thermal characteristics of the PC/GFAC, illustrated by the conduction modeling parameter across the spherical wall of the cenosphere and the interfacial heat transfer for the PC/GFAC composite, pertaining to a worthwhile and serviceable thermal management praxis.
