The effect of silica polymorphs on the thermomechanical properties of 0, 5, 10, and 20 wt % silica particles-reinforced-based poly(ethylene glycol) (PEG) composites have been studied as a function of temperature using dynamic mechanical analysis (DMA). The silica polymorphs exhibited quartz (Q), cristobalite (C), and amorphous (A) phases, which were obtained by processing natural silica sand. The DMA thermomechanical properties were determined in tensile (E) and shear (G) modes. The maximum storage moduli (E 0 and G 0 ) were achieved by samples with 20 wt % silica for all type of fillers. These values increased approximately 12 times for PEG/Q, 10 times for PEG/A, and 11 times for PEG/C composites compared to the pure PEG. Furthermore, the Poisson's ratio values of the composites were filler phase dependent, that is, 0.39-0.47 for PEG/Q, 0.15-0.18 for PEG/A, and somewhat anomalous for PEG/C composites.

“…There is no significant difference in the functional groups of NRF [ 7 , 23 ]. There is almost no difference for the NRF with charcoal loading due to carbonization at high temperatures, which causes the charcoal powder to exhibit a hydrophobic nature [ 24 ]. However, there is a band growing at 1100 cm −1 for the NRF filled with silica.…”

Natural rubber foam (NRF) can be prepared from concentrated natural latex, providing specific characteristics such as density, compression strength, compression set, and so on, suitable for making shape-memory products. However, many customers require NRF products with a low compression set. This study aims to develop and prepare NRF to investigate its recoverability and other related characteristics by the addition of charcoal and silica fillers. The results showed that increasing filler loading increases physical and mechanical properties. The recoverability of NRF improves as silica increases, contrary to charcoal loading, due to the higher specific surface area of silica. Thermodynamic aspects showed that increasing filler loading increases the compression force (F) as well as the proportion of internal energy to the compression force (Fu/F). The entropy (S) also increases with increasing filler loading, which is favorable for thermodynamic systems. The activation enthalpy (∆Ha) of the NRF with silica is higher than the control NRF, which is due to rubber–filler interactions created within the NRF. A thermodynamic concept of crosslinked rubber foam with filler is proposed. From theory to application, in this study, the NRF has better recoverability with silica loading.

“…Furthermore, the obtained results from this analysis show the increasing char yield via the addition of CGFS‐S3 content, so that the CGFS‐S3–50 sample shows 39.18% char yield compared with only 1.11% for neat LDPE. These results clearly reveal that, with the addition of CGFS‐S3, the thermal‐oxidative stability of the LDPE composites is reinforced …”

“…Carbon black is an important reinforcing filler due to its superior polymer–filler interaction, large surface area, and better surface activity . Silica is also used as a reinforcing filler owing to its fine particle size, toughness, abrasion resistance, and storage modulus . Some other inorganic materials including montmorillonite, lignin, cellulose fiber, silica, calcium carbonate, and magnesium hydroxide have also been studied as the reinforcing filler for polymer .…”

Coal gasification fine slag (CGFS) was processed via a grading technique. The CGFS products (CGFS-S1, CGFS-S2, CGFS-S3) with different sizes were obtained. Effects of particle size and unburned carbon on tensile properties of filled low density polyethylene (LDPE) were studied within the CGFS weight fractions ranging from 10 to 50 wt %. The tensile strength was found to increase with decreasing CGFS size, and the tensile properties exhibited good performance, owing to unburned carbon. The tensile strength of the composites increased with increasing CGFS-S3 weight fraction. The analysis of mathematical model and SEM revealed that the firm improvement of tensile strength resulted from the strong interactions between LDPE polymer chains and CGFS-S3 particles, and good dispersion of CGFS-S3 in resin. Thermogravimetric analysis proved obvious reinforcement in thermal-oxidative stability by incorporation of CGFS-S3. The degree of crystallinity of LDPE/CGFS-S3 showed the first increased and then decreased variation tendency.
