The natural rubber (NR) nanocomposites were fabricated by filling ionic liquid (1-allyl-3-methyl-imidazolium chloride, AMI) modified nano-silica (nSiO 2 ) in NR matrix through mechanical mixing and followed by a cure process. Based on the measurements of differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), solid state nuclear magnetic resonance spectroscopy, and Raman spectroscopy, it was proved that AMI could interact with nSiO 2 through hydrogen bonds. With the increase of AMI content, the curing rate of nSiO 2 /NR increased. The results of bound rubber and dynamic mechanical properties showed that polymer-filler interaction increased with the modification of nSiO 2 . Morphology studies revealed that modification of nSiO 2 resulted in a homogenous dispersion of nSiO 2 in NR matrix. AMI modified nSiO 2 could greatly enhance the tensile strength and tear strength of nSiO 2 /NR nanocomposites. Compared to unmodified nSiO 2 /NR nanocomposite, the tensile strength of AMI modified nSiO 2 /NR nanocomposite increased by 102%.

The production of a new class of plastics with improved properties can be achieved through polymer blends rather than using individual components. This study involved the preparation of nanocomposites using melt compounding, where ternary blends comprising natural rubber (NR), styrene-butadiene rubber (SBR), and acrylonitrile rubber (NBR) were combined with nanosilica (NS). In the present study, silica nanoparticles (NS) were prepared from rice husk ash to be utilized as a nanofiller in rubber nanocomposites. Subsequently, the study investigated the mechanical properties of these ternary NR/SBR/NBR blend nanocomposites. Throughout the study, the NR/SBR/NBR content remained constant at 30/30/40 phr, and an ultrablend 4000 at 3 phr was used as a compatibilizer, while varying the fractions of nanosilica. The study's results demonstrated that introducing nanofillers led to a notable enhancement in the stability of both scorch time and the optimal cure time of the nanocomposites. Moreover, the nanosilica content was directly proportional to the increase in tensile strength, stress at 100% elongation, elongation at break %, abrasion resistance, and compression set of the nanocomposites. However, the mole percent uptake exhibited a noteworthy decrease as the nanosilica content increased. Further analysis using FESEM of the tensile fracture surfaces revealed that the inclusion of nanosilica in the nanocomposites led to better adhesion of NR/SBR/NBR rubber and enhanced tensile properties. This study demonstrates the potential of utilizing nanocomposites in polymer blends to enhance the overall performance of elastomers.
