“…This torque increase is a direct indication of an increased composite shear modulus due to the interaction of nanoparticles, which in turn increases the rigidity of the vulcanizates. 8,32 Interestingly, the relative magnitude of the torque values is in the descending order, ENR1.5 > ENR3 ∼ ENR5 > ENR0.5 > ENR0. As seen in the inset figure, there is not much difference in the torque values for ENR3 and ENR5.…”

“…Polar functional groups present in a polymer are well known to play a major role in enhancing the interaction between nanoparticles and an elastomeric matrix. 8 Epoxide natural rubber (ENR) is a polar polymer used for preparation of rubber nanocomposites due to its good interaction with polar nanoparticles. 9–11 Partially vulcanized ENR properties such as hardness, oil and solvent resistance, gas permeability, rolling resistance, and wet grip were improved over those of natural rubber.…”

Many researchers have been trying to improve rubber composites because they are commonly used in a wide range of applications. Incorporation of nano-fillers in a rubber matrix is the most acceptable way to improve the mechanical and electrical properties of rubber composites. A nanometer-sized filler, such as K0.15Cr0.02Ni0.83O (KCNO), has rarely been used to improve the properties of rubber composites. Epoxidized natural rubber (ENR) was chosen for blending with KCNO nanoparticles based on its polarity and chemical resistance. The aim of this work is to investigate the effects of filler loading (0.5, 1.5, and 5 phr) on the curing characteristics, dynamic mechanical, mechanical, morphological, and dielectric properties of rubber composites. From the results, rubber vulcanizates with 1.5 phr of KCNO as filler exhibit better tensile strength and 500% modulus compared to other ENR specimens containing KCNO. ENR containing 1.5 phr of KCNO also has a higher storage modulus (E′) and glass transition temperature (Tg). The results of a microstructural characterization on a sample containing 1.5 phr of KCNO show that the natural rubber matrix and KCNO are effectively dispersed, indicating that the rubber and KCNO are likely well-matched, therefore curing simultaneously and forming a continuous phase. Furthermore, ENR containing 1.5 phr of KCNO has a greater dielectric constant (12.87 at 5 kHz) than other samples.

The reaction of p-carboxy phenyl amino maleimide (CHM) with cellulose acetate (CA), led to the formation of a modified cellulose acetate polymer (MCA), which was characterized by UV/Vis, 1H NMR, and 13C NMR. The active sites of the reaction were the –NH group of (CHM) and the OAc of CA. CA was grafted with (CHM) to build branches on its main chains, using benzoyl peroxide as an initiator. The results of 1H NMR and 13C NMR revealed the presence of (CHM) moieties inside the polymeric matrix. The (CA-g-CHM) ZrO2 was fabricated into a membrane, using a phase inversion technique. The effect of ZrO2 content on the water flux was discussed. The SEM/EDS was also used to characterize the membrane contents and morphology. The morphology of the membrane showed the grafted parts and the EDS confirmed the presence of nitrogen atoms in the polymeric matrix. The thermogravimetry (TGA) results showed that the membrane exhibited high thermal stability which would adjust the membrane for the desalination process. The desalination test indicated the removal of NaCl salt by the membrane, as shown by the EDS and 1H NMR spectroscopy results. The membrane exhibited good antibacterial and antifungal properties.
