“…Elastic modulus is one of the most important mechanical predictions parameter for making the structural analysis and design of the materials and a measure of the interatomic bonds force [27]. As can be seen from the graph, while pure polymer has the lowest elastic module value with 5.3 MPa, the Young's modulus values obtained with adding TiO 2 to pure polymer increase approximately 10-fold.…”

In this study, phthalimide derived polymer-TiO2 nanocomposites were prepared by direct mixing method and their mechanical properties were compared. The high content filler polymer nanocomposites with sufficient interface bonding with the polymer matrix have been prepared to maximize the properties of the filler. In the direct mixing method, the polymer obtained by free radical polymerization of the monomer was mixed with TiO2 in high weight percentages. The pulse-echo method was used to characterize the elastic constants of the polymer and polymer-TiO2 nanocomposites through detection of the ultrasonic waves. Transverse and longitudinal ultrasonic velocities have been used to calculate Young?s modulus of these samples. The ultrasonic velocity and Young?s modulus values of polymer-TiO2 nanocomposites showed a linear relationship with the weight percentage of the polymer, which is due to the strong and effective interaction between the particles resulting from by reinforcing TiO2 to the polymer structure. The clustering that emerged with the increase in the amount of reinforcement in the SEM images became more pronounced and it was observed that pure polymer and TiO2 were homogeneously distributed. The porosity and hardness measurements of the polymer and polymer-TiO2 nanocomposites were examined. The hardness and porosity of the polymer structure approximately increased as the percentage values of TiO2 increased. Moreover, TGA results of polymer nanocomposites obtained by direct mixing showed that the thermal stability increased linearly as the weight ratio increase of TiO2 in comparison with the pure polymer.

“…of SDS is dissolved in distilled water (90 ml), 10 gm. of monomers mixture according to the selected BuA percentage (1, 3 and 5%), were added and well irradiated using 400 watts ultrasonic irradiation as initiation system for different times (5,10 and 15 min) 11 .The consolidate is applied with Sprayer without damaging the very fragile pigments and wood. The condition of the wood was such that it needed to absorb a large amount of consolidation.…”

“…Ultrasonic treatment is one of the most important methods for increasing the gallery interval between silicate layers in nanoclay, which considerably improves their dispersion in polymers. 9,10 In addition, ultrasonic treatment also affects the polymer matrix, resulting in the formation of a material with a new structure and altered properties. 11 Polyvinyl alcohol (PVA) is used in the industrial, commercial, medical, and food sectors to produce many products, such as varnishes, resins, surgical yarns, and food packaging, that are often in contact with food.…”

The structure and thermal characteristics of nanocomposites based on polyvinyl alcohol (PVA) and montmorillonite (MMT) intercalated with polyvinylpyrrolidone were investigated by X-ray diffraction analysis and differential scanning calorimetry. The modification of PVA with intercalated MMT reduces the degree of crystallinity of the resulting nanocomposites but significantly increases their thermal stability. Under ultrasound, the intercalated MMT was completely distributed in a PVA solution and formed a monocrystalline structure. Films based on PVA with modified MMT were cross-linked at 110°C in the presence of 5 wt% acrylic acid and 0.5 wt% Ferrous(II) sulfate as an initiator. The formed films have a homogeneous cross-linked structure.
