Hydrogels are promising biomaterials for diverse applications that require studying their rheological properties. While some properties of hydrogels have been investigated, their comparative analysis for a deeper understanding of their rheological properties is required to determine their mechanical behavior. Polyvinyl alcohol (PVA) and polyethylene glycol (PEG) are among the hydrogels with diverse applications in engineering. This study aims to provide comparative data on their rheological properties. Both PVA and PEG showed steady shear viscosity as their viscosity did not show a huge change with time. Their shear viscosity increased with shear strain. PEG showed more shear thickening behavior than PVA. While the shear viscosity of PVA reached a plateau, that of PEG continued to increase. This was attributed to the sensitivity of PEG to its deformation because of the junction separations after the application of mechanical force on the polymer. Furthermore, the slow increase in the shear viscosity of both polymers was observed with the increase of the shear rate. This increase was 2.4 % for PVA and 8.7 % PEG, respectively. As these polymers are among the candidates for the preparation of nanocomposites, the results of this study can provide the required information for their applications in engineering.

This paper focuses on studying the rheological properties of polydimethylsiloxane (PDMS). This polymer has been used to fabricate membranes and filters in engineering. The analysis of the rheological properties of this polymer is required for a further investigation of its mechanical behavior. In this study, the rheological behavior of PDMS is reported at different temperatures. This polymer showed steady shear viscosity during a short duration. However, this behavior changed with time and increased more with increasing temperature. The impact of the temperature increase was also observed when the shear viscosity of PDMS increased with shear strain. The increase of torque with shear strain and time was observed at different temperatures. Shear stress increased linearly with the shear rate at 20 °C and 40 °C. As expected, the deformation of the polymer required less shear stress with the increase of temperature. However, the change of shear stress with the shear rate at 60 °C was not linear, and the slope of the curve increased more at high shear rates. The results of this investigation can provide the required information for a better fabrication of membranes and filters with this polymer.

The present study focuses on the comparative analysis of superparamagnetic iron oxide nanoparticles (SPIONs) characteristics with the TOPSIS method. The prediction of the characteristics of SPIONs is required for better manufacturing of these nanoparticles. Although the characteristics of these nanoparticles have been investigated, no research has been done on their comparison in order to determine which one of their surface functionalities would be more appropriate for their diverse applications. The objective of this study was to analyze the characteristics of SPIONs without or with surface charge with a prediction model and TOPSIS in order to determine the best nanoparticles. Moreover, the effect of inappropriate consideration of their cost criterion on their ranks was explored with the modified TOPSIS. This analysis showed that the characteristics of SPIONs such as antibiofilm activity, hemocompatibility, activity with hydrogen peroxide, rheological properties, and the labour of their chemical synthesis could affect their ranking. Neutral SPIONs, negatively charged SPIONs, and positively charged SPIONs were ranked as the first, second, and third candidates, respectively. However, the improvement of the activity of positively charged SPIONs with hydrogen peroxide showed an increase to 0.3 instead of 0.2, which resulted in a better rank of these nanoparticles in comparison with that of the same nanoparticles in the first analysis series. One of the advantages of this study was to determine the impact of the characteristics of SPIONs on their ranking for their manufacturing. The other advantage was getting the information for further comparative study of these nanoparticles with the others. The results of this work can be used in manufacturing engineering and materials science.
