As the problem of bacterial contamination continues to grow in its significance, researchers have reported many antibacterial materials that are based on inorganic compounds. Of these, materials that are based on silica and its derivatives have been widely used in engineering, medicine, and food. This paper reviews the advantages, safety issues, and applications of silica and its derivatives, as reported in recent years. The information provided highlights the preparation, application, and antimicrobial efficiency of materials that are based on silica and have different structure/size. We outline the possible antimicrobial mechanisms of silica‐based materials and the potential challenges that researchers may face. With a focus on increasing concerns regarding bacterial contamination in the food and medical industries, we have also proposed corresponding antibacterial material preparation strategies.

“…Polymers such as silicones offer enhanced and prolonged hydrophobicity and therefore lower operating costs, in addition to a greener manufacturing footprint . Silicone insulators are also suitable for a wide variety of climates, including those with extreme temperature variation and those subject to deicing salts in winter conditions. , However, one area that remains particularly challenging is mitigation of algae adhesion when the devices are installed in coastal areas as the fouling of bioorganisms rapidly degrades the material surfaces. − Although some field reports exist, there is a lack of data on algae–silicone interactions, particularly under environmental conditions such as exposure to water and high voltage. Silicone polymers are also widely used in microfluidic devices, including in applications where cells are adhered in a variety of aqueous environments. , …”

Algae Adhesion onto Silicone is Sensitive to Environment-Induced Surface Restructuring

Resistance to algae contamination is an important characteristic of insulators used in overhead power distribution in coastal environments. It is therefore important to understand the parameters governing algae adhesion onto polymer insulator materials such as silicone. Flow cell-based shear experiments were conducted in order to characterize the adhesion strength of algae onto polydimethylsiloxane surfaces, comparing fresh polymer substrates with those that have been soaked in water and saline solutions for 1 month. Both freshwater algae and seawater species could withstand considerably less drag force and were therefore more easily removed when the polymer was soaked in salt water. The polymer surface was found to be unaltered in terms of its roughness, contact angle, and lack of water uptake; no macroscopic surface characterization was therefore able to account for the differences in cell adhesion strength resulting from the soaking treatment. Surface-specific nonlinear vibrational spectroscopy, however, revealed subtle differences in the orientation of surface methyl groups that resulted from the water and saline exposure.

“…The polymeric-based is widely used today as an electrical insulating material. This insulating material has some advantages compared to other materials such as having water repellent properties, thermal properties, and excellent dielectric properties [1][2][3][4], which are characterized by high penetrating stress levels [5][6][7]. Also, polymer materials are lightweight and straightforward in the manufacturing process [8,9].…”

The dielectric properties of low-density polyethylene natural rubber (LDPE-NR) biopolymeric insulating materials can be improved by adding the silica nanoparticles in a certain percentage of weight (w%). In the present study, four types of bio-nano polymeric samples were prepared. To each sample, the nanosilica particles with wt% 1.5%, 3%, 4.5% and 6%. As one characteristic of dielectric, the partial discharge (PD) characteristics, each sample has been tested for 1 hour under AC high voltage field, and the pulses were counted for each sample and grouped into positive and negative pulses. The PD pattern was also plotted based on X-Y axes, namely Φ-q-n pattern. It was found that the number of positive and negative partial discharge (PD) pulses for each silica sample after 60 minutes of testing varied for all samples. It is also found that samples with a higher percentage of nanosilica had fewer PD pulses. The PD pattern in lower w% of silica was identified in the 90 degrees mostly in containing This indicates that w% of nanosilica particles can improve the PD resistance or the insulation quality of LDPE-NR insulation materials.
