“…These nanofiber membranes' ability to capture MB dye from aqueous medium was also tested. The created nanofiber membrane could absorb 95.1% of the MB after 36 min of contact time, and the composition was still stable after five removals, with a performance of about 90.1% for the 0.8Cu-MNPs-GO@PCL [105].…”

Biodegradable poly(ɛ-caprolactone) (PCL) and its composites or blends have received a lot of attention in the last decade because of their potential applications in human life and environmental remediation. Greater efforts have been made to develop biodegradable chemical materials as adsorbents that do not pollute the environment in order to replace traditional materials. Among the numerous types of degradable materials, PCL is currently the most promising, the most popular, and the best material to be developed, and it is referred to as a “green” eco-friendly material. Membranes and adsorbents for water treatment, packaging and compost bags, controlled drug carriers, and biomaterials for tissues such as bone, cartilage, ligament, skeletal muscle, skin, cardiovascular and nerve tissues are just some of the applications of this biodegradable polymer (PCL). The goal of this review is to present a brief overview of PCL, syntheses of PCL, its properties, PCL composites, and PCL blends and to provide a detailed investigation into the utility of PCL/PCL-based adsorbing agents in the removal of dyes/heavy metal ions. Overall, it can be confirmed that PCL blends and composites were found to be significant competitors to other well-known adsorbents in the treatment of wastewaters, necessitating a thorough investigation of their manufacture.

“…These electrospun nanofibers and nanofibrous films have the potential to be used in a wide variety of applications, including cosmetics, sensors, filters, pharmaceutics, and medical cloth 17–19 . Relying on regulating the parameters used in the electrospinning process, various nanofibrous structures can be generated, such as nonwoven films, uniaxial arrays, and single nanofibers 20–28 . NPs of rare‐earth activated aluminate phosphors have recently attracted a great interest owing to their usefulness in a number of different fields.…”

Photochromism has been used as an attractive method to enhance the authentication of commercially available goods. It has been fundamental to enhance the engineering procedure of the authentication materials to introduce a mechanically reliable authentication nanofibrous film. In this context, we develop a mechanically reliable and photoluminescent electrospun nanofibrous polycarbonate film immobilized with lanthanide‐doped aluminate nanoparticles (NPs) by the electrospinning method for authentication purposes. The prepared composite film displayed photochromism by changing color from transparent under daytime light to green under ultraviolet light. To guarantee the transparency of the electrospun nanofibrous film, the strontium aluminate pigment must be presented in the nano‐scaled particle form to improve its distribution without forming aggregates in the electrospun polycarbonate nanofibrous bulk. The pigment‐polycarbonate nanofibers showed an emission band at 512 nm upon excitation at 374 nm. The pigment‐polycarbonate nanofibers showed an improved hydrophobicity with raising the pigment ratio without adverse influences on their inherent appearance and mechanical characteristics. When excited with UV light, the transparent films had rapid and reversible photochromism without fatigue. The nanofibrous mats displayed elasticity and flexibility. The present approach can be described as a competent method for the preparation of diverse anticounterfeiting materials.

“…[23] In addition, the functional groups provoke GO to show hydrophilic behaviour. [27,28] GO is formed as sheets within the nanocomposite, which could increase its antibacterial effect due to the marked effectiveness of the sharp edges on bacteria that can produce physical damage. [29] In addition, GO has the ability to produce reactive oxygen species (ROS), this is regarded as a chemical approach to treating bacterial growth.…”

Designing a nanocomposite that accumulates biocompatibility and antimicrobial behaviour is an essential requirement for biomedical applications. Hydroxyapatite (HAP), graphene oxide, and vivianite in one ternary nanocomposite with three phases and shapes led to an increase in cell viability to 97.6% ± 4 for the osteoblast cells in vitro. The obtained nanocomposites were investigated for their structural features using X-ray diffraction, while the microstructure features were analyzed using a scanning electron microscope (SEM) and a transmission electron microscope. The analysis showed a decrease in the crystal size to 13 nm, while the HAP grains reached 30 nm.The elongated shape of vivianite reached 200 nm on SEM micrographs. The monoclinic and hexagonal crystal systems of HAP and vivianite were presented in the ternary nanocomposite. The maximum roughness peak height reached 236.1 nm for the ternary nanocomposite from 203.3 nm, while the maximum height of the roughness parameter reached 440.7 nm for the di-nanocomposite of HAP/graphene oxide from 419.7 nm. The corrosion current density reached 0.004 μA/cm 2 . The ferrous (Fe 2+ ) and calcium (Ca 2+ ) ions released were measured and confirmed. Therefore, the morphology of the nanocomposites affected bacterial activity. This was estimated as an inhibition zone and reached 14.5 ± 0.9 and 13.4 ± 1.1 mm for Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) after 24 h. The increase in viability and the antibacterial activity refer to the compatibility of the nanocomposite in different medical applications.
