“…When this membrane was exposed to bacterial solution, a large number of bacteria adhered to the hydrophilic side of the membrane (PCL/PAA/PEI-CMC), while no bacteria were found on the hydrophobic PCL side. This result demonstrated that the Janus hemostatic membrane was able to resist the invasion of external bacteria and thus prevent wound infection [154].…”

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.

“…Elastic bandages, serving as essential first-aid items, effectively halt bleeding, minimize swelling, and fit well into the human body contour, thereby preventing secondary injury and facilitating recovery. They have been widely used in rehabilitation training, wound healing, , and health care . Recently, with the latest developments in training theory, the ideal bandage is considered to be a porous soft material with directional tensile performance along the length direction that provides fixation pressure to an injured body part without hindering the normal movements of other body parts, i.e., offers comfortable and anisotropic-elastic function .…”

Elastic fabric bandages exhibit great potential in covering the body contours due to their tensile and comfort performance being well-regulated by their fibrous structure. However, achieving low-coast and facile preparation methods for the fabric bandage with directional tensile performance remains a significant challenge. In this work, a cellulose/polyester composite fabric reinforced by polyolefin−elastomer filament webs (CEL/PET@ POE composite fabrics) was developed by a green and commercialized manufacturing strategy involving a laminating, cross-lapping, and needle-punching process. The resultant composited fabrics possess a multilayered fibrous morphology where fibers are aligned at −45°, 0°(along the longitude direction, i.e., length direction of the fabrics), and +45°. Besides, the POE filaments interweave amid the cellulose/polyester fibrous clusters, resulting in a stable network fibrous structure that offers excellent anisotropic elastic performance and directional extension performance. The fabric displays a breaking strength and elongation in the cross direction that are 2.7 and 0.55 times greater, respectively, compared to those in the machine direction. Moreover, the samples demonstrate brilliant breathability, excellent wearing comfort, and outstanding shape ability. These findings suggest that the prepared CEL/PET@POE composite fabric provides a powerful foundation for a series of potential applications in wearable medical hygiene, such as bandages, electronic textiles, and padding materials.

“…Inspired by Collocalia birds’ nest-building technique, Chao et al. introduced a biomimetic Janus-structured bandage, as shown in Figure 6 D. 79 This innovative bandage integrates self-gelling powders with nanofibers to create a dual-function membrane. Its asymmetric wettability features a hydrophilic side for enhancing blood coagulation and a hydrophobic side for antibacterial protection.…”
