“…The physio-chemical parameters of different polymers play a very significant role in defining the properties of the subsequent aerogel. Some important properties of polymers include the surface area of the polymer [76,77], chemical structure [78], porosity, density, polymer solubility, thermal stability [79], and the hydrophilic or hydrophobic nature of any specific polymer. Generally, for synthesising aerogels, biopolymers are mainly considered to be utilised in biomedical applications.…”

The inherent disadvantages of traditional non-flexible aerogels, such as high fragility and moisture sensitivity, severely restrict their applications. To address these issues and make the aerogels efficient, especially for advanced medical applications, different techniques have been used to incorporate flexibility in aerogel materials. In recent years, a great boom in flexible aerogels has been observed, which has enabled them to be used in high-tech biomedical applications. The current study comprises a comprehensive review of the preparation techniques of pure polymeric-based hybrid and single-component aerogels and their use in biomedical applications. The biomedical applications of these hybrid aerogels will also be reviewed and discussed, where the flexible polymeric components in the aerogels provide the main contribution. The combination of highly controlled porosity, large internal surfaces, flexibility, and the ability to conform into 3D interconnected structures support versatile properties, which are required for numerous potential medical applications such as tissue engineering; drug delivery reservoir systems; biomedical implants like heart stents, pacemakers, and artificial heart valves; disease diagnosis; and the development of antibacterial materials. The present review also explores the different mechanical, chemical, and physical properties in numerical values, which are most wanted for the fabrication of different materials used in the biomedical fields.

“…Aerogels are formed by replacing the liquid component in the gel hole with a gas and are recognized as the lightest solid materials in the world. As porous materials, aerogels have high porosity and surface area, low density, and thermal conductivity. − These characteristics lead to their widespread use in catalyst carriers, sensors, absorbers, and aerospace materials. Aerogels derived from polymer materials exhibit excellent mechanical properties, thermal insulation properties, and environmental stability, allowing for their use in temperature sensing and fire safety. − If the aerogel is endowed with luminescence properties, the aerogel will have unique optical self-monitoring and tracer functions. , Considering the unique advantage that room-temperature phosphorescent (RTP) materials can continue to glow after the excitation light stops, their introduction into the aerogel system will not only provide a new research direction for the construction of aerogels with optical detection and tracer function but also effectively expand the macroscopic morphology and application range of RTP materials.…”

Exploring the applicability of next-generation pure organic room-temperature phosphorescent (RTP) materials has become a research focus in recent years. Herein, a simple strategy for preparing a long-lived polymer aerogel temperature sensor with an ordered structure as well as thermal insulation was presented. Based on the noncovalent interactions between poly(vinyl alcohol) (PVA) and melamine formaldehyde (MF), a composite aerogel (PVA-MF) with excellent thermal stability, extremely low thermal conductivity, outstanding fire safety, and favorable mechanical strength was constructed. At the same time, PVA-MF aerogels doped with a series of organic phosphorescent small molecules exhibit stable multicolor long-lasting afterglow. In addition, the biphenyl 4-carboxylic acid (BPA)-doped PVA-MF aerogel also showed enduring water-resistant stability. Surprisingly, after repeated heating and cooling cycles, the on–off recording via a reversible temperature response of a continuous RTP signal was realized. Therefore, the aerogel with phosphorescent self-monitoring and tracer function not only promoted the development of aerogel phosphorescent materials but also expanded the application of RTP materials in temperature sensors.
