“…The resulting porous PA materials exhibited low thermal conductivity, high crystallinity, and good mechanical properties (Table 2). Ramya et al [24] synthesized novel regenerable 13X zeolite-PI adsorbent foams. Their results indicated that isocyanate reacts with distilled water to produce CO 2 and a primary amine to create pores in the foam during the blowing reaction.…”

“…Thereby, isocyanate reacts with water to produce CO 2 and primary amines that create pores in the foam during the release of CO 2 within the mixture of PI precursor and zeolite. [171] The blowing process allows for the direct incorporation of large amounts of copper and nickel micrometer-sized particles into the PI foams. [172] In the course of this, it is important to accurately adjust the amount of water and solvent to prevent the open cell porous structure from collapsing.…”

Particulate and gaseous air pollutants pose a threat to human health and contribute to climate change. By today, air filters, stationary and portable, are markedly improved and can often provide innocuous air pollution levels. After introducing the classification and standards on air filters, the influence of the processing route and its parameters on the resulting air filter properties and consequently its performance are discussed. Numerous tools are presented to adjust structural properties such as fiber or pore diameter, specific surface area, surface charge, hydrophilicity, or photocatalytic activity to achieve the desired performance in terms of high filtration efficiencies, sufficient mechanical stability, regeneration eligibility, antimicrobial and optical properties. In particular, inorganic and composite materials as well as nonfibrous structures are covered, which are currently holding an outsider position in an air filter community dominated by polymeric materials and fibrous structures.

“…Presently, a majority of studies have been conducted to fabricate multifunctional PIFs. − For example, hydrophobic PIFs can be prepared with the introduction of components containing fluorine element. , Song et al reported that the glass transition temperature ( T g ) of PIs can be significantly improved with the presence of benzimidazole moieties in the chain structure . In addition, PIFs with excellent electrical conductivity, electromagnetic interference shielding, and fire retardancy performance can be obtained with the addition of multifunctional additives such as graphene, carbon nanotubes, MXene, and so forth. − However, the relationship between chain structure, rheological behavior of PEAS, and the morphology of foam cells is always neglected.…”

This work focuses on the influence of chain structure on properties such as the structural, thermal, morphological, and mechanical properties of polyimide foams (PIFs) which were prepared by polyester ammonium salt powder foaming process. Results showed that the melt viscosity of PEAS is affected by the structure of dianhydrides, which can greatly determine the foaming process, cell structure, and final properties of PIFs. PIF which was derived from 3,3′,4,4′-benzophenonetetracarboxylic dianhydride and 4,4′-diaminodiphenylmethane exhibited the highest compressive strength (0.374 MPa-RT, 0.194 MPa-200 °C) and compressive modulus (9.24 MPa-RT, 7.37 MPa-200 °C). All PIFs exhibited excellent thermal stability as the initial thermal decomposition temperature reached as high as 544 °C. In addition, the thermal conductivity of the as-prepared PIFs fell in a range of 38−42 mW m −1 K −1 , which show potential applications in areas of aerospace, aeronautics, marine use, and transportation among others.
