“…Thus, the foam system becomes unstable. The cells can gradually stop forming and growing through cooling or long-term cooling storage, finally providing the foamed polymer. , Many researches have described the process in detail; , thus, in this section, we mainly summarize the common strategies for preparing PA foams, including physical foaming and chemical foaming processes. Meanwhile, FAs, the core in the preparation of foaming materials, can generate gas or accelerate gas production, thereby helping materials to form porous structures during processing.…”

Polyamide (PA) foams have been widely applied in many areas due to their outstanding properties and currently are receiving more extensive attention from the fundamental research and materials communities. However, poor melt strength and low matrix modulus seriously affect the preparation of high-performance PA foams and hinder their commercialization process. To overcome the limitations, a lot of efforts have been devoted to the research subject. In spite of the striking progress made dealing with PA foams, there has been no review to summarize the studies yet. This review begins with the consideration of the foaming process of PA and commonly used methods for PA foaming. Special emphasis is placed on effective means to enhance the performance of PA foams. Then, the typical applications of PA foams are presented, such as flame retardant, oil spill cleaning, electromagnetic shielding, and tissue engineering. Finally, the future perspective of PA foams will be outlined as well as the recommended future research directions about them.

“…On the other hand, the research on new polyamide elastomer foam materials is still at its preliminary stage in the world. Although there are several brands of polyamide elastomers that have been used to prepare foam materials, the entire family of polyamide elastomers is too few and a wide range of polyamide elastomer foam materials are still required 29–32 . Based on the success in preparation of polyamide‐1012 and the introduction of polytetrahydrofuran (PTMG) soft segments, our group prepared a very soft polyamide elastomer with Shore hardness of 20D.…”

Thermoplastic polyamide elastomer (TPAE) is a kind of high‐performance elastomers prepared from nylon hard segments and polyether or polyester soft segments. The hard segments endow TPAE with excellent mechanical properties, while the soft segments provide the desired elasticity. Therefore, the development of TPAE as a high‐performance foam material has broad application prospects. In this work, ethylene‐vinyl acetate copolymer/polyamide‐1012 elastomer (EVA/TPAE1012) composite materials with different compositions were prepared, using ethylene‐vinyl acetate /maleic anhydride graft copolymer (EVA‐g‐MAH) as compatibilizer. Then, EVA/TPAE foamed materials were fabricated by chemical foaming method and batch foaming process, with azodicarbonamide as blowing agent. The resulting composite foams were tested in terms of density, cell properties hardness, resilience, compression recovery, and mechanical strength. The EVA/TPAE1012 foam has a low density (0.14 g cm−3), small cell size (approximately 62.1 μm), and a high cell density (3.08 × 107 cells cm−3). Compared with pure EVA foam, the composite foam not only has an increase in specific strength, resilience and tearing strength, but also has good toughness, which greatly improves the resulting foams' expansion ratio and elongation at break.

“…Recently, the excellent properties of thermoplastic polyamide elastomer (TPAE) have aroused many scholars’ research interest. 33–37 Compared to TPU or other elastomers mentioned above, TPAE not only has better mechanical properties, such as tensile strength, elastic modulus, and notched impact strength, but also has better thermal stability. Therefore, it can be used to improve the impact strength and flexibility at a high or low temperature of other polymers, such as PBT, PET, POM, and so on.…”

Polyoxymethylene/thermoplastic polyamide elastomer (POM/TPAE) blends were prepared through melt extrusion in an attempt to improve the toughness and electrical properties of POM. The TPAE used in the study had the permanent antistatic effect, and its brand was MV2080. Acrylonitrile-butadiene-styrene copolymer grafted maleic anhydride (ABS-g-MAH) was added while preparing the POM/TPAE blends to improve the compatibility between TPAE and POM. The effects of TPAE and ABS-g-MAH on the morphologies, melting crystallization, dynamic mechanical analysis, surface resistivity and mechanical properties were examined in detail with various techniques. It was found that after adding 15 phr MV2080 as the modifier, the distribution of MV2080 in the blends was presented as many continuous long strips, which can be called “antistatic networks.” When using ABS-g-MAH as a compatibilizer, the surface resistivity of the samples 5#, 6#, and 7# which all containing 15 phr MV2080 with the best antistatic properties reached 107 Ω, and the impact strength of the above samples was all increased by more than 66%.
