Characterization and morphological study of biodegradable PVA-Gelatin/CNT composite foams prepared via high-pressure batch foaming method

Magnetite-sepiolite nanoarchitectonics for improving zein-based bionanocomposite foams

“…Although the lack of standardized testing methods for different sources or for specific applications makes it difficult to compare the performance of foam-based bionanocomposite materials, some characteristics of the zein foams prepared here make them very advantageous in different aspects. In this sense, it is relevant to mention the easy processing without the need of supercritical carbon dioxide and the subsequent sudden expansion, 55,56 or high-pressure batch foaming method 57 as required for other polymer materials. The prepared zein foams do not need any stabilizers or emulsifiers in its composition, such as sorbitan monostearate, 58 becoming an attractive final material due to the use of more sustainable precursors.…”

Fabricating of poly(vinyl alcohol)/halloysite nanotubes/gelatin composite sponges with enhanced mechanical properties and rapid water absorption speed

“…5,6 In particular, PVA has been applied to repair injured soft tissues such as cartilage, liver, or kidney tissue 7 due to its benefits of nontoxicity, [8][9][10] flexibility, 11 biocompatibility, and biodegradability. 12,13 Nevertheless, the practical application of PVA is restricted by its inadequate mechanical properties, insufficient water absorption, and slow water absorption rate, which limit the practical application of PVA. 14,15 Introducing nanofillers into the PVA matrix was considered as an effective method to enhance the mechanical performance, [16][17][18][19] such as graphene oxide, [20][21][22] CuO nanofillers, 23 sodium alginate nanofibers, 24 and porous boron nitride nanofibers.…”

“…It can be used in vascular cell culture, vascular implantation, and corneal implants 2–4 as a biomedical material 5,6 . In particular, PVA has been applied to repair injured soft tissues such as cartilage, liver, or kidney tissue 7 due to its benefits of nontoxicity, 8–10 flexibility, 11 biocompatibility, and biodegradability 12,13 . Nevertheless, the practical application of PVA is restricted by its inadequate mechanical properties, insufficient water absorption, and slow water absorption rate, which limit the practical application of PVA 14,15 …”
