Effects of foaming agent on properties of foamed gel [PDF]
Advanced Composites Letters, 2020 To improve foam expansion and the stability of the foamed gel selected as the starting point, three foaming agents with relatively higher foam expansion and three foam stabilizers were used to determine optimum gradient and composition of the gel. Sodium

Frog nest foams exhibit pharmaceutical foam-like properties [PDF]
Royal Society Open Science, 2021 AbstractFoams have frequently been used as systems for the delivery of cosmetic and therapeutic molecules; however, there is high variability in the foamability and long-term stability of synthetic foams. The development of pharmaceutical foams that exhibit desirable foaming properties, delivering appropriate amounts of the active pharmaceutical ...

Study on Cellular Structure and Mechanical Property of Foaming/Cross-linking Polyethylene System [PDF]
E3S Web of Conferences, 2020 The cellular structure and mechanical property of a sequential foaming/cross-linking polyethylene system were studied in this work. By adjusting the components, foaming starts before the cross-linking reaction initiated and the melt strength increases ...

Hydrogel foams from liquid foam templates: Properties and optimisation
Advances in Colloid and Interface Science, 2021 Hydrogel foams are an important sub-class of macroporous hydrogels. They are commonly obtained by integrating closely-packed gas bubbles of 10-1000 μm into a continuous hydrogel network, leading to gas volume fractions of more than 70% in the wet state and close to 100% in the dried state.

Foaming Behaviour, Structure, and Properties of Polypropylene Nanocomposites Foams [PDF]
Journal of Nanomaterials, 2010 This work presents the preparation and characterization of compression‐moulded montmorillonite and carbon nanofibre‐polypropylene foams. The influence of these nanofillers on the foaming behaviour was analyzed in terms of the foaming parameters and final cellular structure and morphology of the foams.
