Formation of Porous Epoxy Micro-beads from a Single Droplet of Epoxy-Polyamide-Ammonium Bicarbonate at Different Temperatures

Abstract: Process temperature greatly affects the decomposition behavior of a blowing agent, and changes the structure of the porous epoxy. This paper investigates the effect of processing temperature on the decomposition rate and volume of decomposing gases from ammonium bicarbonate as well as the properties of porous epoxy micro-bead through a single epoxy droplet. A single epoxy droplet (epoxy-polyamide-ammonium bicarbonate) was dropped into the corn oil heated at the temperatures of 80°C, 90°C and 100°C. This study … Show more

“…The most common techniques for fabricating porous microbead are based on immiscibility of resin materials and a medium phase, such as epoxy in water [20] and epoxy in oil [21]. The porous beads are formed by an emulsification technique or a dropping technique [22]. Conductive material such as carbon black can be added to produce conductive epoxy porous beads [23,24].…”

“…In this technique, chemical blowing agents are used, and the foaming process is initiated in the resin state or in the early cured state. Therefore, the technique is highly dependent on the decomposition temperature of the blowing agents (such as TSH, sodium bicarbonates or ammonium bicarbonates) [22][23][24]. Fusion of these porous microbeads is not possible because they are fully cured, and an epoxy binder is needed to act as a matrix and to form the product shape.…”
