Foaming Technology

Epoxy-based shape memory (SM) foams have been produced by solid state foaming. According to this foaming technology, precursors are made by cold compaction of thermosetting powders. Subsequently, precursors foam by heating in an oven. In this study, the SM epoxy powder was mixed with multi-walled carbon nanotubes (MWCNTs) and graphene so as to produce SM composite foams. Two different filling contents were used (0.5 and 1 wt%). In order to study the effect of nano-fillers on SM properties of the epoxy foams, foam compressibility was measured at a temperature higher than the transition temperature of the SM epoxy foam (i.e. the glass transition temperature). Moreover, recovery load was measured after a 50% of memorized strain. Results show the positive effect of the fillers in functional and structural terms.

ABSTRACTThe topic of this study is focused on exposure control measures and working practices to minimize/eliminate potential health, safety, and environmental risks associated with the handling of dry nanoparticles. First, it is shown that a glove box with attached vacuum chamber for material transport and air cleaning is highly effective in minimizing occupational exposure to airborne nanoparticles. Second, the propensity for Baytubes C 150 P multi-walled carbon nanotubes to form airborne particles is found to be very low. The combined results provide useful guidelines for both the selection and the use of an engineering control to minimize/eliminate exposure to airborne carbon nanotubes, and nanoparticles in general.
