Journal ArticleDOI
Poly(lactic acid) crystallization
TL;DR: An overview of the current understanding on the fundamentals of PLA crystallization in quiescent conditions and on the practical means to enhance its rate can be found in this paper, where the most promising efforts in enhancing PLA crystallisation kinetics through plasticization or heterogeneous nucleation are reviewed.
Journal ArticleDOI
Electrical properties and electromagnetic interference shielding effectiveness of polypropylene/carbon fiber composite foams
TL;DR: In this paper, the effects of foaming on the fibers interconnectivity and orientation, electrical percolation threshold, through-plane electrical conductivity, longitudinal and transversal in-plane conductivities, dielectric permittivity, and electromagnetic interference shielding effectiveness (SE) were investigated.
Journal ArticleDOI
Effect of the pressure drop rate on cell nucleation in continuous processing of microcellular polymers
TL;DR: The experimental results indicate that both the magnitude and the rate of pressure drop play a strong role in microcellular processing.
Journal ArticleDOI
Poly (lactic acid) foaming
Mohammadreza Nofar,Chul B. Park +1 more
TL;DR: In this paper, a review of the developments made thus far in PLA foaming can be found, where the authors have investigated the fundamentals of PLA/gas mixtures, PLA foasting mechanisms, and the effects of material modification on PLA's foaming behavior through various manufacturing technologies.
Journal ArticleDOI
Polypropylene/carbon nanotube nano/microcellular structures with high dielectric permittivity, low dielectric loss, and low percolation threshold
TL;DR: In this paper, the electrical properties of nano-cellular polypropylene/multiwalled carbon nanotube (MWCNT) composites with relative densities ( ρ R ) of 1.0-0.1, cell sizes of 70nm-70μm, and cell densities of 3.0 −10 7 −2 −2 -10 14 cells −3 are reported.
