Structure, permeability, and rheology of supercritical CO2 dispersed polystyrene-clay nanocomposites

Large scale formation of various highly oriented structures in polyethylene/polycarbonate microfibril blends subjected to secondary melt flow

“…In order to further examine the crystalline structures in GAIM microfibril blend containing hybrid shish-kebabs, transcrystallinity and typical shish-kebab superstructures, the long period is calculated using the Bragg equation, L ¼ 2p/q, where L is the long period, and q is the peak position in the scattering curves [47]. Fig.…”

Oxygen Permeability Coefficient of High Density Polyethylene/Cu Nanofibers Nanocomposites below Percolation

“…It was also found that barrier to gas properties of the polymer composites can be enhanced (i.e. the values of the permeability to gas coefficient reduce as percentage of fiber contents increases) as documented in the literature [17][18][19][20][21][22][23][24][25][26][27] . One important key factor that enhances mechanical properties of the polymer is the aspect ratio of the fillers (i.e.…”

Hyper-branched polymer grafting graphene oxide as an effective flame retardant and smoke suppressant for polystyrene

“…[1,2] However, the fire hazard of PS restricts its application in some fields, due to the release of a large amount of heat and toxic smoke during combustion, which will lead to heavy casualties and property losses in case of fire accidents. [3][4][5] Therefore, reducing the fire hazard of PS is an urgent requirement to arouse wide concerns.…”
