Plasma surface treatment of HDPE powder in a fluidized bed reactor

Surface modification of polyethylene powder by nitrogen and ammonia low pressure plasma in a fluidized bed reactor

“…Park and Kim [12] have shown that the O/C atomic ratio and oxygen functionalities increased with the increase of rf power on the surface of HDPE powders with oxygen plasma treatment. The effect of rf power on the nitrogen incorporation for plasma treated LDPE powders in the fluidized bed reactor is shown in Fig.…”

“…A very good contact between reactive species of the plasma discharge and powder surfaces is obtained. In the literature surface treatment of polymer powders in fluidized bed reactor has been reported with oxygen plasmas [12,13] or to perform deposition of organic and inorganic compounds [14,15].…”

Effects of reactive gas on shear and fracture behaviors of plasma-treated polyethylene/steel joints

“…Several methods have been reported to make HDPE more hydrophilic. Currently, plasma treatment is widely used because it can easily create new functional groups that are difficult to obtain by other methods [6][7][8][9]. Plasma treatment of polymer materials is affected by which reactive gas is used for the treatment.…”

Surface Treatment of Polymeric Fine Powders by CF4 Plasma in a Circulating Fluidized Bed Reactor

“…The possibility of altering surface of polymer materials at room temperature and uniqueness of the modified surfaces are particularly appreciated with advantages of low-pressure plasma processing for the surface modification applications (Park and Kim, 1994;Inagaki et al, 1992). Plasma surface modification of polymeric materials has been used to change the chemical composition, control the surface energy, modify the morphology, and surface topography.…”

“…Rotary drums can be used as a reactor with low energy plasma but powder dispersion is not satisfactory (Iriyama and Ikeda, 1994). (3) Fluidized bed reactor: powders are suspended above the minimum fluidizing velocity and the plasma is generated in the upper part of a stationary bed (Inagaki et al, 1992;Matsukata et al, 1994;Park and Kim, 1994. In all cases there are possible uncertainties of gas reactivity gradients and resulting in inhomogeneous treatment of powders (Bayer et al, 1998).…”
