Plasma Surface Treatment

Plant source-based stiff fiber reinforced bioplastics based on natural plant derived substances show promise of providing degradation back into the environment when they are no longer needed. These "green" composites have enormous potential to replace materials originated from non-renewable resources and may turn out to be one of the material revolutions of this century. Unlike synthetic composites, "green" composites are renewable, carbon neutral, biodegradable, non-petroleum based, and have low environmental, human health and safety risks. In this paper effect of pineapple leaf fiber (PALF) length and physical surface treatment on to the properties of the composites was investigated at 10% wt. loading. In order to improve compatibility and composite properties of PALF/poly (lactic acid) composites without any hazardous chemicals that are usually involved in the process, dielectric barrier discharge (DBD) plasma surface treatment was conducted for fiber modification. Therefore more environmentally friendlier and industrially scalable technology was implemented in processing of composites by twin screw extrusion and injection moulding. Resulted composites were characterized by means of scanning electron microscopy (SEM), thermal and mechanical testing.

Plasma Surface Interactions

In this paper, an overview is given of modeling activities going on in our research group, for describing the plasma chemistry and plasma–surface interactions in reactive plasmas. The plasma chemistry is calculated by a fluid approach or by hybrid Monte Carlo (MC)–fluid modeling. An example of both is illustrated in the first part of the paper. The example of fluid modeling is given for a dielectric barrier discharge (DBD) in CH4/O2, to describe the partial oxidation of CH4 into value-added chemicals. The example of hybrid MC–fluid modeling concerns an inductively coupled plasma (ICP) etch reactor in Ar/Cl2/O2, including also the description of the etch process. The second part of the paper deals with the treatment of plasma–surface interactions on the atomic level, with molecular dynamics (MD) simulations or a combination of MD and MC simulations.
