Plasma treatment is a novel and promising technolgy in the field of wood surface modification. Deposition of micro-particles on wood surfaces by means of plasma is an interesting approach to enhance wood properties and thus, to extend the service life of wood products. On the other hand, several silicone fomulations have been already shown to cause excellent water repellence and interaction with cell wall components, beside to impart high chenical and weathering stability as well as biological resistance in treated wood. Based on that, this study focussed on both treatments seperately in an initial stage of the research; followed by the combination, in a two-step treatment, of vacuum-pressure impregnation of solid wook with siloxanes and additional copper deposition on wood surface using atmostpheric pressure plasma.

The market for durable products using modified wood has increased substantially during the last few years. This is partly because of the restriction on the use of toxic preservatives due to environmental concerns, and to lower maintenance cost and time. Furthermore, as sustainability becomes a greater concern, the environmental impact of construction and interior materials is factored in planning by considering the whole life cycle and embodied energy of the materials used. Wood is modified to improve its intrinsic properties, enhance the range of applications of timber, and to acquire the form and functionality desired by engineers without calling the environmental friendliness into question. Wood modification processes are at various stages of development, and the challenges faced in scaling up to industrial applications differ. The aim of this book is to put together the key elements of the changes of wood constituents and the related changes in wood properties of modified wood. Further, a selection of the principal technologies implemented in wood modification are presented. This work is intended for researchers, professionals of timber construction, as well as students studying the science of materials, civil engineering and architecture. This work is not exhaustive, but intends to deliver an outline of the scientific disciplines necessary to apprehend the technologies of wood modification and its behavior during treatment, as well as during its use.
