Irradiation processes have several commercial applications, in the coating of metals, plastics, and glass, in printing, wood finishing, film and plastic cross-linking, and in the fields of adhesive and electrical insulations. The advantages of this technology are well known. Radiation treatment on fabric and garments can add value in coloration, antifelting, printing, and coating. In this chapt...

D. J. Gardner Department of Forest Management and Advanced Engineered Wood Composites Center, University of Maine, Orono, ME 04469, USA Abstract The combination of synthetic thermoplastic polymers and wood is normally problematic because wood surfaces are hydrophilic while typical thermoplastic polymers are hydrophobic. A possible solution is to use block copolymer coupling agents. In this work...

The rising demand for consistent, high quality, as well as high density wood species has raised interest in diff erent wood modifi cation techniques. One modifi cation method is wood densifi-cation, where solid bulk wood can be compressed, following softening, until its density reaches that of the cell wall (1.50 g/cm 3). It is well known that many of the properties of solid wood correlate with...

The wood cell wall is composed of cellulose, lignin, hemicelluloses, and extractives. Thus, the surface energy of the wood material must be some combination of the surface energies of these components. The influence of extractives on wood surface chemistry can be important in diverse industrial applications, such as coating, pulping, and wood-based composites. In this study, pine wood meal was ...

Abstract Photochromic wood was fabricated by coating microencapsulated photochromic material (MP)/polydimethylsiloxane composites onto using a simple drop-coating method. Urea-melamine–formaldehyde resin used to microencapsulate the (PM) via in situ polymerization. The concentration of MP affected property surface. total color change (? E *) reached 82.2 when composite is 8%. Adhesion tests con...

Ultra-thin flexible glass with high transparency is attractive for a broad range of display applications; however, substrates with low optical haze are not ideal for thin film solar cells, since most of the light will go through the semiconductor layer without scattering, and the length of light travelling path in the active layer is small. By simply depositing a layer of TEMPO (2,2,6,6-tetrame...
