The project studies wood surface properties. The main objective is physical and chemical modifications of wood surface and of film-forming materials (coating and gluing substances), with the aim to control wood interactions with these materials in liquid and solid phase. There are also investigated multiple factors influencing wood surface properties (wood species, moisture content, mechanical treatment mode; surface pre-treatment with plasma, nano-particles, natural polymers, heat, and similar), and the way how these factors affect wood interactions with film-forming materials. The project covers:
- morphology, chemical structure and discolouration in different modified wood surfaces,
- wood wetting with standard liquids, coating and gluing substances; specifying wood thermo-dynamic characteristics,
- phenomena at the interface wood – film-forming material in liquid and solid phase,
- stress patterns developed at the interface wood – film-forming material and in glue lines developed under different loading modes
- testing new materials (fillers, additives, colloids) with unique adsorption and physical-mechanical performance with the aim to obtain modified surfaces and gluing mixtures with specified properties,
- wood discolouration, wood degradation and the colour stability of treated surface in ageing process
For all these research areas, there have been specified partial goals and the methodology appropriate. This comprehensive approach should give optimum parameters guaranteeing appropriate wood surface quality. The results will serve as background for designing methods for purpose-oriented wood surface modification aimed to improve the quality and stability of surface treatment and of glued joints, and to decelerate the ageing process of the original wood substrate and of the treated wood surface.
The project focuses on a study of physical-chemical modification of wood surface and film-forming substances (coating materials and glues), with the aim to adjust the wood interactions with these materials in liquid and solid phase according to the related purpose. The project concerns the following research areas:
- wood structure, wood surface properties and interactions at the interface between wood and film-forming materials in liquid and solid state,
- testing of novel materials with specific physical-mechanical properties with the aim to improve wood surface properties and properties of film-forming materials, with primary concern on surface treatment,
- experimental study and modelling of stress states developed across the wood film-forming material interface during various loading modes and colour stability of surface-treated wood in ageing process.
This comprehensive approach to the issue solved can assure improved quality and stability of the surface treated or joint glued
