At this time, covering technologies used in finishing furniture use mainly volatile organic compounds (VOCs), which mean that it is almost impossible for most furniture factories to join the regulations contained in European Directives. Reducing emissions of volatile organic compounds (VOCs) is a necessity for environmental protection and health. Alternative technologies for wood industry (furniture mostly) exist, but it is very hard the optimization of performance, film and issue costs. On the other hand, the use of inorganic particles in the nanoscale range is particularly attractive since it allows improving the properties of the copolymers by controlling the degree of interaction between the polymers and nanoparticles. Addition of nanoparticles as additives in coating systems, kept their general characteristics, the same chemical nature but improves certain properties such as hardness and scratch resistance. Therefore, the purpose of our research was to improve the properties of coating existing systems using waterborne polymers and inorganic nanoparticles. The paper presents the synthesis and characterization of hybrid coatings materials based on inorganic nanoparticles and acrylic copolymers. These coatings materials were deposited as films on different lignocellulosic composites, characterized in terms of physical-chemical and mechanical properties. The composition and surface structure of coated lignocellulosic composites were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), optical microscopy and Fourier transform infrared spectroscopy (FTIR), in order to see the dispersion of nanoparticles in the polymer and bonds configuration. The coatings systems for lignocellulosic composites were developed and tested for their performances, besides improving the properties of resistance and durability, ensure effective protection and support high aesthetic.figureLignocellulosic composites coated with hybrid materials based on copolymers and inorganic nanoparticles |
