    Beech (Fagus orientalis) wood modification through the incorporation of polystyrene-ricinoleic acid copolymer with Ag nanoparticles
    (Springer, 2022) Can, Ahmet; Sivrikaya, Hüseyin; Hazer, Baki; Palanti, Sabrina
    Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.

    Chemical Modification of Poplar Wood with Benzophenone Tetracarboxylic Di Methacrylates
    (2020) Can, Ahmet; Hazer, Baki; Sivrikaya, Hüseyin
    Aim of study: The aim of this study was to analyze the use of benzophenone tetracarboxylic di methacrylates material in wood modification process and the changes in poplar wood. Material and methods: Poplar wood (Populus euramericana) was impregnated with the hydroxyethyl (or glycidyl) methacrylate esters of 3,3,4,4-benzophenone tetracarboxylic dianhydride. The liquid esters were obtained by reaction of BTDA with hydroxy ethyl (BTD-H) (or glycidyl, BTD-G) methacrylate. The wood-BTD-H (and BTD-G) interaction was confirmed by the characteristic signals in Fourier-transform infrared (FT-IR) spectroscopy. The decay resistance and physical behaviour of the modified wood was investigated. Main results: The BDTA-H samples displayed less colour change than the BDTA-G samples. Before decay testing, mini-block samples were leached according to the European Committee for Standardization (EN 84 1997) standard, then control and modified samples were subjected to white-rot fungus (Trametes versicolor). Modification with BTD-G yielded a high improvement in decay resistance (68-72%). Highlights: In the esterification of the chemical, it is benefited only from the sun's rays without the need for high temperature and pressure.

    Thermal behavior and decay performance of wood modified with poly(ethyl cyanoacrylate)
    (Taylor & Francis, 2021) Can, Ahmet; Sivrikaya, Hüseyin; Hazer, Baki
    Ethyl cyanoacrylate polymerizes at room temperature, and is often used as an adhesive in many areas for a wide variety of applications. In this study, the possibility of using poly(ethyl cyanoacrylate) in the field of wood modification was investigated. For this purpose, Scots pine (Pinus sylvestris L.) and Oriental beech (Fagus orientalis) samples were impregnated with poly(ethyl cyanoacrylate) that was synthesized using acetone. Modified samples were characterized by Thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and Scanning Electron Microscopy (ESEM). Decay performance was done with white rot fungus (Trametes versicolor (L: Fr.) Pilat. (FFPRI 1030)) for beech wood and brown rot fungus Coniophera puteana for pine wood; the European standard EN113 FTIR analysis indicated that PECA could appreciably alter the chemical structure in modified wood. Thermal changes in modified wood were be minor compared to those of untreated wood. Samples treated with PECA had significantly lower mass losses than untreated samples as a result of fungal exposure to Coniophora puteana and T. versicolor.
