Abstract
The existence of many forms of “liquid wood”, even in the same subgroup, is explained by the fact that the main matrix is made of lignin and lignin can be found in nature in over 60 presentation forms. The lignin molecule is a complex macro – molecule made of three molecules which link together in various shapes. At the same time, structurally speaking, the lignin molecule is dependent on the type of plant species from which it is sourced. It results that the type and the structure of the lignin molecule – and implicitly the “liquid wood” biocomposite matrix – has a major role in the forming and the structuring of every type of “liquid wood”. In the current article, a comparative study of the properties of “liquid wood” pertaining to all three subgroups is presented. The chosen types are: Arboform F45, Arbofill Fichte and Arboblend V2 (which is the subject of the entire study).
