Sažetak
This paper reports on research of possibilities for composite materials bio matrices synthesis from MDF boards withdrawn from usage. Bio matrices were cast produced using re-defibrated wood fibres as raw material for cellulose polymorphs isolation and acetylation. As acetylation reaction time and temperature directly influence cellulose acetate yield, apparent acetyl content and its degree of substitution, three different time spans and two different temperatures of acetylation process were examined. Transfer from cellulose to cellulose acetate was determined using FTIR spectroscopy and cellulose acetate yield was determined quantitatively. The degree of substitution was calculated based on results of apparent acetyl content determined according to ASTM D817-96 standard. Results of FTIR analysis confirmed cellulose transformation to cellulose acetate, and that cellulose acetate yield and degree of substitution change almost proportionally with extension of reaction time and temperature. Therefore results of this research should contribute to further understanding of the specific problems regarding bio matrices synthesis.
