dc.abstract.enIn this paper, a nanocrystalline cellulose (NCC) functionalized with 4,4′-diphenylmethane diisocyanate (MDI) was used as a modifier for urea-formaldehyde (UF) adhesive in particleboard production. The applied method of NCC functionalization with diisocyanate has not been previously studied in research on wood-based materials. Chemical structure of MDI-NCC evaluated with Fourier transform infrared spectroscopy (FTIR) demonstrated some significant changes indicating that the functionalization was effective. No change in crystallinity caused by the modification was noted based on the lateral order index and total crystallinity index. Hydrophilicity of NCC was reduced due to the functionalization with MDI. Based on the differential scanning calorimetry (DSC) results, it was found that the reactivity of the resin was improved by the addition of NCC, and moreover, the effect was even more noticeable when the MDI-NCC was introduced. Properties of manufactured particleboards such as density, water absorption and formaldehyde content were not affected by the resin reinforcement. In turn, the modification of NCC with MDI allowed to increase the strength and reduce swelling of the particleboards more significantly than in the case of a neat NCC. It indicates that application of diisocyanate-functionalized NCC has great potential for the use as the UF resin modifier in particleboard production.
