Synthesis and Mechanical properties for Urethane foams using Nanocellulose dispersed in isosorbide |
| 초록 |
Nanocellulose (NC) dispersed in Isosorbide was incorporated in polyurethane foams (PUFs), using Poly(tetrahydrofuran)(PTMG), Polycaprolactone diol (PCL), in a ratio of 1:1 and 4,4'-diphenylmethane diisocyanate (MDI) as a prepolymer part. PUFs were produced by using the qusai-prepolymer method in which excess isocyanate reacts with the residues. Mechanical and morphology properties measured by Thermogravimetric analysis (TGA), Differential Scanning Calorimetry (DSC), Universal Testing Machine (UTM) for split tear, Ball drop impact test machine, Scanning Electronic Microscopy (SEM) images, Shore Durometer C type. It was confirmed that the mechanical properties of the NC dispersed in isosorbide were better compared to those without NC. This result indicates that addition of the nanocellulose could be an effective way to improve the mechanical and thermal properties of PU foams. |
