category: oxazolidine, Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout in the manufacturing process of chemical products. 497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2
Chemical modification of cellulose fibers with a trialkoxysilane has been performed and modified cellulose-castor oil polyurethane composites have been successfully studied. The modified cellulose and all composites was characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetry (TGA) and water uptake test (WU). Compared with the crude cellulose fibers, the organosilane treatment reduces the hydrophilicity of the natural fibers and increases the fiber/matrix compatibility. In addition, the better dispersion of treated cellulose fibers was characterized by scanning electron microscopy (SEM). Cellulose fiber modification effect on mechanical properties was investigated by uniaxial traction test. Results show an improvement of Young modulus and tensile strength. Composites thermal properties of are also improved after the organosilane treatment of fibers. These results are due to the interfacial adhesion improvement by the formation of chemical bonding between prepolymer isocyanate extremities and the glycidol grafted on cellulose surface.
