Resumen
THE MAIN OBJECTIVE OF THIS STUDY WAS TO DEVELOP CELLULOSE NANOFIBERS FROM THE THERMOME-
CHANICAL PULP (TMP) OF RADIATA PINE (PINUS RADIATA D. DON), AND FOR THIS, A ONE-STEP MICRO-GRINDING
PROCESS WAS USED. THE NEWLY DEVELOPED MATERIAL WAS CALLED THERMOMECHANICAL PULP NANOFIBERS (TMP-NF). IN THE FIRST INSTANCE, A DETERMINATION OF THE CONSTITUENTS OF THE TMP WAS CARRIED OUT THROUGH A CHEMICAL CHARACTERIZATION. THEN, TMP-NFS WERE COMPARED WITH CELLULOSE NANOFIBERS (CNF) BY MORPHOLOGICAL ANALYSIS (SCANNING ELECTRON MICROSCOPY, SEM, AND ATOMIC FORCE MICROSCOPY, AFM), X-RAY DIFFRACTION (XRD) AND FOURIER-TRANSFORM INFRARED SPECTROSCOPY WITH ATTENUATED TOTAL REFLECTION (FTIR-ATR). IN ADDITION, FILMS WERE DEVELOPED FROM TMP-NF AND CNF USING A VACUUM FILTRATION MANUFACTURING METHOD. FOR THIS STUDY, 0.10, 0.25, 0.50, AND 1.00% DRY WEIGHT OF CNF AND TMP-
NF WERE USED AS CONTINUOUS MATRICES WITHOUT ORGANIC SOLVENTS........
