Abstract

Printed newspaper is one of the print-based media published daily in large quantities. The focus of this research is to remove the ink from used newsprint with alkaline treatment by using ultrasound sonochemistry method. Newsprint sheets collected were characterized by mechanical and morphology tests using FT-IR, XRD, tensile test and SEM. FT-IR spectra analysis shows the absorption of C=C functional groups as the main components of newspapers at 1427 and 1635 cm-1 wavelengths. The treatment with alkaline solution increased the mechanical strength properties of paper. SEM morphology analysis result shows that the surface of paper becomes more rough after ultrasound-alkaline treatment compared to paper without ultrasound treatment (conventional treatment). The crystallinity value decreased with alkaline treatment. The longer the ultrasound duration was, the lower the crystallinity degree became.

Abstract

Research on the use of modified bentonite from Bener Meriah Aceh to study the morphology and thermal properties of polypropylene-montmorillonite nanocomposite (PP-MMT) was carried out. Bentonite was isolated into nano-sized montmorillonite and modified with the addition of PP-g-MA as a compatibilizer and octadecylamine as a modifier of MMT. PP-MMT nanocomposite processing was carried out in an internal mixer at 180 oC with a time of 10 minutes, and a speed of 65 rpm. Based on the results of the TGA-DTA test, the modified bentonite from Bener Meriah Aceh with PP-g-MA and octadecylamine can improve the thermal properties of PP-MMT nanocomposite in a composition comparison of  PP; PP-g-MA; MMT is 85; 10; 5. The SEM test results also showed that exfoliation and intercalation had occurred of MMT at PP-MMT nanocomposite.
