Improvement of physical properties of jabon (Anthocephalus cadamba) through the impregnation of nano-SiO₂ and melamin formaldehyde furfuril alcohol copolymer

Abstract

Wood polymer nano composites (WPnC) based on nano-SiO2 were prepared by the impregnation of nano-SiO2 and melamine formaldehyde-furfuryl alcohol copolymer. The objectives of this research were to analyze the effect of impregnation of nano-SiO2 and Melamine Formaldehyde Furfuryl Alcohol (MFFA) copolymers on the physical properties of jabon wood and to characterize treated jabon wood. Impregnation method improved the physical properties of jabon wood. Density of jabon become 0.56 g/cm3, weight percent gain (WPG) is 68.34%, Anti-Swelling Efficiency (ASE) is 46.66%, bulking effect (BE) is 7.55%, water uptake (WU) is 75.49%. WPnC composites were characterized by Fourier Transform Infrared Spectroscopy (FTIR), XRD (X-ray Diffraction), SEM (Scanning Electron Microscopy), and SEM-EDX (Energy-dispersive X-ray Spectroscopy). FTIR results showed that the Si-O-Si asymmetric stretching vibration hand slighty shifts toward a higher wave number. It indicated a reaction between nano-SiO2 and wood. XRD studies indicated a decrease in crystallinity of the composites. SEM images observed distribution of nano SiO2 in the composites.

Fast-Growing Magnetic Wood Synthesis by an In-Situ Method

“…Our results contrasted with those from previous studies [ 21 , 40 , 41 , 42 ]. The ASE value of magnetic jabon wood with the strong base NaOH (64.3%) used in the in-situ method was lower than with the weak base NH 4 OH (87.0%).…”

Characteristics of Magnetic Sengon Wood Impregnated with Nano Fe3O4 and Furfuryl Alcohol

“…Adding Fe 3 O 4 and FA to sengon wood makes the treated wood denser and has higher dimensional stability. Prihatini et al (2020) showed that FA combined with melamine-formaldehyde increased the BE values.…”

“…Wood impregnation involves introducing chemicals into pores, lumens, and cell walls to precipitate and store chemicals without damaging the wood. Impregnation methods have been applied to fastgrowing wood to improve wood quality using chemicals such as methyl methacrylate (Cahyono et al, 2020;Hadi et al, 2019), phenol-formaldehyde (Sumardi et al, 2020), melamine formaldehyde, furfuryl alcohol (FA); (Prihatini et al, 2020), nano TiO 2 (Rahayu et al, 2022b) and magnetite (Fe 3 O 4 ) nanoparticles (Rahayu et al, 2022a).…”

Physical Properties of Fast-Growing Wood-Polymer Nano Composite Synthesized through TiO2 Nanoparticle Impregnation

“…In addition, the impregnation process involves chemical reaction between the impregnation compound and the most reactive groups in the wood cell wall [ 6 , 7 ]. Many studies have been conducted on impregnation of fast-growing wood to improve the quality, using chemicals such as methyl methacrylate [ 8 , 9 , 10 ], phenol formaldehyde [ 11 , 12 ], monoethylene glycol [ 13 ], melamine formaldehyde and furfuryl alcohol [ 14 ], and nano Fe 3 O 4 [ 15 ].…”
