Comparison of Chemically Treated Luffa cylindrica Using Fourier Transform Infrared Spectroscopy (FTIR) and Thermal Analysis

The world as we probably are aware of is confronting a major problem known as environmental pollution, therefore, leading to global warming. Researchers from around the world have been focusing on green composites to improve the general effect of polymer pollution leading to environmental pollution. This need has constrained numerous researchers to concentrate on making composites utilizing natural fibers and biodegradable polymers. Moreover, natural fibers are cheaper to purchase, have great mechanical properties, biodegradability and demand lower amount of production energy. This paper focuses on one of the natural fibers known as Luffa Cylindrica (LC). Chemical surface treatments are necessary in order to get the best adhesion possible between the polymer and fiber which leads to better mechanical properties. Therefore, in this paper sodium hydroxide, silane and acetylation chemical surface treatments were performed. Furthermore, with the help of Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and Derivative Thermogravimetry (DTG) it was predicted that all the chemical surface treatments were successful. With the help of the results it was predicted that these specific chemical surface treatments showed removal of hemicellulose and lignin. Furthermore, with the help of thermal analysis it was predicted that silane treated samples showed highest amount of thermal resistance whereas, acetylated samples predicted lowest.
