Abstract
Composite materials derived from eco-friendly natural fibres and other biodegradable materials have gained prominence in industrial applications due to their sustainability and reduced greenhouse gas emissions attributes in comparison with conventional reinforcements such as glass and carbon fibres. Application of natural fibre-polymer composites (NFPCs) in different industrial applications provides competitive edge due to its lightweight, higher specific mechanical properties than glass fibres, sustainability and lesser cost involved in production. There are certain challenges associated with natural fibers and its reinforcement in composites such as poor bonding between the fibres and matrix due to its contradictory nature of characteristics, moisture absorption, lower thermal properties and poor interfacial adhesion between the natural fibre and polymer matrix. The challenges involved in NFPCs needs to be overcome to produce materials with relatively equivalent properties to that of conventional compositesand other metallic structures. Several researchers around the globe have conducted investigations with the primary attention being paid to the modification of natural fibers and matrix by employing surface treatments and other chemical treatment methods. In order to address the need for eco-friendly and sustainable materials in different domains, a comprehensive review on natural fibers and its sources, available matrix materials, modification techniques, mechanical and thermal properties of NFPCs is needed for better understanding of behavior of NFPCs.This work provides the information and wholistic view of natural fibre reinforced composites based on the results obtained from modification techniques,with the view of focusing the review in terms of different chemical and physical treatment techniques, modification of fibers and matrix and enhanced mechanical and thermal properties in the composites.

[PMID: 33004929 PMCID: PMC7529777 DOI: 10.1038/s41598-020-73337-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Accepted: 08/21/2020] [Indexed: 11/09/2022] Open
Abstract
Betel quid (BQ) is a chewing mixed package that mainly contains areca nut (AN), betel leaf (Leaf) or betel stem inflorescence (SI), and slaked lime, and is consumed with or without tobacco BQ chewing is common in South East Asia and has been strongly associated with malignant and potentially malignant diseases of the oral cavity. Alkaloids such as arecoline are often accounted for the carcinogenic potential of BQ, however the chemical composition of BQ has not been studied in detail. In the current study, we investigated the total phenolic content (TPC), antioxidant activity (by mean of ferric reducing antioxidant power, FRAP), radical scavenging activity (DPPH test), polyphenolic profile and arecoline content in different components of BQ, namely AN, Leaf or SI, Husk, and blended BQ (BQ mix, containing AN, Leaf or SI and slaked lime). Samples were imported from 4 major regions of Indonesia, namely: Banda Aceh (BA), North Sumatra (NS), West Kalimantan (WK) and West Papua (WP). The highest TPC, FRAP, and DPPH values were detected in AN samples compared to other BQ components, while samples from WP region were of higher values compared to the other regions. High performance liquid chromatography—Mass Spectrometry (LC–MS) analysis showed that Husk contains the widest range of polyphenols, including hydroxybenzoic acids, hydroxycinnamic acids, flavanols, flavonols and stilbenes. Catechin and epicatechin were the main polyphenols detected in BQ, and they were present at the highest concentrations in WP–AN sample. Arecoline was detected in all AN and BQ mix samples and was significantly correlated with catechin and epicatechin, and significantly negatively correlated with p-hydroxybenzoic acid. Notably, arecoline concentration changed significantly when AN was blended in BQ mixtures. The current study is the first to extensively characterise the chemical composition of BQ and provides insight for a better understanding of the interactions of BQ alkaloids and phenolics in the development of oral submucous fibrosis and oral cancer.
