Abstract

As a natural and the most abundant material, wood was used as a scaffold for the grafting of acrylonitrile (AN) and ethyl acrylate (EA) to develop a novel grafted wood. Thus, chemical modification of the wood was carried out by means of grafting. It is clear from the characterization techniques (FTIR, SEM, and XRD) that grafting of acrylonitrile (AN) and ethyl acrylate (EA) was successfully performed on the Pinus roxburghii wood. Monomer and initiator concentration, temperature, time, and pH parameters have been varied to obtain the maximum percent grafting yield. A significant influence was observed on the physicochemical properties, morphological structure, and bacterial resistant nature after the graft copolymerization of AN + EA on the raw wood. This approach of grafting of wood would lead to the construction of a new class of materials with better properties and will also promote innovative consumption of renewable wood.

Summary

Introduction

Nature offers a number of biological materials that could be utilized for the preparation of new materials with desirable properties beneficial for one or other applications. E diverse synthetic materials have been extensively used for environmental detoxification as adsorbents and photocatalysts [4,5,6,7] Their expensive and toxic nature hinders their utilization at large scale. Ethyl acrylate (EA) and acrylonitrile (AN) were chosen as potential monomers for grafting onto raw Pinus wood because of their unique functionalities and diverse properties. E cellulosic fibres were functionalized by graft copolymerization of acrylonitrile/ethyl acrylate and were investigated for moisture absorption nature and chemical resistance under different environments [41]. We demonstrated how the functionality of acrylonitrile (AN) and ethyl acrylate (EA) can be grafted onto the wood and the obtained functional wood material possesses the novel profiles. We demonstrated how the functionality of acrylonitrile (AN) and ethyl acrylate (EA) can be grafted onto the wood and the obtained functional wood material possesses the novel profiles. is chemically modified wood was used for the physiochemical studies, and its antibacterial properties were studied in detail
