Study of compatibility of alcohol blended chemicals for modification of natural fibres in synthesis of biocomposites by ultrasonic technique

Abstract

Natural fibres have so many advantages such as abundantly available, low weight, newlinebiodegradable, cheaper, renewable, low abrasive nature, interesting specific properties, as these are waste biomass and exhibit good mechanical properties.Natural fibres also have some disadvantages such as moisture absorption, quality variations, low thermal stability newlineand poor compatibility with the hydrophobic polymer matrix. The surface of the fibre is required to chemically modify in order to remove or minimize the lignin content. Chemicals may activate hydroxyl groups or introduce new moieties that can effectively newlineinterlock with the matrix. Generally, chemical coupling agents are molecules possessing two functions. The first function is to react with hydroxyl groups of cellulose and the second is to react with functional groups of the matrix. There are many methods for study of compatibility of the liquid mixture.
