摘要:
A method of producing cellulose fibres impregnated with metal nanoparticles, particularly silver nanoparticles. The method comprises swelling cellulose fibres in an aqueous alkali solution (e.g. NaOH (aq)). The swollen cellulose fibres are removed from the aqueous alkali solution and mixed with an aqueous solution of a metal salt (e.g. AgNO3) and a polymer solution so as to impregnate the fibres with metal nanoparticles. The swollen cellulose fibres impregnated with metal nanoparticles are then removed from the solution. The invention further relates to the composition of cellulose fibres impregnated with metal nanoparticles and an absorbent material (e.g. wound dressing) comprising a blend of cellulose fibres impregnated with metal nanoparticles with at least one other type of fibre.
