Preparation of novel hydrophobic cellulosic composites containing Silver (I) acylpyrazolonato
The surface modification of cellulose is central for a fast growing area of applications, since most vegetable-derived natural polymers are renewable materials, some of them displaying properties comparable to those of petroleum derived products.(1) The preparation of highly hydrophobic cellulose based materials is particularly important in the field of food packaging. Most materials used for food packaging applications are still produced from fossil fuels, so non-renewable and also nearly non-biodegradable, therefore representing an environmental problem.(2) In order to prepare hydrophobic cellulose, the hydroxyl groups are chemically modified, due to their reactive nature compared to the rest of the molecule. To date, fluorochemicals are usually employed for this purpose.
