A review of Polyvinyl alcohol / Carboxiy methyl cellulose (PVA/CMC) composites for various applications

Polyvinyl alcohol / Carboxiy methyl cellulose (PVA/CMC)  composite based on the synergic relation between two polymer, which attract considerable and develop a new blend with enhanced properties. Moreover, PVA is a kind of versatile polymer and contains high mechanical applications. On the other hand, although CMC possesses effective application due to its high biocompatibility and biodegradability, it shows weak mechanical properties. Therefore, this paper provides a review on the PVA/CMC composites for high potential of them on various properties (e.g. drug delivery, food packaging, agriculture, electric and physiochemical properties). Finally, it was found that these novel composites can alternative source for producing biomaterials and drug delivery systems as well as hydrogel networks are constructed from these hydrophilic polymers for hydrophilic drugs or holding water to deliver moisture to the wound site. Moreover these composite can provide controlled release fertilizer as effective application in agriculture. Thus, PVA/CMC composites based materials have a wide applicability and nice potential in the development of physiochemical and electrical properties.
