Potential Replacement of Pentaeritritol Tetranitrate Explosive Aggregate Polymer (Petn): A Short Review

explosive Abstract The use of natural polymers as substitutes for synthetic polymers in the development of aggregating materials for the pentaerythritol tetranitrate (PETN), explosive is a poorly explored area, but with the ability to enable the development of new sustainable, more chemical friendly and economically, using as an alternative a renewable material like chitosan and its derivatives. Chitin, a natural polymer that makes up the exoskeleton of crustaceans, insects, and the fungal cell wall, along with their derivatives, such as chitosan, offer attractive chemical, physical, and biological properties. It is noteworthy that chitin is found in high abundance in nature, and allows obtaining materials capable of offering interesting characteristics, such as chelating capacity, biocompatibility, biodegradability, nontoxic [3]. In this review, is possible to see the possibility to use a natural polymers as a potential materials to use as na aggregate polymer in PETN, as well as the increasing trend of the use of renewable natural polymers to develop creation of materials with high technological grade for mant areas of application. The aim of this study is to show the potential of using chitosan as an aggregator polymer for PETN crystals.
