Biodegradable bio-based nanocomposites are the next generation of materials for the future. Renewable resource-based biodegradable polymers including cellulosic plastic (plastic made from wood), corn-derived plastics, and polyhydroxyalkanoates (plastics made from bacterial sources) are some of the potential biopolymers which, in combination with nanoclay reinforcement, can produce nanocomposites for a variety of applications. Nanocomposites of this category are expected to possess improved strength and stiffness with little sacrifice of toughness, reduced gas/water vapor permeability, a lower coefficient of thermal expansion, and an increased heat deflection temperature, opening an opportunity for the use of new, high performance, lightweight green nanocomposite materials to replace conventional petroleum-based composites. The present review addresses this green material, including its technical difficulties and their solutions.</p>10acellulose10alayered silicates and properties10aNanocomposite10apoly(caprolactone)s10apoly(hydroxy alkanoate)s10apolyiactic acid10aStarch1 aPandey, J., K.1 aKumar, A., P.1 aMisra, M.1 aMohanty, A., K.1 aDrzal, L., T.1 aSingh, R., P.  uhttps://library.ncl.res.in/content/recent-advances-biodegradable-nanocomposites-001984nas a2200253   4500008004100000022001400041245006900055210006800124260009900192300001400291490000700305520111100312653000901423653001801432653002401450653001801474100002901492700002201521700002301543700002001566700001801586700002401604856010201628       2006                        eng d  a0141-391000aPhotooxidation of vulcanized EPDM/montmorillonite nanocomposites0 aPhotooxidation of vulcanized EPDMmontmorillonite nanocomposites  aTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLANDbELSEVIER SCI LTDcDEC  a3033-30390 v913 a<p>The photooxidation of a vulcanized ethylene-propylene-diene monomer (EPDM)/montmorillonite nanocomposite as well as EPDM/nanocomposite with stabilizers was studied under accelerated UV-light irradiation (lambda &gt;= 300 nm, 60 degrees C) for different times. The development of functional groups during oxidation was monitored by infrared spectroscopy. Photodegradation of the neat polymer and composites took place and the increases of absorbance in hydroxyl and carbonyl groups with irradiation times and also the decreases of the EPDM unsaturations were measured. The data indicated that the photooxidation products were not changed in the presence of the nanofiller. However, the presence of MMt was observed to dramatically enhance the rate of photooxidation of EPDM with a shortening of the oxidation induction time, leading to a decrease of the durability of the nanocomposites. On the other hand, it was observed that addition of stabilizers, either Tinuvin P or 2-mercaptobenzimidazole, was efficient in inhibiting the degradative effect of MMt. (c) 2006 Elsevier Ltd.
