In Materials Research, The Development Of Polymer Nanocomposites Is Rapidly Emerging As A Multidisciplinary Research Activity Whose Results Could Broaden The Applications Of Polymers To The Great Benefit Of Many Different Industries. Polymer Nanocomposites (PNC) Are Polymers (Thermoplastics, Thermosets Or Elastomers) That Have Been Reinforced With Small Quantities (Less Than 10 Wt. %) Of Nanosized Particles Having High Aspect Ratios. Elastomers And Commodity Thermoplastics Have A Big Potential For Applications In The Industry As Well As In Construction, Electrical Applications And Food Packagings. One Of The Few Disadvantages Associated With The Use Of Nanofillers Is Their High Cost. However, This Negative Effect Of The High Cost Is Counterbalanced As Only Relatively Small Amounts (2-5 Wt %) Of Nanofillers Are Needed. The Unique Properties Of These Materials, There Are Quite Enough Aspects, Associated With Their Structure And Mechanism Of Reinforcements. In Mechanical Reinforcement Major Issues Are The Homogeneous Dispersion Of Nanofillers In The Polymeric Matrix And The Developments Of Chemical Bonding Or Strong Interaction At The Nanofiller-Matrix Interface. Here We Have Used The Zn-Ion Coated Nanosilica Filler For Better Homogeneous Dispersion As Well As Enhanced Thermal Stability Of Commodity Thermoplastic Polypropylene (PP). The Effect Of Surface Modification Of Zn-Ion Coated Nanosilica With Diglycidyl Ether Of Bisphenol A (DGEBA) Has Also Been Studied For The Overall Property Improvement. Also The Work Has Been Extended Towards The Use Of Compatibilizers (PP-G- MA) As Well As Reinforcing
