Synthesis And Characterization Of Lactic Acid Grafted Euphorbia Trigona Mill Latex Anti-Bacterial Adhesive

Abstract

The Increased Modernization Resulted In The Need For The Simplified Living Style Of Human Beings Which Includes The Use Of Smarter Materials In Day-To-Day Life. Those Materials Are Mainly Plastics Which May Have Adverse Effects On The Environment, And Thus Finding Greener Materials Is Needed. So, This Study Aimed To Synthesize Lactic Acid Grafted Euphorbia Trigona Mill Latex Anti-Bacterial Adhesive And Characterize The Synthesized Bio-Adhesive In Terms Of The Antibacterial Activity, Thermo gravimetric Analysis, And Adhesion Property. Euphorbia Trigona Mill Latex Was Modified With L-Lactic Acid (88%) With A Mix Ratio Of 1:3 (V: V) Of Lactic Acid To Etm Latex At A Reaction Temperature Of 150??C. The Lactic Acid Monomer Was Developed On The Backbone Of Etm Latex Through The Oh Active Site. This Was Confirmed By The Ft Ir And Nmr Analysis. The Thermal Stability Of The Synthesized Bio-Adhesive Was Investigated And Compared To The Starting Materials And Found To Be More Stable With A Maximum Degradation Temperature Of 370???. The In Vitro Antibacterial Test With Agar Disk Diffusion Assay Was Used To Investigate The Antibacterial Activity Of The Bio-Adhesive And It Was Found That The Bio-Adhesive Has Concentration-Dependent Activity Towards E.Coli And S.Aureus Bacteria. For 1wt%, 2wt% And 3wt% Of Bio-Adhesive An Increased Ant-Bacterial Activity Was Observed With A Zone Of Inhibition Of 9mm, 13mm, 15mm For E.Coli And 8mm, 11mm, 14mm For That Of S.Aureus Respectively. The Adhesion Nature Was Investigated By The Drag Method With An Experimental Procedure Developed In The Laboratory. The Commercial Adhesive Bandage Was Washed With A Solvent And Used As An Adhesive Bandage Fabric And 0.1gm Of Etm-L-Olla Was Applied On It And It Was Glued To A Leather Substrate. Then The Adhesive Performance Of The Etm-L-Olla Towards Peel Force Was Estimated Indirectly By Applying A Known Amount Of Mass. With This Experimental Procedure The Peeling Strength For The Synthesized Bio Adhesive Was Estimated To Be In Between Of The Maximum And Minimum Weight Recorded To Detach It From The Substrate And It Was Observed That The Adhesive Performance Increases With The Increase Of The Mix Ratio Of Etm Latex.
