The study of air-plasma treatment on corn starch/poly(ε-caprolactone) films

摘要: In spite of usefulness synthetic polymers in every aspects life, the environmental hazards limit their use. Starch based biodegradable is one solutions to it. Packaging has a major share use polymers. For packaging application, it necessary have good surface and barrier properties material. Plasma modification materials promising solution enhance properties. present paper, cornstarch/poly(e-caprolactone) (CSPCL) films were treated air-plasma for different durations time. The effect treatment on biodegradation was studied. extent etching evaluated from weight change (%) study. Changes chemical composition analyzed using ATR-FTIR XPS. contact angle free energy (SFE) study indicate that leads hydrophilization CSPCL films. changes topography plasma processed AFM SEM. roughness caused by increase facilitates improvement adhesive like printability peel strength. studied water vapor oxygen transmission rate. Effect untreated samples simulating natural conditions controlled environment indoor soil burial method with single bacterial system comprising commonly occurring bacterium, Bacillus subtilis MTCC 121. While indicative due macro as well micro elements, microbial will identify interaction between microorganisms modified thus showing degradation process. Biodegradation assessed measuring loss tensile growth flora optical light microscopy (OLM). B. its number along brought about sample It observed such modifications enhanced rate finding application field, providing green increasing utilization addressing concerns.
