Development of 3D Printing Technique for Chicken Feather Powder Infused Biodegradable Polymer Films

Undergraduate #328
Discipline: Nanoscience
Subcategory: Materials Science
Session: 1
Room: Exhibit Hall A

Chicken feathers, which are a by-product of poultry industry are mostly disposed without any pretreatment causing environmental problems. They are made of high contents of a useful polymeric protein called keratin (91-93 percent). To make use of this protein, chicken feather powder (CFP) of an average diameter 40 µm was incorporated as a filler material for making films with biodegradable polymer ecoflex via simple solution blending technique followed by 3-D printing. The filler material was used in various weight fractions (1, 2, 6, 10, 15 and 20 wt. percent ). The influence of CFP as a reinforcement on mechanical and thermal properties was characterized via tensile and thermogravimetric analysis. From this study it can be concluded that CFP can be used as a useful filler for improving the mechanical and thermal properties of biodegradable polymer films (Ecoflex), with a better interface and proper dispersion properties can be further improved Thus, produced polymer films can further enhance barrier and antimicrobial properties which can be used for food packaging applications.

Role: I have collected the chicken feathers, cleaned them( for residue and outside elements). I also balled-milled the chicken feathers , and made the powder forty nanometers. Then, I mixed the solution with ecoflex, chloroform, and the chicken feather powder. I have printed the solution using a 3-D printer. Finally, I helped with the mechanical testing of the final product and compared the results to a blank and the variety of percentages). The rest of the testing SEM and thermogravimetric analysis was done by the student mentor.
