The Impact Of Natural Rubber As A Toughening Agent On The Strength, Degradability, And Toxicity Of An Algae-Based Bioplastic, Megan Driscoll

Honors College

With the growing attention on widespread plastic usage and its impact on the environment and human health, the need for sustainable alternatives to petroleum-based plastics is more important than ever. One of the most promising solutions is bioplastics; however, current bioplastics struggle to compete with the material properties of petroleum- based plastics. Agar is a sustainable algae-derived hydrocolloid polysaccharide that can be used for bioplastics and biofilms. Despite promising characteristics, bioplastics made from agar are brittle. Common additives, such as the plasticizer glycerol, offset brittleness but sacrifice strength in return. This study looks at the impact of natural rubber as …
