Hansen solubility parameter approach for biodegradable polymer formulations
Utilize Hansen solubility parameters (HSPs) to identify bio-based plasticizers for biodegradable polymers, optimizing processability and compatibility. This innovative approach minimizes trial-and-error, enhancing formulations for eco-friendly applications.
Overview
This solution leverages Hansen solubility parameters (HSPs) to innovate in the field of biodegradable polymer formulations. By predicting the compatibility of various components using HSPs, this approach identifies bio-based, low-density plasticizers that enhance the processability of biodegradable polymers. This method offers a quantitative, efficient alternative to traditional trial-and-error formulations, making it especially valuable for developing eco-friendly materials to replace conventional polyolefins.
Technical specifications
Hansen solubility parameters (HSPs) break down the cohesive energy density of materials into three components: dispersion forces, polarity, and hydrogen bonding. These parameters are represented as points in a 3D space, where proximity indicates potential compatibility. By utilizing an extensive database of HSPs, this solution can efficiently pre-screen and identify suitable plasticizers and fillers for polymers like PLA, PBAT, PHA, and TPS. The formulation process includes compounding and testing using facilities at NC State University, ensuring the selected materials meet desired characteristics such as processability and food safety.
Technology readiness level
This approach has reached Technology Readiness Level 4, where it has been validated in a laboratory environment. Future validation will involve sponsored research, aiming to refine biodegradable polymer formulations using HSPs with support from industry partners to further advance towards commercial applications.
