Nanoengineered bioplastics coatings for low friction applications
Innovative bioplastic coatings reinforced with nano-lignin for enhanced tribological performance, offering a biodegradable alternative for industrial applications like razor blade design. This green technology aims to replace environmentally harmful PTFE-based coatings.
Overview
The proposed solution is a nanoengineered bioplastic coating reinforced with nano-lignin, designed to offer superior tribological performance. This innovative coating is biodegradable and can be applied through a simple solvent casting process, making it an environmentally friendly alternative to traditional PTFE-based coatings. The technology is particularly transformative for industries such as razor blade manufacturing, providing a green, sustainable solution that reduces environmental impact.
Technical specifications
The bioplastic coatings are developed by integrating nano-lignin with biopolymers, inspired by natural processes. Key features include:
- Biodegradability: Derived from natural sources, these coatings can decompose without leaving harmful residues.
- Easy application: The coatings are applied using a solvent casting process, which is efficient and cost-effective.
- Enhanced performance: Reinforced with triboactive nanoadditives, the coatings offer improved microstructure, mechanical, and tribological properties.
The development process involves proprietary compositions and a structured three-phase validation to optimize performance and application.
Technology readiness level
Currently at TRL 4, this technology has been validated at a laboratory stage with plans for further development and pilot manufacturing. The ongoing research involves active collaboration with industry partners, ensuring that the final solution meets commercial requirements and environmental standards.
