Biomimetic laser-textured surfaces for advanced wetting and functional surface engineering
Expert research and consulting in biomimetic surface engineering using laser micromachining to create micro- and nanoscale textures that control wettability on metals, ceramics, and polymers. Services include drop impact analysis, flow studies, dynamic goniometry, and custom analytical setup design for evaluating barrier materials and functional coatings.
Overview
This offering centers on biomimetic surface engineering, drawing inspiration from natural surfaces such as lotus leaves and pitcher plants to create engineered textures with tailored wetting behavior. By applying novel laser processing techniques to metals, ceramics, and polymers, distinct micro- and nanoscale roughness structures are produced that confer specific functionalities, including self-cleaning, liquid repellency, and controlled fluid interaction. The work is especially relevant to industries evaluating barrier materials, container surfaces, and coatings where wetting dynamics, erosion resistance, and flow behavior are critical performance factors.
Technical specifications
Core capabilities:
- Laser micromachining of metals, ceramics, and polymers to generate micro- and nanoscale surface textures
- Wetting studies using drop impact analysis to evaluate erosion and damage during filling or impact events
- Flow studies measuring pressure drop and rheometry to assess turbulent flow suppression and the formation of air-trapping or liquid-infused barrier layers
- Conventional dynamic goniometry for contact angle and hysteresis characterization
- Design and fabrication of custom analytical equipment tailored to specific experimental needs
Applications:
- Testing and validation of novel barrier materials for packaging and container applications
- Evaluation of surface resistance to liquid erosion during high-speed filling processes
- Development of liquid-infused surfaces and air-layer barrier technologies
- Functional surface design for self-cleaning, anti-fouling, and fluid control purposes
Technology readiness level
The research program is backed by more than 13 years of specialized experience in laser-material interactions and surface wetting. Methods have been validated through extensive published research and applied across multiple material classes. The approach is ready for sponsored research collaborations, pilot studies, and contract testing engagements with industry partners seeking to evaluate or develop functional surfaces and barrier technologies.
