This document specifies requirements and recommendations for performance assessment methods for superhydrophobic surfaces and coatings subjected to mechanical stress, solar radiation and weathering, liquids, and thermal cycling, where applicable, based on the agreement between interested parties. The performance assessment is carried out based on comparative measurements of the advancing and receding angles and the calculation of the contact angle hysteresis before and after the above-mentioned working/environmental conditions. This document does not address safety and environmental related issues of such coatings. This document is applicable to any superhydrophobic surfaces and coatings (i.e. nanostructured) on which the measurement of the advancing and receding angles is possible.
Abstract
Overview
ISO/TS 10689:2023 - Nanotechnologies - Superhydrophobic surfaces and coatings: Characteristics and performance assessment - specifies methods to assess the performance of superhydrophobic surfaces and coatings (nanostructured) when exposed to mechanical stress, solar radiation and weathering, liquids, and thermal cycling. The standard defines a comparative, measurement-based approach: advancing and receding contact angles are measured and contact angle hysteresis is calculated before and after exposure to agreed test conditions. ISO/TS 10689:2023 applies where advancing/receding angle measurements are possible and does not cover safety or environmental aspects.
Key topics and requirements
- Performance assessment principle: comparative measurements of advancing angle, receding angle and calculation of contact angle hysteresis pre‑ and post‑exposure.
- Definition of superhydrophobicity: typically contact angle > 150° and contact angle hysteresis
