Abstract

Purpose

The purpose of this study is to conduct an investigation into the potential characteristics of Pistia stratiotes at different maturity stages. The focus of interest was to specifically look at oleophilicity properties based on contact angle (CA) measurement.

Design/methodology/approach

The morphological characteristics were also examined using a variable pressure scanning electron microscope. Three different oils, namely, Bio Oil 1, Bio Oil 2 and MP-R 10W/40 semi-synthetic oil, were tested on the Pistia leaf surface to measure the CA and wetting properties.

Findings

It was found that both types of bio oils had distinct CA values compared to that of the synthetic oil. A maximum difference of 65° to 75° was recorded in CA values.

Originality/value

Based on the results, the maturity of leaves was found to affect the CA values.
