Humans cannot survive without water. Although the exact percentage varies depending on age and body composition, about 50–70% of the human body is made of water. Most of the water on Earth is seawater, and only about 2.5% is freshwater. Among that, the amount of freshwater available directly in rivers and lakes is only about 0.01%. It is clear that water is an extremely important and limited resource. 

​

People obtain domestic and industrial water mainly from rivers and lakes. Even when these water sources become polluted, natural purification processes—such as dilution, sedimentation, and microbial decomposition—help restore water quality. However, natural purification has limits. When the amount or type of pollution exceeds nature’s capacity, water quality deteriorates rapidly. Therefore, safely purifying water and keeping it usable in a sustainable way is a major challenge in modern society. 

​

Pellicola is a highly efficient water purification adsorbent capable of removing a wide range of contaminants in water. It can capture chemical substances that conventional materials struggle to remove, and it functions as a new water treatment technology that supplements natural purification processes. 

​

The high performance of Pellicola can be summarized in three key points: 

1. Extremely large surface area Its fine microstructure provides a vast surface for contaminants to adhere to, enabling high adsorption capacity. 

2. Chemical properties that selectively attract pollutants It efficiently adsorbs substances that are difficult to remove with conventional materials, such as PFAS, heavy metals, and organic pollutants. 

3. A structure that remains stable in water It does not easily degrade and can be reused many times, maintaining high purification performance while reducing treatment costs.
