Review Article
Phase change textiles (PCTs) have attracted significant attention in recent years due to their unique capacity to undergo reversible solid-to-liquid phase changes at a specific temperature. These textiles have the potential to enhance thermal comfort, energy efficiency, and environmental sustainability in a range of fields. In this review article, we summarize the properties of PCTs and discuss their applications in various sectors. We also present a critical evaluation of the current status and future prospects of PCTs in terms of their properties and applications.
Properties of Phase Change Textiles
Phase Change Behavior
PCTs undergo a reversible solid-to-liquid phase change at a specific temperature, typically between 20°C and 40°C. This phase change behavior allows them to store and release heat at a constant temperature, providing a comfortable thermal environment for users. The phase change temperature can be tailored to meet specific application requirements by adjusting the chemical composition of the textile.
Thermal Properties
PCTs exhibit excellent thermal properties, including high heat capacity and low thermal conductivity. These properties contribute to their ability to store and release heat efficiently, providing a stable thermal environment for users. The thermal properties of PCTs can be further enhanced by incorporating other materials or structures that improve their heat storage capacity or reduce their thermal conductivity.
Chemical Composition
PCTs are typically composed of polymers or inorganic salts that undergo phase changes at specific temperatures. These materials are selected based on their phase change temperature, thermal stability, and compatibility with other materials in the textile matrix. The chemical composition of PCTs can be tailored to meet specific application requirements by adjusting the type and proportion of phase change materials used.
Mechanical Properties
PCTs exhibit good mechanical properties, including high tensile strength and elongation at break. These properties contribute to their durability and performance in various applications. The mechanical properties of PCTs can be further enhanced by incorporating other materials or structures that improve their mechanical stability or reduce their susceptibility to damage.
Applications of Phase Change Textiles
Construction
In construction, PCTs can be used as thermal insulation materials to enhance energy efficiency and reduce heating and cooling costs. They can also be incorporated into building materials to provide a comfortable indoor environment by reducing temperature fluctuations.
Clothing
In clothing, PCTs can be used to enhance thermal comfort and regulate body temperature. They can be incorporated into various types of clothing, including jackets, pants, and hats, to provide a stable thermal environment for users. PCT-based clothing also has potential in sportswear and outdoor activities due to its ability to absorb sweat and release it at a controlled rate.
Healthcare
In healthcare, PCTs can be used in medical devices and equipment to enhance patient comfort and improve therapeutic outcomes. For example, they can be incorporated into surgical dressings to provide a stable thermal environment for wound healing. Additionally, PCT-based materials can be used in bandages and wraps to provide therapeutic heat therapy for various medical conditions.
Environmental Sustainability
PCTs also have significant potential in terms of environmental sustainability. Their ability to store and release heat efficiently can contribute to reduced energy consumption and lower greenhouse gas emissions. Additionally, many PCTs are made from renewable resources or are biodegradable, further reducing their environmental impact. Their use in construction, clothing, healthcare, and other fields can contribute to reduced energy use and environmental degradation. For example, using PCTs in place of traditional thermal insulation materials can reduce energy consumption and improve environmental performance. Additionally, incorporating PCTs into clothing can enhance thermal comfort while reducing the need for additional heating or cooling equipment. Finally, using PCTs in healthcare applications can enhance patient comfort and reduce the need for costly medical treatments while being environmentally friendly. Future Prospects of Phase Change Textiles Although PCTs have significant potential in various applications due to their unique capacity to undergo reversible solid-to-liquid phase changes at a specific temperature, there are several challenges that need to be addressed before their widespread adoption can be achieved. One major challenge is the cost-effectiveness of these textiles compared to traditional materials used for thermal management. Although PCTs offer unique properties that can enhance thermal comfort
