Description of Requirement:
A mixed aqueous dispersion of polydopamine polyurethane phase change materials with photothermal properties has been developed by a university in Turkey. The surface of these polymer particles is coated with polydopamine. The material can be used in functional coatings, adhesives, films, elastomers, films and foams. The university is seeking industrial partnerships in the textile, medical, disinfection, coating industries under technical cooperation and licensing agreements.

1. Product details
Polydopamine is an interesting polymer found in nature whose chemical structure makes it impossible to easily mix or incorporate with other polymer matrices while maintaining its properties, such as photothermal activity.
There are other compositions and studies to obtain light energy conversion materials, including the use of various nanomaterials or polymer components in different compositions, but none of them have suggested a solution or extracted a composition with photothermal activity to The various forms of products proposed in the present invention are obtained.
Photothermal materials can efficiently convert light into heat by non-emissive deactivation of the collected light, resulting in a significant local temperature increase. The heat generated by photoactivation of photothermal materials can trigger a variety of easily controllable thermal processes.
The invention presented by the University of Turkey presents a novel and feasible method to incorporate polydopamine into different polymer matrices via in situ polymerization of dopamine in given polymer dispersions and emulsions.
Although the present invention is demonstrated with aqueous polyurethane dispersions, this approach can be extended to other types of polymer emulsions and dispersions of interest. In addition, the present invention also proposes a novel composition containing PDA-PU (polydiacetylene-polyurethane) particles mixed with a phase change material (phase change material), which enables the manufacture of thermal comfort and cushioning materials for various applications , which has not been reported in the prior art. The material can be used in a wide range of critical applications including:
- Destroy tumors by laser
- Light-activated disinfection of surfaces by killing microorganisms
- Solar powered water evaporation for desalination/purification
- Light-activated controlled release of molecules
- Design of light-activated shape memory/self-healing materials for applications in medical, textile, materials, coatings, and sterilization.
The university is seeking industrial partnerships with the textile, medical, disinfection, coating sectors to develop a hybrid water-dispersed phase change material with photothermal properties and is interested in custom applications. The role of the partner: to test the performance of materials in their products or processes, to develop new applications.
2. Advantages and Innovation
Mixed one-component dispersions or emulsions are obtained, which can be used to easily manufacture various articles such as coatings, films, membranes, elastomers, adhesives, foams, sponges with photothermal activity.
The present invention eliminates the use of secondary nanoparticles and catalysts, and provides an easy-to-use environment-friendly, water-based, one-component platform.
