Photodegradation Protection of Polymeric Materials by Encapsulating with Inorganic Composites and Applications Thereof

Tech ID: 20B189

­Advantages:

  • Boosts the average lifespan of polymers preventing them from undergoing UV-induced photodegradation.
  • Decreases the frequency of replacements and repair process, which translates into tremendous cost savings.

Summary:

Various fields employ polymeric and organic materials which are prone to photodegradation under UV radiation and other forms of high-energy light. This degradation results in reduced lifetime and performance of the material, requiring regular replacements, thereby raising costs. Presently, existing solutions cannot adequately safeguard such materials for a long time.

This technology offers an innovative solution through structured core-shell particle design for encapsulating the protected material. Among others, the core may comprise thermochromic or phase-change materials while the shell is made up of metal oxides and other dopants capable of blocking harmful UV radiation. This technique also makes ensure the material retains its inherent properties making it different from counterparts that fail to offer long-term protection or versatility in many instances.

Process of forming a core-shell particle for protecting polymeric/organic materials. It details the steps from TCM core particle preparation, surfactant addition, micelle formation, and the encapsulation with titania-silica shell to block UV radiation and prevent photodegradation.
