  • Method for forming composite materials
    Patent number: 9068056
    Abstract: Disclosed is layered double hydroxides (LDH) used to catalyze the polymerization of polyethylene terephthalate (PET). The LDH of a catalyst amount may efficiently reduce the PET polymerization period and further be uniformly blended into the PET product to form composites. Compared with the pure PET, the composite including LDH has better properties such as mechanical properties, linear expansion coefficient, barrier, thermal stability, and transparency. In addition, the LDH in the composite is safer than conventional heavy metal catalysts, especially when applied to food or drink packages.
    Type: Grant
