LDHs are efficient and environmentally friendly PVC thermal stabilizers, potentially replacing traditional toxic stabilizers like lead salts. Their thermal stabilization mechanism, chemical composition of metal layers and interlayer guests, and dispersion state in PVC composites play crucial roles in enhancing PVC thermal stability.
Poly(vinyl chloride) (PVC), an important thermoplastic polymer widely-used in various fields, requires the use of thermal stabilizers to enhance its thermal stability during polymer processing and practical applications because of the poor thermal stability. Layered double hydroxides (LDHs), two-dimensional anionic layered and versatile filler, are widely considered to be one kind of high-efficient and environment-friendly PVC thermal stabilizers. Interestingly, it is expected to gradually replace the traditional toxic thermal stabilizers such as lead salts. The recent development of LDH thermal stabilizers in PVC resins is here reviewed from four relevant aspects: - the thermal stabilization mechanism provided by LDHs, - the chemical composition of metal layers and - of interlayer guests, and - the dispersion state of LDH in PVC composites. The review provides a current picture to help in the choice of manufacturing of high-performance LDH thermal stabilizers.
