STUDY ON PROPERTIES OF COMPOSITE MATERIALS OF LAYERED DOUBLE HYDROXIDE AND POLYVINYL CHLORIDE

Layered Double Hydroxide (LDH) was synthesized and modified with different coupling agents, then modified LDH as heat stabilizer was filled into polyvinyl chloride (PVC) to form composite materials. Samples were characterized by XRD, IR, TEM and Particle Size Analysis. The results showed that dispersion properties of LDH in PVC were improved, and mechanical properties and heat stability of LDH/PVC composite materials were prompted.
