Research On The Effect Of LDHs On Improving The Performance Of LDPE Film

The nanoparicles with demension within l~100nm are hypo-steady mediacy between macro solid and molecule. Baded on four basic effects, as the surface effect, the volume effect, the quantum effect and the macroscopic quantum tunneling effect, the nanoparticles emerge some marvelous features and find a wide application prospect in the areas of material electronics, optics, biology, space-science, antibacteriuiTK dye, medicine and catalyze.Anionic two dimensions nanomaterial with samdwich is a kind of materials of Layered Double Hydroxide series. Its shortened form is LDHs. The especial chemical composing of LDHs endues itself with remarkable absorption effect for infrared. Its absorption range for infrared can be devised and adjusted to satisfy certain requirement because some organic molecules having absorption for infrared can be intercalated into place between two layers. If it is used in the film for agriculture, the heat preservation effect would be improved observably. In this paper, the following studies have been done during our research work.1. Some studies have been done on the dispersion of nanoparticles in the polymer and several factors influencing the dispersion effect are discussed. A appropriate way has been found to achieve even dispersion of nanoparticles in polymer.2. Such factors that affect the mechanical performance and optical performance have been investigated on the base of even dispersion. Some directions for proportion are obtained in company with the relation between microstructure and macroperformance of the compound.
