Metallized Plastics interfacial interactions

The volume is divided into three parts Part I. Metallization Techniques and Properties of Metal Deposits, Part II, Investigation of Interfacial Interactions," and Part III, "Plastic Surface Modification and Adhesion Aspects of Metallized Plastics. The topics covered include various metallization techniques for a variety of plastic substrates various properties of metal deposits metal diffusion during metallization of high-temperature polymers investigation of metal/polymer inlerfacial interactions using a variety of techniques, viz., ESCA, SIMS, HREELS, UV photoemission theoretical studies of metal/polymer interfaces computer simulation of dielectric relaxation at metal/insulalor interfaces surface modification of plastics by a host of techniques including wet chemical, plasma, ion bombardment and its influence on adhesion adhesion aspects of metallized plastics including the use of blister test to study dynamic fracture mechanism of thin metallized plastics. 

The effect of the HBPs and dendrimer PAMAMs on the strength characteristics of aluminum-, PEI-, and magnesium-bonded joints based on epoxy and PU adhesives is very significant. This result can be attributed to the chemical interactions between the peripheral end groups of the branched PAMAMs and the epoxies and PUs at the joint interface. Furthermore, the interactions of the branched PAMAMs with the metallic or organic substrates may be physical or chemical in nature. Finally, the amount of the branched PAMAMs at the interface may not exceed a certain threshold, since plasticization of the epoxy and high primer thickness may cause inferior interfacial strength. 

When considering a paint formulation one must know the specihc interaction between the paint components and substrates. These processes are governed by interfacial phenomena such as wetting, spreading, deposition and adhesion of the paint components to the substrate. The latter can be wood, plastic, metal, glass, etc. The interaction forces between the paint components and the substrate must be considered when formulating any paint. In addition, the method of application can vary from one substrate and another.
