Polyethylene is one of the most important plastics produced today because of its good physical properties, ease of fabrication and low cost. Studies to improve the properties of polyethylene are leading to an understanding of its crystalline morphology. Polyethylene crystallized by evaporation from dilute solutions consists of thin crystals called lamellae. The polyethylene molecules are parallel to the thickness of the lamellae and are folded since the thickness of the lamellae is much less than the molecular length. This lamellar texture persists in less perfect form in polyethylene crystallized from the melt.Morphological studies of melt crystallized polyethylene have been limited due to the difficulty of isolating the microstructure from the bulk specimen without destroying or deforming it.

An environment-friendly surface etching and activation technics for ABS surface metallization were investigated as a replacement for conventional chromic acid etching bath and palladium catalyst. After etching by H2SO4-MnO2 colloid, the ABS surfaces became roughness; meanwhile the carboxyl and hydroxyl groups were formed on the surface. With absorption and a reduction by a dimethylamineborane solution, nickel particles were deposited on the ABS surface, which serves as a catalyst replacement for SnCl2/PdCl2 colloid. The effects of NiSO4 concentration, (CH3) 2NHBH3 concentration, reduction temperature and reduction time on the adhesion strength between the ABS surface and the electroless copper film were investigated.
