This paper discusses the syntax and semantics of -men and four types of phrases containing -men in Mandarin. I defend the view that -men should be analyzed as a plural morpheme as first argued in Li (1999) but argue against the analysis of positing -men in the D position or treating it as a definite determiner. It will be shown that definiteness is not inherent to -men and that -men is compatible with numerals and classifiers and should be in a position local to nouns. I propose an analysis of -men as an associative plural and explain the properties of the four types of expressions containing -men within a Neocarlsonian account of bare nominals. The formal account of the syntax and semantics of phrases containing -men advanced in this paper shows that it is not necessary to assume a functional category D that is always invisible in the grammar of Mandarin in order to account for the behaviors of its nominal arguments and argues for the lack of DP projections in Mandarin.

Flaky Cu (f-Cu) particles coated with various thickness of silica (SiO 2) were incorporated into poly(vinylidene fluoride) (PVDF) to investigate the effects of SiO 2 coating layer and its thickness on dielectric properties of the composites. The morphological and dielectric properties of the composites were characterized. The results indicate that the SiO 2 coating layer significantly affects the electrical properties of f-Cu@SiO 2 and f-Cu@SiO 2 /PVDF, and that the PVDF composites with f-Cu@SiO 2 particles exhibit superior dielectric properties compared with raw f-Cu. Dissipation factors (tanδ) of the f-Cu@SiO 2 /PVDF are remarkably suppressed and reduced to rather low level owing to the presence of SiO 2 shell which serves as an interlayer between the f-Cu particles preventing them from contacting with each other. Furthermore, the effect of suppression on tanδ tends to be more prominent as the thickness of SiO 2 coating layer increases. The as-prepared composites possess high dielectric constant and low tanδ, making them promising for the industrial application as embedded capacitors.
