摘要：

Nanometre-sized poly(vinylidene fluoride) (PVDF) particle domains in a confined space were obtained by blending PVDF with excess poly(methyl methacrylate) (PMMA). When these particles were small enough they showed beta -form structure, which was different from the structure of bigger particles or PVDF bulk. However, the beta -form was thermodynamically metastable because it could eventually be transformed to a more stable phase by annealing at a certain temperature. Larger particle domains were of identical phase to the bulk, indicating that small size favours the formation of the beta -form. (C) 2000 Society of Chemical Industry.
