“…The thickness of polymer thin film is a key factor determining its crystalline morphology [37]. On the basis of experimental observations in thin and ultrathin polymer films, the size effects related to film thickness have been widely investigated in the literature [37,[48][49][50][51][52][53][54][55][56][57][58]. When the film thickness is much larger than 100 nm, regular spherulites similar to those observed in bulk crystallization are generally formed.…”

Due to the effects of microphase separation and physical dimensions, confinement widely exists in the multi-component polymer systems (e.g., polymer blends, copolymers) and the polymers having nanoscale dimensions, such as thin films and nanofibers. Semicrystalline polymers usually show different crystallization kinetics, crystalline structure and morphology from the bulk when they are confined in the nanoscale environments; this may dramatically influence the physical performances of the resulting materials. Therefore, investigations on the crystalline and spherulitic morphology of semicrystalline polymers in confined systems are essential from both scientific and technological viewpoints; significant progresses have been achieved in this field in recent years. In this article, we will review the recent research progresses on the crystalline and spherulitic morphology of polymers crystallized in the nanoscale confined environments. According to the types of confined systems, crystalline, spherulitic morphology and morphological evolution of semicrystalline polymers in the ultrathin films, miscible polymer blends and block copolymers will be summarized and reviewed.

“…The morphology of iPP crystallized from the melt has been studied extensively over the past few decades using PLM [45][46][47], transmission electron microscopy (TEM), scanning electron microscopy (SEM) and atomic force microscopy (AFM) [48]. From investigation carried out by polarizing microscopy, dynamically and isothermally, on the analysis of nucleation morphology of iPP, a lot of information concerning the induction period, nucleation density, growth-rate of the spherulites, and distribution of the dimension of the spherulites can be obtained (Fig.…”

“…Isotactic PP has been studied extensively for its polymorphic characteristics and crystallization behavior since 1960s [9] and the results of these studies are reported in many monographic [see, for instance summarized Ref. 10 and 11] and journal publications [12][13][14][15][16][17][18][19]. Its crystalline morphology influences greatly the overall polymer properties (rheological, physical and mechanical) and the properties of the final products made of PP.…”

Polypropylene is an extremely versatile thermoplastic polymer known for its good performance/price ratio, excellent heat, moisture and chemical resistance, favorable processing characteristics and recyclability. Due to its universal properties, polypropylene is applied in numerous industrial fields such as electronic and electrical, automobile, textile, pipeline, etc. Furthermore, the progress in its synthesis and property modification in the last decade has contributed to the development of new polypropylene based materials with advanced performance. This review aims at reporting on some recent developments in polypropylene based materials, such as nanofibers, natural fiber reinforced composites, self-reinforced polypropylene and polypropylene/clay hybrids, that have replaced many types of engineering thermoplastics in high-performance applications.
