“…They increased from 110 Å for RM-1000 up to 130 Å for RM-2000. The lengths of rigid blocks, found according to the methodics of [19], changed from ~ 55 up to 70 Å. SAXS background is caused by an irregular fraction of SPU structure, which includes both layer-like structures, where alternating regularity of rigid and flexible segments is disturbed by more than 20 % (for more detail see [13]), and domains of larger and smaller size than in regular fraction, as well as density fluctuations up to micropores.

“…), before and after the incubation of their films of 150-200 µm thickness in blood serum at 313 K during 6, 12 and more months. Sample preparation, the analysis of structural, and mechanical characteristics are the same as in [13][14][15][16]. Small-angle X-ray diffraction patterns (SAXS) were obtained by the device with linear coordinate detector.…”

Poly(vinyl alcohol) is one of the most attractive polymers with a wide range of uses because of its water solubility, biocompatibility, low toxicity, good mechanical properties, and relatively low cost. This review article focuses on recent advances in poly(vinyl alcohol) electrospinning and summarizes parameters of the process (voltage, distance, flow rate, and collector), solution (molecular weight and concentration), and ambient (humidity and temperature) in order to comprehend the influence on the structural, mechanical, and chemical properties of poly(vinyl alcohol)-based electrospun matrices. The importance of poly(vinyl alcohol) electrospinning in biomedical applications is emphasized by exploring a literature review on biomedical applications including wound dressings, drug delivery, tissue engineering, and biosensors. The study also highlights a new promising area of particles formation through the electrospraying of poly(vinyl alcohol). The limitations and advantages of working with different poly(vinyl alcohol) matrices are reviewed, and some recommendations for the future are made to advance this field of study.

“…Polyvinyl alcohol (PVOH) is used in a number of applications including as surgical threads [1], lacquers [2], resins [3], food packaging materials [4], films with high oxygenbarrier properties [5], paper coatings and liners [6], water soluble films [7], electronics [8], coatings [9], printing [10], cosmetics [11], warp sizing and processing of textile fibres [12], drug delivery [13], contact lenses [14], biomaterials [15] and cements [16]. Given that there is such a wide diversity of applications of PVOH, there is a broad range of surface property characteristics required of the material which is dependent on its specific use and the industrial process in which it is utilised.…”

Understanding the effect surface production has on polymer properties is important in the design of advanced materials. The aim of this study was to determine how the moulding process affected the rate of hydrolysis and the topography, chemistry and physicochemistry of PVAc moulded, hydrolysed surfaces. Three different mould surface materials were used to produce compression moulded PVAc sheets which were treated with aqueous NaOH at a range of concentrations. The Textile moulded sheet demonstrated the best hydrolysis results. The topography of the moulded sheets was transferred to the surfaces and the Kapton release sheet was visually smooth at lower magnification and demonstrated some pitting at higher magnification. The Teflon surface had features transferred from the coated stainless steel at lower magnifications and linear features at higher magnifications and the textile surface had a wrinkled appearance and irregularly spaced peaks. The release sheet used to mould the PVAc surfaces, affected the physicochemical parameters. The Kapton moulded surface demonstrated the most polar attributes and the Teflon surface the most dispersive. It was clear that the selection of the mould material had an influence on surface properties and hydrolysis of moulded PVAc. Such information is important for engineering design in industrial processes.
