“…Electrospinning is very adequate to generate roughness in the sub-micron range since both fibrils and fiber separation are in this order of magnitude. It should, thus be expected that water contact angle in electrospun mats depends on morphological parameters such as fiber orientation and porosity or fiber diameter [31][32][33]. The generation of topography in the nanometric scale on the submicron rough surface with an additional decoration of the electrospun fibrils or the space among them produces an increased tendency to water repulsion producing superhydrophobic surfaces.…”

Royal Society of ChemistryAreias, A.; Ribeiro, C.; Sencadas, V.; Garcia Giralt, N.; Diez Perez, A.; Gómez Ribelles, JL.; Lanceros Mendez, S. (2012). Influence of crystallinity and fiber orientation on hydrophobicity and biological response of poly(L-lactide) electrospun mats. Soft Matter. 8 (21) AbstractPoly(L-lactide) electrospun mates have been produced with random and aligned fiber orientation and degrees of crystallinity from 0 up to nearly 50%. These two factors, fiber alignment and degree of crystallinity strongly affect the hydrophobicity of the samples, being this larger for the aligned fiber mats and for the fibers with higher degree of crystallinity. Whereas the first effect can be associated to a decrease in the degree of porosity the second should be related to variations in the fiber roughness at nanometric scale and an increase in fiber stiffness. Proliferation of human chondrocytes cultured in monolayer on these substrates is similar in both aligned and non-aligned amorphous mats. Crystallization of the aligned mats, on the other hand, nearly suppresses proliferation and the cells produce higher amounts of aggrecan, characteristic of the extracellular matrix of hyaline cartilage.

“…Under common processing conditions, isotactic PP often shows an α crystalline form. Figure 3C shows that, in the XRD test, when 2θ was 14.1°, 16.8°, 18.5°, 21.3°, and 21.8°, the corresponding Bragg diffraction characteristic peaks of PP were accompanied by crystal plane diffraction of (110), (040), (130), (111), and (131) [1,[12][13][14]. The results illustrated that, for PP90/TPU10 and MPP/TPU, the diffraction peak remained the same, indicating that adding TPU did not create a new crystalline structure [15,16].…”

“…Polypropylene (PP) is a commonly used plastic material composed of semi-crystalline polymer and exhibits easy processing, chemical resistance, high rigidity, light weight, and a reasonable, relatively low cost [1,2]. However, PP has some disadvantages, such as a large shrinkage ratio, great brittleness at low temperature, and low impact resistance, and thus its development is limited.…”

The Effects of Thermoplastic Polyurethane on the Structure and Mechanical Properties of Modified Polypropylene Blends

Abstract:In this study, a melt-compounding process was used to produce ordinary polypropylene (PP)/thermoplastic polyurethane (TPU) blends and modified impact-resistant polypropylene (MPP)/TPU blends. The influences of TPU on the blending morphology, melting behavior, crystallization behavior, and mechanical properties of these blends were investigated. Differential scanning calorimetry results show that using TPU influences the crystalline and melting behavior of PP/TPU blends, but not of MPP/TPU blends. X-ray diffraction analysis indicated that the presence of TPU neither influences the crystalline structure of PP nor creates new crystalline peaks. The mechanical property test results revealed that PP/TPU blends demonstrate better tensile strength, Young's modulus, and flexural strength, whereas MPP/TPU blends exhibit higher energy absorption and impact strength. This study is expected to produce optimal products with the preferred continuous and dispersive phases for end users, designing multiple and compatible functionalities of blends.

“…In addition to a polymer container, temperature control equipment can be used at a needle, as well as in a spinning zone and/or a collector to facilitate fiber formation and deposition. 36,55 There are two main issues with melt electrospinning: very low conductivity of melts and higher viscosity of melts compared to polymer solutions. An absence of conductivity does not allow the wiping motion that elongates the jet in solution electrospinning.…”

Self-cleaning surface is potentially a very useful addition for many commercial products due to economic, aesthetic, and environmental reasons. Super-hydrophobic selfcleaning, also called Lotus effect, utilizes right combination of surface chemistry and roughness to force water droplets to form high contact angle on a surface, easily roll off a surface and pick up dirt particles on its way. Electrospinning is a promising technique for creation of superhydrophobic self-cleaning surfaces owing to a wide set of parameters that allow effectively controlling roughness of resulted webs. This article gives a brief introduction to the theory of super-hydrophobic selfcleaning and basic principles of the electrospinning process and reviews the scientific literature where electrospinning was used to create superhydrophobic surfaces. The article reviewed are categorized into several groups and their results are compared in terms of superhydrophobic properties. Several issues with current state of the art and highlights of important areas for future research are discussed in the conclusion. V C 2012 Wiley Periodicals, Inc.
