“…Numerous researchers endeavored to develop the blends with the synthetic peptides; poly(γ-benzyl L-glutamate) with Poly(ethylene glycol) [18], Poly(butyl acrylate-comethylmethacrylate) [19], poly(vinyl alcohol) (PVA) [20], phenolic resin [21] and polystyrene derivatives [22].Polytyrosine (PTyr) blended with poly(4-vinylpyridine) (P4VP) [23], and K Murata et al [24] pondered the blend of polyglycine (PG)/ poly(L-valine) (PLV) with high miscibility. Several methods have been practiced to review the miscibility of two or more synthetic polymers, but, the miscibility of synthetic bio-mimetic polymers with synthetic ones is feebly understood.…”

The medleys of the plastic-derived polypeptide with commercially available polymers believably the suitable candidate for pharmaceutical and biomedical importance. The current research is focussed on the synthesis of a novel plastic-mimetic polypeptide (PLP), poly(IPAVG) by the solution phase method (where I, P, A, V, and G represent Isoleucine, Proline, Alanine, Valine, and Glycine, respectively). The miscibility attributes of PLP/polyvinyl alcohol (PVA) and PLP/ hydroxypropylmethylcellulose (HPMC) blends were examined by viscometry and by other advanced analytical tools for different weight proportions. It is shown by the viscometry that the PLP/HPMC and PLP/PVA form an immiscible blend system at 10 ο C and further, the FTIR spectra of poly (IPAVG) /HPMC and poly (IPAVG) /PVA blend membranes manifest the lack of intermolecular interactions. DSC results proved the dual Tg for one blend proportion and lower Tg values for all other blend systems. The thermal property of the blends with different compositions was evaluated by thermogravimetric analysis (TGA). The TGA results showed that the blends possess inferior thermal stability to the native ones. The surface morphology was analyzed by SEM indicated the heterogeneity and X-ray diffraction (XRD) revealed the absence of any change in crystallinity advocated the immiscibility of the blends. Further, we ventured to prepare the non-woven fabrics from the solutions of 1-10 wt% concentrations at the voltages within 20-30 kV by electrospinning. The droplet formed at the spinneret failed to reach the collector plate, and consequently, no films developed for the collector device.

“…However, if the polymers are compatible, interactions in the blends will result in clear differences in the spectra [22] . In this sense, infrared spectroscopy (FT-IR) is a useful technique in studying polymer blends, especially blends with hydrogen bonding interactions [23,24] .…”

Chitosan/poly(methyl methacrylate-co-butyl methacrylate) (PMMA-co-BMA) blends were prepared via a solution blending method in the presence of formic acid. The compatibility of the bioblends was studied by different methods, such as Fourier transform infrared and Raman spectroscopy, micro-Raman imaging, thermogravimetric analyses, differential scanning calorimetry and scanning electron microscopic analysis. According to the obtained results, it has been concluded that the PMMA-co-BMA/chitosan bioblends are compatible in all the studied compositions. Specific interactions between carbonyl and methyl groups of the PMMAco-BMA structure and methyl, amine and amide groups of chitosan are responsible for the observed compatibility. INTRODUCTIONConcerns about environmental problems such as global warming, pollution of natural resources, renewable energy use and cost of synthetic polymers have motivated an intense research of sustainable polymer systems where at least one component is biodegradable or biobased [1] . The commercial importance of polymers also have increased the need of discover of new materials with specific properties and applications; for this purpose new polymers have been synthesized and chemical modifications in conventional polymers have also been proposed, but these methods are more complicated [2,3] . However, the mixture of two or more polymers, giving rise to a polymer blend, seems to be an economical method to obtain new polymeric materials with desirable properties, without the need of synthesizes specialized polymer systems [4,5] .

“…Poly(vinyl alcohol) (PVA) is a non-toxic, plasticizer, water soluble, biocompatible, and biodegradable synthetic polymer, which is widely used in biomedical fields [18][19][20][21][22][23][24][25][26][27][28][29][30] . Chemically crosslinked PVA hydrogels have received increasing attention in biomedical and biochemical applications, because of their permeability, biocompatibility, and biodegradability [31][32][33][34] .…”

This study focuses on the fabrication of poly(vinyl alcohol)/ poly(vinyl pyrrolidone)-Iodine nanofibers via electrospinning. Electrospun fibers were characterized by FT-IR, DSC and SEM techniques. DSC results indicated that the thermal stability of nanofibers were improved after the addition of chitosan and poloxamer 188. SEM images showed that the spongiform structure is much more compact and fibrous in the case of added chitosan, with an average fiber diameter of 374 nm, whereas the addition of poloxamer 188 resulted in a more porous and beaded composition, with average fiber diameter of 489 nm.
