Herein, poly(amic acid) (PAA) was synthesized using 4,4’-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) as a dianhydride and 2,2-bis(3-aminophenyl)hexafluoropropane (6FAm) and 2,2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane (6FAm-OH) as diamines. Poly(vinyl alcohol) (PVA) at various contents (0–5.0 wt%) was blended with PAA to prepare a composite material. Then, colorless and transparent polyimide (CPI) composite films were prepared by applying various stages of heat treatment using the PAA/PVA blend film as a precursor. These film-type composites were immersed in water to completely

The objective of the present study was to develop an orally disintegrating film (ODF) for a poorly water-soluble drug, phenytoin (PHT), using the cosolvent solubilization technique to achieve the amorphization of the drug, followed by the preparation of ODFs. Eleven formulations were prepared with different polymers, such as polyvinyl alcohol (PVA) and high methoxyl pectin (HMP) by the solvent casting method. The prepared films were subjected to characterization for weight variations, thickness, surface pH, disintegration time and mechanical strength properties. Then, differential scanning cal

A new type of nano-composite film was prepared from polyvinyl alcohol, Ni2+-montmorillonite (Ni2+-MMT), defoamer, a levelling agent and a plasticizer. Its thermal characteristics were studied by Differential Scanning Calorimetry (DSC). The intermolecular interactions were measured by Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS), and the tensile strength (TS) and elongation at break (%E) were measured. The microstructures were studied by X-ray diffraction (XRD) and atomic force microscopy (AFM). FT-IR and XPS spectra indicated that cross-linking has

Polyvinyl alcohol (PVA) is well-known in the packaging industry, especially in the food and medical fields with the ability to be completely biodegradable and easily soluble in cold water therefore products made from it are the environmentally friendly materials. However, the disadvantages of this polymer as quick dissolubility in water, poor moisture retention, weak mechanical properties reduce its applications. In this study, PVA, reinforced by “green” components at the nanometer-level such as nanocellulose fibers (CNF), graphene oxide (GO) nanosheets showed improvements in properties. Mecha

AbstractTrash has always been a problem for the world. Trash are items that no longer have any use and havebeen thrown away by their owner(s). Current estimations show that Indonesia produces 85.000 tonsof daily trash, with further estimations showing an increase up to 150.000 tons of trash per day, a76% increase, by the year 2025. Water-soluble films are films that can dissolve or degrade when theycome into contact with water, made from polyvinyl alcohol (PVA) polymers. From the year 2012, thismaterial has been used in America detergent packaging, spa cosmetics, and many others. Water-soluble

Abstract:We report on the preparation of conjugated polymer nanofibers via template-synthesis. A femtosecond laser machined fused silica template, with a micro-patterned array of high-aspect ratio surface nanopores, was first spin-coated with a polyvinyl alcohol (PVA) solution to form a water-soluble release layer. The PVA-lined template was then coated with a conjugated poly(3-hexylselenophene) (P3HS) – solvent solution. The solvent was allowed to dissipate, and the resulting {template / PVA liner / conjugated P3HS film} stack was then submerged in water to dissolve the PVA and release the co

This chapter reports the determination of eco-friendly, bio degradable polymer composite film by amalgamation of an edible, water soluble polysaccharide named as Carrageenan and based on PVA (polyvinyl alcohol). Polymers are macromolecules with long repeating chains of monomers made by the process of polymerization. Polymers possess multi-functionality and better film-forming capabilities, which could significantly improve protective barrier properties. Natural polymers are one among the major classes of polymers based on their origin. This class includes proteins, cellulose, poly peptides, an

The following article represents the research on the elaboration of biodegradable films for environmentally friendly packaging based on polyvinyl alcohol, corn starch, glycerin, and borax. Growing consumption of packaging results in greater waste; the biggest part of which comprises problematic plastic packaging that is difficult and expensive to recycle. The majority of biodegradable packaging materials have insufficient technological characteristics. It is due to that the development of composite compositions based on inexpensive raw materials is a necessary condition to extend the range of

Abstract Scale control at high LSI and high pH without acid feed is difficult to achieve. The problem dramatically increases in cooling towers when PVC tower film fill is used. Compounds that are able to enhance the performance of typical scale inhibitors have been developed. When topped off with these enhancing compounds, typical scale inhibitors are able to control calcium carbonate and silicate - related scale formation on metal heat exchanger and cooling water tower film fill surfaces in cycled waters having high LSI (~3.0), high alkalinity (500-700 mg/L as CaCO3), and high pH (8.5 or high

Abstract Developing a cost-effective fabrication method for devices containing metal channels with surface features on the submillimeter scale is essential for the development of novel, high efficiency micro-reactors and heat sinks. Traditional methods are limited by their high cost, low geometric accuracy, high energy consumption, and long processing times. This study presents a low-cost additive manufacturing method using twin wire arc spray to make surface features at the sub-millimeter scale.
