In this study, the effect of hygrothermal conditioning on the moisture diffusion properties of the fabric composite (glass fiber/epoxy resin) was investigated. The water uptake of the specimens conditioned in humid environment at different relative humidities (0, 60 and 96 % r.h) at constant temperature (60°C) was evaluated by weight gain measurements. The moisture diffusion properties of the f...

Abstract We report on our newest studies of electrically conductive interpenetrating polymer networks (IPNs) for application in temperature micro sensors. manufactured polymeric structures glass with a pattern generator by exposing combination Novolak and Terthiophene doped copper(II) perchlorate UV laser. assessed the effects prolonged loads structures’ impedances range 30 to 130 °C. Such poly...

A fibre glass reinforced polymer was developed, using epoxy resin as the matrix material and E-glass reinforcement, by hand laying method. Different set of composite were produced varying weight percentage (wt%) addition reinforcement to follows 10%, 20%, 30%, 40% 50%. The polymeric so subjected various mechanical property tests hardness, tensile, impact, tests. hardness test conducted TQ SM100...

Glass transition temperature is one of the most important characteristics to describe behavior polymeric materials. When a material goes through glass transition, conformational entropy increases, which affects phonon density states. Amorphous materials invariably display low-frequency Raman features related states resulting in broad disorder band below 100 cm−1. This includes Boson peak and sh...

Particulate reinforcement of polymeric matrices is a powerful technique for tailoring the mechanical and degradation properties bioresorbable implant materials. Dispersion inorganic particles critical to achieving optimal properties, however established techniques such as twin-screw extrusion or solvent casting can have significant drawbacks including excessive thermal particle agglomeration. W...

The recent commercial success of foldable smartphones is indebted in part to integration ultra-thin glass (UTG) into the flexible display modules. To endow with such a foldability, while keeping its merits over polymeric materials, tons complicated issues need be resolved addition thickness reduction. Since UTG subjected repeated deformations during service as cover window, extra care required ...

In this work, the use of foam-like glass-ceramic scaffolds as trabecular coatings on ceramic prosthetic devices to enhance implant osteointegration is proposed. The feasibility of this innovative device was explored in a simplified, flat geometry: glass-ceramic scaffolds, prepared by polymeric sponge replication and mimicking the trabecular architecture of cancellous bone, were joined to alumin...

The photophysical properties such as singlet absorption, molar absorptivity, fluorescence spectra, dipole moment, fluorescence quantum yields, fluorescence lifetimes and laser activity of 1,4-bis (β-Pyridyl-2Vinyl) Benzene (P2VB), 2,5-distyryl-pyrazine (DSP) and 1,4-bis(2-methylstyryl)benzene(MSB) diolefineic laser dyes have been measured in different restricted hosts. (P2VB), (DSP) and (MSB) a...

This study describes a new means to conduct molecular recognition-based analysis using mass spectrometry. Taking advantage of the unique characteristic of the absorption capacity of the TiO(2) sol-gel material in the UV region, a TiO(2) sol-gel-deposited thin film was employed as the sample substrate to assist in UV laser desorption/ionization of analytes. Sol-gels are polymeric materials that ...

In a polymeric material near its glass transition temperature, segmental dynamics of a given spatial region may differ considerably from that of neighboring regions without apparent structural origin, analogous to the supercooled liquid state of low molecular weight glass formers. Given that the supercooled liquid state is a (metastable) equilibrium state, spatial variations in dynamics are exp...
