We will discuss a novel non-contact removal technique of optical fiber coating in continuous and uninterrupted manner with hot air stream. We observed little degradation of the tensile strength of the optical fiber after removing the protective polymer coating and the mean breaking tensile strength of the stripped optical fiber using non-contact removal method was 5.1GPa. key words: non-contact...

Polypropylene (PP) has poor adhesion to metals and other surfaces for its chemical structure. Hence, chemical modification of PP is necessary for metal surface coating application. In this research, grafting of maleic anhydride (MA) onto co(propylene-b-ethylene) in the presence of a dicumyl peroxide (DCP) was accomplished in a single screw extruder. Characteristics of the modified polymer were ...

Fine Dechlorane (DCR) particles with an average size of 12 Am were successfully encapsulated with poly(methyl methacrylate) (PMMA) and poly(1-vinyl-2-pyrrolidone) (PVP) polymers via in situ dispersion polymerization in supercritical carbon dioxide (scCO2). Adjusting the process parameters can control the coating thickness, surface morphology, and degree of particle agglomeration. A uniform thin...

knowledge of physiological and environmental factors is important for foragegrass production. festuca ovina is a grass species adapted to azerbaijan region climate,iran. this species is a valuable source for forage production and soil conservation.nitrogen (n), phosphorus (p) and potassium (k) are three most important plant nutrients.the aims of present study were to investigate the effects of ...

Active release antimicrobial coatings for medical devices have been developed to prevent and treat biofilm implant-related infections. To date, only a handful of coatings have been put into clinical use, with limited success. In this study, a novel antimicrobial compound was incorporated into a silicone (polydimethylsiloxane or PDMS) polymer to develop a novel active release coating that addres...

the main objective of this study was to prepare colon-specific pellets of budesonide, using pectin as film coating. pellet cores of budesonide were prepared by extrusion / spheronization technique. pectin, in different ratios was combined with eudragit rs30d, eudragit ne30d or surelease to produce film coating. the dissolution profiles of pectin coated pellets were investigated in ph of 1.2 (2 ...

Thin films of a conjugated polymer Poly [2-methoxy-5-(3’,7’-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMO-PPV) were prepared from chloroform, 1,2dichlorobenzene and toluene solutions by spin coating technique on quartz substrates. Absorption and photoluminescence (PL) spectra of the polymer thin films prepared from different solvents were measured. The UV-vis absorption and PL spectra of MDMO-...

Progress on these topics is occasionally updated in Coating Materials News (CMN) issues since polymer substrates are being used with greater frequency in displays, solar panels, laminated window glazing, reflectors for illumination, and other optical applications. Injection molded or form cast polymer parts are now mass-produced as economical and light-weight replacements for glass parts. The s...

The present invention is directed to a method for powder coating a metal substrate using a low-melt polyamic acid (PAA) polymer that readily imidizes to polyimides. These low-melt PAAs have been shown to be useful in resins applied as powder coatings to metal surfaces. The resin includes an end-capping material capable of providing crosslinking functionality to at least one end of the low-melt ...
