The use of melt rheology and solution viscometry for degradation study of post-consumer poly(ethylene terephthalate): The effects of the contaminants, reprocessing and solid state polymerization

Autor: Lays B. Fitaroni, Éder C. Oliveira, Carlos Henrique Scuracchio, Sandra Andrea Cruz

Publikováno v: Polymer Testing. 60:236-241

Rheological measurements and intrinsic viscosity were performed to determine how the presence of contaminants, reprocessing and solid state polymerization (SSP) affects the degradation of post-consumer poly(ethylene terephthalate) (PET). First, post-

Barrier properties to surrogates of hydrogenated carbon nano-films deposited on PET by plasma-enhanced chemical vapour deposition

Autor: Sandra Andrea Cruz, Cristina Nerín, Yolanda Echegoyen, Éder C. Oliveira

Publikováno v: Food Additives & Contaminants: Part A. 31:1914-1927

Poly(ethylene terephthalate) resin was contaminated with a series of surrogates using a US Food and Drug Administration protocol. The contaminated samples were coated with two different kinds of hydrogenated amorphous carbon thin films (a-C:H): one w

Comparison between solid phase microextraction (SPME) and hollow fiber liquid phase microextraction (HFLPME) for determination of extractables from post-consumer recycled PET into food simulants

Autor: Éder C. Oliveira, Yolanda Echegoyen, Cristina Nerín, Sandra Andrea Cruz

Publikováno v: Talanta. 127:59-67

Hollow fiber liquid phase microextraction (HFLPME) and solid phase microextraction (SPME) methods for pre-concentration of contaminants (toluene, benzophenone, tetracosane and chloroform) in food simulants were investigated. For HFLPME 1-heptanol, 2-

Modification of clarified polypropylene by oxygen plasma to improve the adhesion of thin amorphous hydrogenated carbon films deposited by plasma enhanced chemical vapor deposition

Autor: Paulo Henrique Lopes Aguiar, Éder C. Oliveira, Sandra Andrea Cruz

Publikováno v: Polymer Engineering & Science. 53:1065-1072

Despite having many potential applications, polypropylene (PP) has limitations that may make its application difficult when there is a requirement for high transparency and low-gas permeability. In this context, studies have been reported about the u
