Download scientific diagram | Thermogravimetric analysis (TGA) of PS, PE, PP, and PET plastic waste. from publication: Catalytic Pyrolysis of Plastic Waste: Moving Toward Pyrolysis Based ...

TGA curves of PS and PET. Zinc bulk catalysts (Zn, ZnO and ZnCl2) were used for the thermo-catalytic pyrolysis of EPSW and were found with high activity and selectivity of products....

Thermogravimetric analysis (TGA) is a common method to study the kinetics of poly-mer degradations. Differential scanning calorimetry (DSC) is also employed to elucidate the decomposition steps observed in the TGA data.

2021年10月1日 · This mini review identifies several thermogravimetric analysis (TGA)-based methods for the identification and quantification of different microplastics in both proof-of-concept studies and environmental samples, and highlights method-specific limitations associated with their application.

2021年12月14日 · The present study aims to determine the thermodynamic parameters of the degradation process of conventional thermoplastics (polystyrene (PS), polyethylene terephthalate (PET), high-density polyethylene (HDPE), polypropylene (PP) and polyvinyl chloride (PVC)) from the study of their chemical kinetics by thermogravimetric analysis (TG).

2022年12月18日 · Thermogravimetric analysis is an effective way to quantify rates of devolatilization and several TGA curves at different heating rates and thermal schedule required to determine...

2005年4月15日 · In this study, the possibility that the presence of the clay causes some chemical changes in the degradation pathway of polystyrene nanocomposites was explored, using TGA/FTIR for the thermal degradation and in-situ characterization of the evolved products and also collection of the evolved products for identification by GC/MS and FTIR. 2.

A dynamic TGA method was used to study the effect of the molecular weight of welldefined polystyrene samples as well as the effect of heating rate and sample weight on the kinetic parameters of the thermal decomposition.

2014年3月1日 · The pyrolysis behaviors of PE, PS, PVC and their blends were studied by TG/FTIR. The TGA results showed that the thermal stability increased flowed by PVC, PS and PE. The pyrolysis of PE was accelerated when mixed with PS. Both the pyrolysis of PE and PVC were retarded when mixed together and the pyrolysis of …

2013年10月10日 · This study addresses the thermal stability and degradation path of symmetric and asymmetric PS- b -PMMA block copolymers, widely employed to generate templates for nanopatterned materials, and of the associated P (S- r -MMA) random copolymers, through a combination of TGA and TGA–GC–MS techniques.
