Polyethylene terephthalate textile heart valve: How poly(ethylene glycol) grafting limits fibrosis

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2022
AbstractTranscatheter aortic valve replacement (TAVR) is an alternative technique to surgical valve replacement for over 300,000 patients worldwide. The valve material used in the TAVR is made of biological tissues, whose durability remains unknown. The success of the TAVR favors the research toward synthetic valve leaflet materials as an alternative ...

3D Printing of Polyethylene Terephthalate Glycol–Sepiolite Composites with Nanoscale Orientation

ACS Applied Materials & Interfaces, 2020
A fused-deposition modeling (FDM) 3D-printed polyethylene terephthalate glycol (PETG)-sepiolite composite showed effective synergetic mechanical reinforcement in tensile testing compared to an injection-molded composite. The results showed that the addition of 3 phr sepiolite improved the tensile strength of 3D-printed PETG samples by 35.4%, while the ...

Incorporation of polyethylene glycol into polyethylene terephthalate towards blue emitting co-polyester

Materials Letters, 2016
In this work, fluorescent co-polyester was prepared by incorporating polyethylene glycol (PEG) segment into backbone of polyethylene terephthalate (PET). The crystalline structures and fluorescence properties of obtained PET-PEG copolymers were systematically studied. It was found that the crystalline behaviour of PET was significantly alternated after

Biodegradability of Polyethylene terephthalate Copolymers with Polyethylene glycols and Polytetramethylene glycol

Polymer International, 1996
Poly(ethylene terephthalate) copolymers were prepared by melt polycondensation of dimethyl terephthalate and excess ethylene glycol with 10-40 mol% (in feed) of poly(ethylene glycol) (E) and poly(tetramethylene glycol) (B), with molecular weight (MW) of E and B 200-7500 and 1000, respectively. The reduced specific viscosity of copolymers increased with

Electrochemical Production of Glycolate Fuelled By Polyethylene Terephthalate Plastics with Improved Techno‐Economics

Small, 2023
AbstractElectrochemical valorization of polyethylene terephthalate (PET) waste streams into commodity chemicals offers a potentially sustainable route for creating a circular plastic economy. However, PET wastes upcycling into valuable C2 product remains a huge challenge by the lack of an electrocatalyst that can steer the oxidation economically and ...

A study on the biodegradability of polyethylene terephthalate fiber and diethylene glycol terephthalate

Journal of Applied Polymer Science, 2004
AbstractThe degradation of diethylene glycol terephthalate (DTP) and polyethylene terephthalate fiber (PET fiber) by microbes and lipase was studied. The HPLC method was used to determine the degradation ratio and degradation rule of DTP. Greater than 90% DTP was degraded by microbes in 24 days and 40% by lipase in 24 h.
