Reactive melt processing of poly(ethylene terephthalate) waste into calcium terephthalate

open access: yeseXPRESS Polymer Letters, 2021
Recycling of waste poly(ethylene terephthalate) (PET) has attracted much attention in recent years because of the pressure from the environment. However, the cost-effective conversion of waste PET into value-added products by ecofriendly methods remains ...

Enhanced Poly(ethylene terephthalate) Hydrolase Activity by Protein Engineering

open access: yesEngineering, 2018
Poly(ethylene terephthalate) hydrolase (PETase) from Ideonella sakaiensis exhibits a strong ability to degrade poly(ethylene terephthalate) (PET) at room temperature, and is thus regarded as a potential tool to solve the issue of polyester plastic ...

Crystallization kinetics of poly(lactic acid)-talc composites [PDF]

open access: yes, 2011
The crystallization kinetics of Poly(lactic acid) / talc composites were determined over a range of 0 wt.% to 15 wt.% of talc. Talc was found to change the crystallization kinetics.

A study of all-polymer composites: all-poly(ethylene terephthalate) and all-poly(p-phenylene terephthalamide) [PDF]

open access: yes, 2009
PhDComposites are normally composed of two distinct phases: reinforcement and matrix. In recent years, a new class of “self-reinforced” polymer composites or “all-polymer” composites, which are based on similar or identical materials for both ...

Development and characterisation of injection moulded, all-polypropylene composites [PDF]

open access: yes, 2012
In this work, all-polypropylene composites (all-PP composites) were manufactured by injection moulding. Prior to injection moulding, pre-impregnated pellets were prepared by a three-step process (filament winding, compression moulding and pelletizing).
