Effect of PBAT content on performance of PLA based degradable blend slice and composite meltblown nonwovens

Cailiao gongcheng
Taking polylactic acid (PLA) as matrix, poly(butylene adipate-co-terephthalate) (PBAT) as toughening agent and polyethylene glycol (PEG) as plasticizer and compatibilizer, PLA/PBAT/PEG blends with different PBAT contents were prepared by melt-blending ...

PREPARATION AND CHARACTERIZATION OF EXTRUDED PBAT/ORGANOCLAY FILMS

Proceedings of the 4th Brazilian Conference on Composite Materials, 2018
Abstract In this paper, we investigate the influence of organoclay identity and content on the tensile properties, gas permeation characteristics and biodegradation of extruded poly(butylene adipate)-co-(butylene terephthalate) (PBAT)/organophilic clay films. Cloisite C10A and C30B organoclays were used as fillers with loading levels of 0, 1 and 3 wt%

The effect of rotor speed on EVA/PBAT blend using Twin screw extruder and foamability of EVA/PBAT blend

IOP Conference Series: Materials Science and Engineering, 2020
Abstract This research is aimed to study EVA/PBAT blends with various EVA and PBAT composition and screw speeds. At PBAT contents 40% EVA and PBAT present as co-continuous phase morphology. The morphology did not change due to screw speed.

Compatibilization and Reinforcement of PHB/PBAT Blends via Sequential Blending of Surface‐Modified Cellulose

Polymer Engineering &Science, EarlyView.
Sequential blending improved the mechancial properties of PHB/PBAT/cellulose composites as compared to the one‐step batch mixing method. ABSTRACT Polyhydroxybutyrate (PHB) is a natural and biodegradable polymer generated by bacteria. While its applications to potentially replace petroleum‐based plastics are severely limited due to its brittleness and ...

Biodegradation of PBAT and PHB/PBAT by Aspergillus and Purpureocillium isolates

Abstract In recent years blends and composites of biodegradable polymers have been developed as alternatives to petroleum-based plastics. Polybutylene adipate terephthalate (PBAT) and polyhydroxybutyrate (PHB) are examples of polymers that received much attention due to their interesting mechanical properties.

Melt and Cold Crystallization Behavior of Poly(Lactic Acid) With Different Molecular Weights and Its Influence on Mechanical, Viscoelastic, and Tribological Properties

Polymer Engineering &Science, EarlyView.
Modifying the crystallinity of PLA and its properties through annealing. ABSTRACT The melt and cold crystallization behavior of two PLA grades with different molecular weights was investigated using various DSC analyses. During isothermal melt crystallization, PLA with lower molecular weight exhibited faster crystallization kinetics across different ...
