Surface Chemical Analysis of Plastic Materials by X‐Ray Photoelectron Spectroscopy: Understanding Weathering, Fragmentation and Contaminant Uptake in Marine Environments

Macromolecular Materials and Engineering, EarlyView.
This Perspective demonstrates how X‐ray photoelectron spectroscopy (XPS) uncovers surface chemical changes in plastics, providing insight into weathering‐driven fragmentation and contaminant adsorption. The Perspective underscores XPS's pivotal role in elucidating fragmentation mechanisms, predicting pollutant–plastic interactions, and guiding ...

Synthesis and properties of composites of starch and chemically modified natural rubber [PDF]

, 2004
A means is developed for forming polysaccharide-based composites with useful material properties through use of unmodified and chemically modified natural rubber latex (NRL). Starch was used as a model for polysaccharides.

Successive Mechanical Recycling of Poly(lactic Acid) by Injection Molding: Evolution of Molecular, Thermal, and Mechanical Properties

Macromolecular Materials and Engineering, EarlyView.
This study investigated how successive injection molding recycling affects the properties of poly(lactic acid) (PLA). Gel permeation chromatography showed a two‐thirds molar mass reduction after ten reprocessing cycles. Differential scanning calorimetry revealed lower glass transition and cold crystallization temperatures.

Biodegradable and non-retrogradable eco-films based onstarch?glycerol with citric acid as crosslinking agent [PDF]

, 2016
Biodegradable and non-retrogradable starch-glycerol based films were obtained using citric acid (CA) as crosslinking agent at 75 °C. This material allowed decreasing water vapor permeability (WVP) more than 35%, remained amorphous for at least 45 days as

Impact of Organic and Inorganic Fillers on the Performance of Ternary Biodegradable Poly(Butylene Succinate‐Co‐Butylene Adipate), Poly(Butylene Adipate‐Co‐Terephthalate), and Poly(3‐Hydroxybutyrate‐Co‐3‐Hydroxyvalerate) Blends

Polymer Composites, EarlyView.
Development of a ternary blend composite based on PBAT/PBSA/PHVB with improved mechanical properties. ABSTRACT This study explores a ternary biodegradable blend of bio‐based poly(butylene succinate‐co‐adipate) (bio‐PBSA), poly(butylene adipate terephthalate) (PBAT), and poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV).

Enzymatic degradation of starch thermoplastic blends using samples of different thickness [PDF]

, 2009
The material studied was a thermoplastic blend of corn starch with a poly(ethylene-vinyl alcohol) copolymer, SEVA-C. The influence of both the material’s exposed surface and enzyme concentration on degradation kinetics was studied.

Biodegradable Biocomposites of Isosorbide‐Plasticized Corn Starch Reinforced With Green Graphene: Enhanced Properties for Sustainable Applications

Polymer Composites, EarlyView.
Different properties of biocomposites based on TPS with isosorbide as a plasticizer and green graphene filler. ABSTRACT New biocomposites of corn starch plasticized with isosorbide and filled with two types of “green” graphene with different oxygen content, 1% (G99) and 8% (G92), were processed by melt blending.

How to combine a hydrophobic matrix and a hydrophilic filler without adding a compatibilizer – Co-grinding enhances use properties of renewable PLA-starch composites [PDF]

, 2012
In order to avoid the use of compatibilizers or plasticizers, co-grinding was performed to produce PLA – starch composite materials. Fragmentation and agglomeration phenomena were analysed to propose a production mechanism.
