AMINOLYSIS OF POLY(ETHYLENE TEREPHTHALATE)

Sen'i Gakkaishi, 1975
Reactivities of amines and reaction regions in aminolysis of PET fibers were investigated by using various primary amines, ammonia, and hydrazine. Aminolysis occurs randomly and the reaction rate is decreased in the order of MA>HH>EA>n-PA>n-BA>EDA>AM>MEA>iso-BA>sec-BA.

Leaf‐Inspired Eutectic Skin With Extreme Fatigue Resistance and Robust Wet Adhesion for Amphibious Epidermal Electronics

Advanced Materials, EarlyView.
Inspired by Acorus calamus leaves, a heterogeneous eutectic skin integrates an aligned fibrous network within a hydrophobic eutectogel matrix. This hierarchical architecture triggers strain‐induced crystallization to achieve exceptional mechanical toughness and durable wet adhesion.

Development and characterisation of injection moulded, all-polypropylene composites

, 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).
