Cyclic Processability of Functional Liquid Crystalline Epoxy Networks via Dynamic Ester Bonding

Journal of Applied Polymer Science, EarlyView.
This work reports the successful reprocessing of liquid crystal epoxy networks through two distinct modes—welding of clean breaks and reconstitution from shredded material—without significant loss of functionality. Thermal and mechanical characterization shows stability in the shape memory behavior and glass transition temperature over multiple ...

From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

How Circular Innovation Is Learned: A Process Study of Modularity‐Based Initiatives in Industrial Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular innovation (CI) research has identified a wide range of circular strategies and design approaches, yet offers limited insight into how CI evolves as a learning process within firms and which governance mechanisms guide this progression. Drawing on organizational learning (OL), this study examines how exploration and exploitation shape
