Stimuli‐responsive hydrogels: An intelligent tool for wound management

Interdisciplinary Medicine, EarlyView.
For chronic and complex wounds, this review focuses on intelligent hydrogels capable of responding to wound microenvironmental cues (e.g., pH, enzymes) or external stimuli (e.g., light, electricity). These advanced materials enable the dynamic regulation of drug release and real‐time monitoring of healing progression, thereby offering innovative ...

Modeling Fiber Dispersion in a Single‐Screw Extruder for Long Fiber‐Reinforced Thermoplastics

Polymer Composites, EarlyView.
Fiber dispersion throughout the screw channel ABSTRACT Understanding the mechanics of fiber attrition during the plasticizing process is important in predicting the strength of long fiber‐reinforced thermoplastics (LFT) composites. Fiber dispersion has been found to impact fiber damage during processing and therefore final fiber length in the final ...

Poly(L‐Lactide‐Co‐ε‐Caprolactone)/glass Fiber Composites: Toward Improved Mechanical Properties of Polylactide‐Based Composites

Polymer Composites, EarlyView.
Enhanced impact strength in PLLA‐based composites via ε‐caprolactone incorporation in the matrix. ABSTRACT Inherent brittleness and limited toughness of polylactide (PLA) restrict its use in high‐performance applications. To overcome these limitations, poly(L‐lactide) (PLLA) is often blended with more ductile thermoplastics or chemically modified ...

Effects of Polyamide‐6 Bulk Plasma Treatment on Morphology, Crystallinity and Mechanical Properties of Microfibrillar Composites

Polymer Composites, EarlyView.
Microfibrillar composite containing highly oriented, plasma‐treated PA6 microfibrils embedded within the polymer matrix. ABSTRACT Plasma treatment is often used to alter chemical surface characteristics of fibers or polymers, improving dispersion of components and interfacial adhesion between incompatible constituents in composites.

On the Mechanical and Thermal Behavior of PLA, PBAT, and PHBV‐Based Ternary Blends and the Effect of Short Flax Fibers as Reinforcing Agents

Polymer Composites, EarlyView.
Preparation and testing of biodegradable polymer ternary blends and composites with short flax fibres. ABSTRACT Bioplastics offer environmental benefits but they are costly and exhibit lower mechanical and thermal performance compared to fossil‐based counterparts. Poly(butylene adipate‐co‐terephthalate) (PBAT) exhibits high ductility but relatively low

Immiscibility phenomenon in low density branched polyethylene, PEED, films in blown film extrusion process

CT&F - Ciencia, Tecnología y Futuro, 2000
The immiscibility in branched low-density polyethylene film was researched using techniques of instrumental analysis (FTIR, DRX, DSC, TGA, SEC-GPC, SEM-EDX) and rheometry (DMA, Capillary Rheomether). It was determined that immiscibility occurs when there are microentities generated by an undesirable polymer found in a low proportion in the mixture ...

Using Secondary Air Cooling in Blown Film Extrusion: Concept Design and Experimental Study

, 2019
The characteristics and the quality of a blown film are strongly influenced by the stretching and simultaneous cooling of the molten polymer within the bubble formation zone. Moreover, the output rate of the process is generally limited by the cooling rates and the stability of the bubble.
