FIBRILLATION OF FLAX AND WHEAT STRAW CELLULOSE: EFFECTS ON THERMAL, MORPHOLOGICAL, AND VISCOELASTIC PROPERTIES OF POLY(VINYLALCOHOL)/FIBRE COMPOSITES

BioResources, 2011
Nano-fibrillated cellulose was produced from flax and wheat straw cellulose pulps by high pressure disintegration. The reinforcing potential of both disintegrated nano-celluloses in a polyvinyl-alcohol matrix was evaluated.

Study on Poly(Vinyl Alcohol) CopolymersBiodegradation [PDF]

Memoirs of the Scientific Sections of the Romanian Academy, 2015
In the study the biodegradability of some poly(vinyl alcohol)-g-aspartic acid copolymers was investigated, using Trichotecium roseum fungus. The biodegraded samples were examined after established days of inoculation (3–21 days).

Polyvinyl alcohol–boronate gel for sodium hydroxide extraction

, 2018
Gels formed from commercially available polyvinyl alcohol (PVA) and 1,4-benzene diboronic acid (BdBA) in DMSO absorb NaOH efficiently from a bulk aqueous solution decreasing its pH.

Rapid Photogelation of Low‐Concentration Polymer Solutions via Photodimerization of o‐Ethylnitrobenzene

Advanced Science, EarlyView.
Upon UV irradiation, flexible and tough hydrogels are formed rapidly (>0.5 s) from dilute (>0.5 wt%) solutions of o‐ethylnitrobenzene–modified PVA. At ∼1.5 wt%, the hydrogels withstand up to 10 MPa compression, remain handleable even after 200‐fold swelling.

Strength-Deformation Characteristics of Polyvinyl Alcohol/Polyvinyl Acetate Composite Films

Improvement of deformability of rigid polymers may be reached by forming its blends with certain more compliant polymers. Polyvinyl acetate (PVAc) was chosen as this yielding counter component for blends with rigid polyvinyl alcohol (PVA). Blends of PVA/

Root‐Inspired Microneedle Patch With Interlocked Rigid‐Soft Architecture for High Tissue‐Adaptiveness

Advanced Science, EarlyView.
A root‐inspired microneedle array patch uses lattice‐based mechanical interlocking to unite rigid microneedles with a flexible substrate. The interlocked rigid–soft architecture improves interfacial bonding, supports stable adhesion on curved and wet tissues under dynamic motion, and provides a versatile platform for robust biointerfacing and future ...

Crease-recovery of polyvinyl alcohol fibres

, 1962
Polyvinyl alcohol and cellulose are hydrophilic polymers whose fibres exhibit low crease-recovery. A comparison of their molecular structures, however, shows that the creasing problems and their remedy are entirely different.

Single‐Dose TACE‐Like Injection of Sustained‐Release Panobinostat/IL‐12 Polymeric Microparticles is Effective in Preclinical Liver Cancer Models

Advanced Science, EarlyView.
A novel PLGA/PBAE polymer microparticle platform revolutionizes intermediate‐stage liver cancer treatment by co‐delivering panobinostat and IL‐12 via a single TACE‐like injection. This sustained‐release system overcomes tumor immunosuppression, triggers robust innate and adaptive immune responses, and establishes tertiary lymphoid structures ...

Polyvinyl alcohol: materials, processing and applications

, 2009
For a number of years, plastic wastes have been accumulating at such a rate that there are now huge environmental concerns with their disposal. Options such as landfill and incineration have not been well received by the public, or indeed government ...
