Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Lignin dispersion in polybutadiene rubber (BR) with different mixing parameters

open access: yes
There is a strong need to replace carbon black and silica as a reinforcing filler in rubber industry. Lignin is a promising option as a replacement, because of its wide availability, complex chemistry and sustainable source.

Polybutadiene-g-polypentafluorostyrene as a coupling agent for lignin-filled rubber compounds

open access: yes, 2014
This study investigated the role of polybutadiene-g-polypentafluorostyrene (PB-g-PPFS) as a coupling agent between lignin and styrene butadiene rubber (SBR) in preparation of compounds with higher mechanical strength and lower viscoelastic loss.

Chiral Morphing of Liquid Crystal Polymer Networks

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
This paper reviews how macroscopic chirality spontaneously arises from liquid crystal polymer materials. It describes how alignment is utilized to create the mechanical anisotropy, geometric misorientation and asymmetry that leads to chiral shape morphing, how shape selection between helicoids and helices arises, the techniques used to prepare these ...

A Peroxide Curing Butyl Rubber

open access: yes, 1969
The reactions of peroxides with polymers have been studied for some time. They form an extensive part of vulcanization technology. Two types of reactions are generally recognized, those leading to crosslinking between polymer chains and those leading to ...

Dynamic Testing of Automotive Rubber Parts by the Resonant Beam Tester. Effect of Polymer, Deflection, Age, and Temperature on Dynamic Rate

open access: yes, 1964
When the recipe is basically the same, different polymers differ in dynamic rate and damping. Ethylene—propylene terpolymer, SBR, neoprene, and butyl gave higher dynamic rate and higher damping than natural rubber, polyisoprene, and the blend of ...

Polybutadienes of Controlled Cis, Trans and Vinyl Structures

open access: yes, 1959
The physical properties of polybutadiene vulcanizates have been measured as a function of polymer microstructure. Although the over-all properties of any one polybutadiene are determined by the relative ratio of cis, trans and vinyl units in the polymer ...

The Migration of Extender Oil in Natural and Synthetic Rubber, III. Relative Contributions of Principal Structures in Aromatic Fractions to Diffusion

open access: yes, 1969
Migration in rubber is a general phenomena of practical importance. A basic program using radiotracers was undertaken to help understand this migration and establish a rating system to allow the compounder to predict the behavior of a given oil from its ...
