A Harvard study describes a new way to process natural rubber that preserves its long molecular chains while mixing in strength-endowing particles. The resulting stiff and durable material could lead to strong, long-lasting, natural-rubber composite tires. https://t.co/iNgEXmmU1z
@ZacconeAlessio Your model uses an aggregate size (r) measured from TEM. But at percolation, these aggregates are in contact and form larger agglomerates. Should the same (r) be used? Or does it need to be redefined, given that the agglomerate 'size' changes as more filler is added.
Reducing hysteresis in rubber can translate to real energy savings, but particle reinforcement often increases energy loss. We show that long chains + structured silica break the trend, shifting composite architecture to unlock more efficient elastomers.

Powder of silica is structured—primary particles, aggregates, agglomerates.
This paper shows that the composite of silica aggregates and long natural rubber chains has low hysteresis while maintaining stiffness.
@ZacconeAlessio Thank you for the recommendation! We didn't measure the distinct aggregate sizes, but applying your relation to our data is definitely on the agenda. I am curious: how would you adapt the aggregate size parameter for a percolated network where the fillers are in contact?
This discovery wouldn't be possible without @ChenghaiLi3 , Masako, Mikaya, @ykutsovsky, @zhigangsuo. @ACSPublications
Special shoutout to undergrads Masako and Mikaya, who joined us as part of their ES91R project. Never too early to start research!

Preserving long rubber chains unlocks performance that conventional processing compromises!
In our latest @PNASNews paper, we show that avoiding mastication shifts silica-reinforced rubber into a regime of toughness and stiffness seldom observed.

The MWM Lab at Nanyang Technological University, is recruiting PhD students interested in topology-designed polymers: exploring how polymer structure and network architecture control mechanical performance, durability, and circularity (recyclable & biodegradable systems).
Our paper in celebration of Prof. Michael Rubinstein on his 70th birthday is online. Carbon black reinforced natural rubber is everywhere in daily life. Conventional high-intensity mixing processes cut long rubber chains and reduce the mechanical performance. Here, we demonstrate that preserving long rubber chains greatly amplifies toughness while maintaining modulus. Check out the paper for details. Great thanks to all coauthors! @MWM_Tan@XianyangB@GuodongNian@ykutsovsky@zhigangsuo
