Overview


The research of the Rubinstein group is in the field of polymer theory and computer simulations. The unique properties of polymeric systems are due to the size, topology and interactions of the molecules they are made of. Our goal is to understand the properties of various polymeric systems and to design new systems with even more interesting and useful properties.

Our approach is based upon building and solving simple molecular models of different polymeric systems. The models we develop are simple enough to be solved either analytically or numerically, but contain the main features leading to unique properties of real polymers. Computer simulations of our models serve as an important bridge between analytical calculations and experiments.

Rubber that lasts longer

Journal Article Nature Sustainability · June 1, 2025 Natural rubber has many uses in a variety of industries, enabled by ‘crosslinking’ between its tangled polymers, which creates elasticity. But rubber can crack and suffer fatigue. It is now shown that reducing the crosslink density in highly entangled natu ... Full text Cite

Rapid self-strengthening in double-network hydrogels triggered by bond scission.

Journal Article Nature materials · April 2025 The scission of chemical bonds in materials can lead to catastrophic failure, with weak bonds typically undermining the materials' strength. Here we demonstrate how weak bonds can be leveraged to achieve self-strengthening in polymer network materials. The ... Full text Cite

Fracture of polymer-like networks with hybrid bond strengths

Journal Article Journal of the Mechanics and Physics of Solids · February 1, 2025 The design and functionality of polymeric materials hinge on failure resistance. While molecular-level details drive crack evolution in polymer networks, the connection between individual chain scission and bulk failure remains unclear and difficult to pro ... Full text Cite
