    Abstract: A process for the formation of a deformable battery electrode includes mixing a metal component including at least one of a metal or a metal alloy, a polymer component, and a dispersant component to create a mixture. The method further includes heated the mixture to a temperature above the melting point of the metal or the metal alloy and agitating the mixture to form a dispersion of the (molten) metal or the metal alloy in the mixture. The method further includes cooling the mixture to a temperature below the melting point of the metal or the metal alloy to form a stabilized dispersion of the metal or the metal alloy. The polymer component includes a polymer having a melting point equal to or below that of the metal or the metal alloy and a glass transition temperature sufficiently low that the stabilized dispersion is deformable.

    Abstract: A method of forming a composition includes adding together a plurality of particle brush systems wherein each of the particle brush systems includes a particle and a polymer brush including a plurality of polymer chains attached to the particle. The plurality of polymer chains of the polymer brush exhibit two chain conformations as the degree of polymerization of the polymer chains increases so that the polymer brush includes a concentrated polymer brush region with stretched polymer chains and a semi-dilute polymer brush region with relaxed chains that is radially outside of the concentrated polymer brush region. The degree of polymerization of the polymer brush is no less than 10% less than a critical degree of polymerization and no more than 20% greater than the critical degree of polymerization. The critical degree of polymerization is defined as the degree of polymerization required to achieve a transition from the concentrated polymer brush region to the semi-dilute polymer brush region.

    Abstract translation: 形成组合物的方法包括将多个颗粒刷系统加入到其中，其中每个颗粒刷系统包括颗粒和包含附着到颗粒上的多个聚合物链的聚合物刷。 当聚合物链的聚合度增加时，聚合物刷的多个聚合物链表现出两个链构象，使得聚合物刷包括具有拉伸聚合物链的浓缩聚合物刷区域和具有松弛链的半稀释聚合物刷区域 位于浓缩聚合物刷区域的径向外侧。 聚合物刷的聚合度不低于临界聚合度的10％且不低于临界聚合度的20％以上。 临界聚合度定义为实现从浓缩聚合物刷区域到半稀释聚合物刷涂区域的转变所需的聚合度。
