Rubber reinforcing fillers used in the tire industry primarily consist of spherical carbon black or silica nano- or**micro-particles. A game-changing advance would result from the introduction of anisotropic one-dimensional**(1-D) nanostructure-based (e.g., nanorods, nanofibers) fillers that are expected to show unique size- and**directionality-dependent material characteristics.**This project builds on successes of a previous Engage Grant supported effort and will target increasing the**scale of the methods for preparing anisotropic silica and developing an understanding of the factors that**influence nanorod/fiber formation/growth. The resulting materials will be provided to our industrial partner for**testing in rubber composites.

轮胎工业中使用的橡胶补强填充剂主要由球形炭黑或二氧化硅纳米或**微米颗粒组成。引入基于各向异性一维(1-D)纳米结构(例如纳米棒、纳米纤维)的填充物将带来改变游戏规则的进步，这些填充物有望表现出独特的尺寸和**方向性相关的材料特性。**该项目建立在之前Engage Grant支持的工作的成功基础上，目标是增加制备各向异性二氧化硅的方法的**规模，并加深对**影响纳米棒/纤维形成/生长的因素的了解。所得材料将提供给我们的工业合作伙伴，用于橡胶复合材料的**测试。
