Welcome to the Textiles Nanotechnology Laboratory

Our research group aims at understanding complex phenomena at the nanoscale that are of fundamental relevance to Fiber, Textiles and Polymer Science.

 

The main focus of the Hinestroza Research Group is to explore the interface between the technologically established and mature field of textile science and the emerging and revolutionary field of nanoscale science.  The textile industry was the first beneficiary of the scientific developments from the 18th century's industrial revolution while the nanoscale science and nanotechnology emerged at the end of the 21st century.

Our research group aims at merging two hundred years of innovation history.  We believe that this unusual combination, between an established and an emerging scientific field, can provide unique scientific platforms that will leverage the time-tested manufacturing capabilities of  textile and fiber processing with the ability of nanoscale science to probe phenomena and control the synthesis of materials at small scales.  In order to explore and understand nanoscale phenomena of relevance to fiber science we  pursue a three-pronged approach as follows:  

 

1. Modification and enhancement of existing textile materials using electrostatic self-assembly and atomic layer deposition techniques to create novel, multifunctional and customizable surfaces on conventional textile substrates.

2. Nanomanufacturing of polymeric nanofibers using directed assembly techniques as well as external fields to create novel fibers with unique catalytic, magnetic and electrical properties.

3. Development of metrology tools based on scanning probe microscopy customized to assess nanoscale phenomena on low energy surfaces with high radius of curvature such as those of textile fibers.
