Poblete Ramírez, Víctor; Álvarez, M. P.; Fuenzalida Escobar, Víctor (Wiley InterScience, 2009)The copper-PMMA conductive composites were manufactured using different copper concentrations dispersed into the polymeric matrix by hot compression molding in inert atmosphere. The PMMA matrix was analyzed using dilute ...

Alvarez, M. P.; Poblete Ramírez, Víctor; Pilleux Cepeda, Mauricio; Fuenzalida, V. M. (JOHN WILEY & SONS INC, 2006-03-15)Copper-embedded low-density polyethylene (LDPE) composites were fabricated using different copper concentrations in the polymer matrix. The copper particles were spherical with a mean particle size between 200 and 300 run. ...
