Abstract
A process for coating a product by ion exchange including: a) providing a product that contains a surface segregating species (SSS) having a low surface energy component and an ionic component wherein the SSS has segregated to an outer surface of the product to form an activated surface; and b) treating the activated surface of the product with a liquid containing a surface modifying agent comprising one or more polyionic species, wherein the polyionic species is attracted to and deposits on the activated surface through a process of ion exchange.

A process for coating a product comprising:
- (a) providing a product comprising a mixture of a polymer and a surface segregating species (SSS), wherein the SSS is an electroactive additive having a low surface energy component and an ionic component, and wherein the SSS has segregated to an outer surface of the polymer to form an activated surface;
- and
- (b) treating the activated surface of the polymer with a liquid comprising a surface modifying agent comprising one or more polyionic species, wherein the polyionic species is attracted to and deposits on the activated surface, and wherein the liquid has an acidic pH.
