Recent developments in stimuli-responsive or “smart” materials offer the opportunity for major advances in material design that could impact markets for latexes. One of the lesser known, but simpler technologies includes polymers and latexes whose properties can be dramatically, and reversibly, switched simply by adding or removing CO2. The processes used offer advantages in sustainability without requiring expensive materials or catalysts, and are based on currently used materials and production methods. This article will give a general overview of three examples relevant to latexes and coatings

Carbon black is commonly used as a filler in rubber and plastic compounds. It is composed of over 90% carbon, with low oxygen and hydrogen content, mainly forming surface functional groups which may participate in polymer reinforcement. Raw almond shells are composed of cellulose, hemicellulose and lignin, representing less than 50% carbon, over 40% oxygen, and at times significant amounts of moisture. The relatively polar nature of almond shells, and their tendency to degrade at processing temperatures, presents a less than ideal alternative when considering fillers for hydrocarbon polymers.
