Negative thermal expansion in the Sc 2 W 3 O 12 family has been pushed to much more pronounced values by substituting a large cation for Sc. X-ray diffraction measurements from 127 to 627ยฐยฐC give a linear thermal expansion coefficient of ุ 6.8ุ10 ุ6 /ยฐยฐC for Lu 2 W 3 O 12 compared to ุ2.2ุ10 ุ6 /ยฐยฐC
## Abstract Large positive thermal expansion in polymers is one of the major drawbacks in using polymers in applications where the sample dimensions play an important role. In this paper, we report a method to vary the thermal expansion of PMMAโbased polymer composites by blending with a negative t
