A powder coating composition grindable at non-cryogenic temperatures includes: (a) a first polymer having a number average molecular weight (Mn) of more than 1,000 and a Tg of at least 40&#xb0; C.; (b) a second polymer having a Tm of at least 100&#xb0; C.; and optionally (c) a cross-linker. The first polymer and the second polymer are different from one another, and each of the first and second polymers have less than 25 wt % fluorine-containing monomeric units, with wt % based on the total weight of the monomeric units in each polymer. Upon grinding at a temperature above 4&#xb0; C. the coating composition has an average particle size from 15 to 150 microns. Further coating compositions, methods of preparing coating compositions, coating systems, and substrates coated with a powder coating composition are also disclosed.

A method of producing a radiation diffractive sensor that diffracts radiation according to Bragg's law is disclosed. The sensor is produced by forming an ordered periodic array of particles on a substrate, coating the array of particles with a polymeric matrix, curing the matrix to fix the array of particles within the matrix and contacting the fixed array with an activator, wherein the activator shifts the wavelength of radiation diffracted by the sensor from a first wavelength to a second wavelength.
