Method
ToF-SIMS measurements were conducted using a ToF-SIMS IV (IONTOF GmbH) instrument operated using a 25 keV Bi3+ primary ion source exhibiting a pulsed target current of >0.3 pA. 
Samples were scanned at a pixel density of 512 pixels per mm, with 8 shots per pixel over a given area. 
An ion dose of 2.45 × 1011 ions per cm2 was applied to each sample area ensuring static conditions were maintained throughout. 
Both positive and negative secondary ion spectra were collected (mass resolution of >7000 at m/z = 29), over an acquisition period of 30 scans (the data from which were added together). 
Owing to the non-conductive nature of the samples, charge compensation was applied in the form of a low energy (20 eV) electron floodgun. 
Patch areas of 0.5 × 0.5 mm were acquired at a resolution of 256 × 256 pixels by rastering the primary ion beam over the patch using a ‘random raster’ path sequence. 
Patch areas were sequentially acquired over the entire microarray using programmed stage movements through the macro-raster stage function. 
The patch areas were combined into a mosaic image, allowing all patches to be processed together. 
10 replicate spots were formed for each polymer and included within the array.
Regions associated with the 10 replicates of each polymer were extracted and recalibrated to produce an individual spectrum for each polymer. 

Exported spectra are from 10 replicate polymers. 
Spectra were exported as txt files with a m/z interval of 4 x10^(-5).
Export m/z from 0.5 - 800.0 mass units. Dead time corrected.
Both positive and negative and positive spectra have been provided.
