Resumo

As técnicas de microscopia de varredura por força tem promovido um grande impacto em ciência dos materiais devido a possibilidade de obtenção de imagens em escala que pode chegar no nível atômico. Neste trabalho serão apresentados o princípio básico de funcionamento da microscopia de varredura por força, os vários modos de operação e as forças envolvidas e medidas. O potencial de aplicação destas técnicas no estudo de materiais, e em particular de polímeros, serão discutidos. Uma comparação da microscopia de força atômica com outras técnicas de microscopia será apresentada, assim como exemplos da utilização da técnica de microscopia de força atômica para o estudo de polímeros.

Palavras-chave

Microscopia de varredura por força, morfologia, estrutura, polímeros
