Abstract:
This research discussed a new way to prepare a construction of polyacrylamid (Am) / polyvinyl alcohol(PVA) semi-interpenetrating polymer network (semi-IPN), using Am, PVA with ammonium persulfate (APS) and N, N’ - methylene bis acrylamide (N, N’-MBA) as initiator and crosslinker, respectively, to improve the dimensional stability of bamboo. The PAM/PVA semi-IPN was characterized by FTIR, SEM and TEM. Bamboo samples were impregnated in vacuum with prepared solution, and then tested with the dimensional stability. The results showed that the physical cross-linking occurred between polymers of PAm and PVA. The pores and parenchyma of bamboo cells were filled up with polymers by SEM. The results of anti-swelling efficiency (ASE) of treated bamboo were 47.1%, 52.9% and 34.2%, respectively. The property of dimensional stability of treated bamboo was improved to some degree.
